An electric plane is one of the main tools for woodworking. Properly configured, it is an indispensable assistant in the hands of a carpenter. If, over time, the tool settings have gone wrong, or you don’t know how to prepare the electric planer for work, then it is advisable to get specialized advice, which we are ready to offer in this material. Otherwise, all the work when working with an unregulated plane will go down the drain, and there will be little pleasure from such miserable work.
Like any tool, the plane must be properly adjusted before work. And an electric plane imposes even more stringent adjustment requirements than hand tools. Therefore, the following steps should be carried out before each work with such equipment.
The only warning before inspecting the tool is to follow the safety tips. So the cutting parts of the plane must be treated very carefully. After all, due to the fact that the cutters of this tool are extremely sharp, you can cut yourself on them even when the equipment is turned off, not to mention when the equipment is running. Otherwise, such equipment should be treated like any other power tool.
Procedure for preparing the plane for work
Electric planer engine
The first step is to check the operation of the electric planer motor. To do this, just turn it on at idle. In this case, the drive should smoothly pick up speed, and when it reaches the nominal value, it should operate smoothly and without extraneous noise or rubbing. After which, it is advisable to check the operation of the power unit under load - when it rests on the workpiece, it should pick up speed and hold it. In this case, no extraneous sounds should be observed.
Next, you should check the ventilation holes where the brushes are located. When the electric planer is running, there should be no sparks there. If there are sparks, then most likely the ventilation holes became clogged with small chips during operation. You should blow them with an air stream from a compressor or clean them with a brush. Considering the design and operating conditions of an electric planer, this procedure should be done constantly.
If the described actions did not lead to the desired result, then you need to check the brushes themselves. They may have worn off and need to be replaced. If this does not help, and the plane “sparks” when used, or, even worse, there is a burning smell from it, then you should stop working immediately. It needs to be taken to service. If everything is done on time, it will soon serve you flawlessly again.
Advice: when you want to choose an electric planer, first of all look at the power and number of engine revolutions. For long-term operation, the power must be at least 750 W, and the number of revolutions must be at least 12,000 per minute.
Electric planer knives
It is clear that the sharper the cutting edges of the knives, the easier it is for the tool to do its job. Knives should be inspected regularly and sharpened as needed. A sign that the knives are dull is that the plane is working harder than usual. It has to be constantly pushed when planing. At the same time, the engine wears out, making a characteristic sound of overload. This should not be the case, because the smooth running of the tool is created due to the high power of the engine and high shaft speeds, and not due to the muscular strength of the operator.
Sharpening planer knives, like regular knives, is done on any sharpening machine. The skill of sharpening is to ensure that the cutting edge is equally smooth along its entire length. Remember, if your model has several knives, and there can be from 1 to 3, then you should sharpen everything. When the instrument operates, they act as one whole. Differences in sharpening upset the balance of the knives and will immediately “come out” in the form of a poor-quality cut.
Tip: Try to buy an electric plane with thick blades. The knives on this model of electric planer are metal plates 20 mm in length (not to be confused with the width, which is usually 82 or 110 mm according to the standard). On inexpensive planes, the knives are no more than 5 mm, the difference is obvious, and such cutters, like the entire unit as a whole, will last much less.
Electric planer belt
Few people know that the design of an electric planer includes a special belt. It transmits movement from the motor armature to the shaft with knives. But, since it is hidden inside the tool (under its side cover), it is not visible and, accordingly, many underestimate its participation in the operation of the equipment. But in vain, because this unit is a closed belt with cut teeth. With the help of these teeth, motion is transmitted to the shaft. Over time, the belt becomes unusable and stretches. If you have performed all the above steps, the plane engine is running, but the blades are not under load, then most likely the problem is in the belt.
Tip: Buy a plane with a rubber belt. When you want to buy a plane, ask the seller what kind of belt it has: rubber or silicone. Rubber is of better quality and lasts longer.
Yes, the tips are simple, but the main thing is to have the will and patience to follow them. The quality of care for your instrument always affects the quality of the finished product. Remember this. Carry out preventive maintenance on time, and repair of the electric planer will not be necessary very soon.

Small stationary electric hook
A person in whose house many things are carried by his hands has in his arsenal a set of special tools, among which, if he works with wood, also small electric planes that are suitable for planning.
Such a tool can be found in the price-stroy.ru catalog of the online store of building materials “Price-Story” - your reliable assistant in construction and repair. The electric plane is mobile, you can take it at any time, for example, to the dacha or in the garage, that is, wherever it is needed.
Unfortunately, this tool is not universal, for example, if you need to pull a small and narrow stick, you need to fully adjust the workpiece repair; this cannot be done manually because the tool is in the hands. In addition, it is inconvenient to use when working with a small part that is completely covered by the plane.
Electric planner, 100mm cutter width, equipped with a tool, does not rotate the tool in the sleeping device, the above disadvantage can be avoided, the same 75mm roll blades, but this tool can be improvised by a small device plays the role of a console.
This will require a 20mm piece of plywood measuring 450 x 300mm on a pair of posts, each in two pieces, which are in four pieces, which can be made from 10mm plywood in a variety of configurations.

Select a brand of electric planer
A hand-held electric planer is a tool that is used for planing wood in the process of manufacturing wooden structures. You can disassemble the device yourself according to the instructions.
Components
The electric planer is powered by connection to a network with alternating current, frequency 50 Hz and voltage 220 V. The safety of craftsmen working with the tool is ensured by a double layer of insulation. Therefore, a protective shutdown mechanism and grounding are not required.
Construction details:
- commutator single-phase motor;
- cutters with flat knives;
- flat belt drive;
- frame;
- mechanism controlling planing depth;
- front movable support;
- lever;
- conductive cable with plug.
The electric motor housing must be attached to the equipment housing. Double insulation is ensured by insulating the armature shaft of the electric motor and using plastic to make the housing. The engine is cooled by a fan, which sucks air through slots on the housing cover. Air passes through the engine and is exhausted through holes in the intermediate shield.
A cutter with 2 flat knives is a cutting element of the structure. The knives are secured with bolts and a wedge. The cutter, using a belt drive from an electric motor, rotates in 2 bearings, which are pressed into the cover and body of the structure. The belt drive parts are driven and driven pulleys, which are connected by an endless belt 15 mm wide and 2 mm thick.
You can adjust the planing depth from 0 to 2 mm by turning the additional handle. The movable support will move along the guides of the unit body. The handles and electric motor are mounted on a common plate. It is moved by adjusting screws, ensuring the tension of the drive belt drive. The belt deflection should not exceed 2-4 mm. The main handle has a built-in radio interference suppressor and a latching switch.
How the device works
The main element of an electric planer is a rotating drum on which flat knives are attached. It is necessary to select an electric motor for the equipment with a power of at least 580-900 W at a speed of 1000 rpm. since the texture of the wood being processed may be uneven, and the surface of the planed parts must be smooth.
The rotational movement from the motor is transmitted to the cutter using a toothed drive belt. The base of the equipment is made of cast aluminum. It is divided into 2 parts, in front and behind the cutter. The front part is adjustable in height, allows you to set the required chip thickness and moves along the untreated surface of the wood. The back part is stationary and moves along the planed surface.
The rotating drum of a large number of models is open on one side. The side limiter installed in most models allows you to select the width of the quarter. The unit can additionally be equipped with a protective folding cover on the side surface, which can be removed by selecting a quarter.
Experts advise disassembling an electric plane using a set of keys and a screwdriver.
To disassemble the electric planer, remove:
In units with V-belt transmission, we will analyze the pulleys, casing and belts. In the process of disassembling the housing, it is necessary to remove the nuts, unscrew the bolts, and separate the halves of the plastic motor housing. The next stage of disassembly involves disconnecting the wires, removing the capacitor and switch. Then the cover from the electric motor, brush holders, brushes and rear shield are dismantled.
The armature is removed, from which the ball bearings and fan are removed. The cutter is removed and the covers are removed. The cutter is disassembled and the knives are removed. The next stage involves dismantling the front support and disassembling the mechanism that regulates the planing depth.
Carrying out woodworking work is unthinkable without the use of special tools. Most models of electric planers are aimed at a specific type of work. For this reason, it is recommended to choose a tool purposefully. How to do this?
Professional electric planer Makita
It is known that manual woodworking is the most labor-intensive process. Hewing, planing and quartering are considered basic carpentry work. Naturally, doing this work using a mechanical plane takes a long time.
Manufacturers of power tools designed for woodworking have created highly efficient planes. Among the variety of electric planer models, Makita occupies a leading position. The demand for an electric planer determines the range of work performed in the domestic and professional sphere.
Let us remind you that according to the parameters “power - functions - price”, household and professional electric planers are distinguished.
Household ones have a power of up to 1 kW, a planing width of 80-110 mm, a penetration depth of 2.5 mm and an affordable price.
A professional Makita plane, the price of which is impressive, more powerful from 1.5 kW, a planing width of 110 mm and a penetration depth of up to 4 mm. Accordingly, the pros are well equipped with additional features, which excludes inexpensive models.
To make the right choice when purchasing, it is useful to know the basic functionality of the tool and technical characteristics.
Choosing an electric planer
Electric planers of the Makita model range from the manufacturer are distinguished by power, blade width and cutting thickness, as well as by operational parameters - overall dimensions and weight.
Therefore, when planning to buy makita, pay primary attention to the following parameters:
- input and output power consumption
- speed and rotation frequency of cutting parts
- presence of a dust collection system
- width and depth of planing with the possibility of adjustment
- power supply
- availability of electronics (soft start, brake and overload protection).
To thoroughly understand the capabilities of the tool and make the required choice, study the design of the makita model electric planer.
Useful tips
How to distinguish a real Makita brand. A branded instrument is distinguished by a nameplate or plate located on the top of the body.
It’s easy to find the difference between Makita-san and the “Chinese”: Makita Corporation, 3-11-8, Sumiyoshi-cho, Anjo, Aichi 446-8502, Japan and Makita China Co. Ltd. , 288 Huangpujiang Road, Kunshan Economic & Technological Development zone Jiangsu 215300.
Judging by the reviews, Japanese brand Makita planes are also distinguished from fakes by the weight of the tool. For example, the weight according to EPTA 01/2003 of the KR0800 plane will be 2.6 kg, the KR0810 model weighs 3.2 kg, and the VKR180 model weighs 3.4 kg. Fakes will weigh much lighter due to the replacement of cast parts.
Design of the Makita electric planer
Structurally, electric planer models consist of the following elements:
- robust housing with ergonomic handle and built-in electric motor
- nozzles for connecting a vacuum cleaner and dust collector
- planing depth adjustment handles
- soles with electric knives
- electrical cord.
Let's take a closer look at the design and capabilities of the tool using the Makita 1806v electric planer as an example.
The electric planer is a professional tool for planing medium and hard wood in lengthwise and crosswise directions. The 1200 W motor power and a wide 170 mm carbide blade allow you to process plastic and laminated wood.
Please note that the design features of the fastening make it possible to use the tool as a jointer, and be in demand for significant volumes of woodworking.
The mobility and smooth movement of the tool is ensured by a cast aluminum platform, and the depth of penetration in one pass is ensured by the regulator on the front part, which is also a stop handle. The planer shaft and the plane drum allow you to use two types of knives for the Makita plane.
In addition, a parallel stop and a chip suction system with a wide socket ensure uniform sampling of the quarter.
The standard connection scheme, 8-85K cable amplifier and double insulation provides the ability to connect to ungrounded outlets.
The ergonomics of the Makita 1806v model with a low center of gravity of the cast plate is ensured by a comfortable handle. The durability of the working tool is thought out due to the cooling system and a powerful power cord. By the way, the electronics of electric planes of the entire model range are reliable, if available.
Useful tips
When choosing a tool, pay attention to the scope of delivery. The manufacturer's delivery set includes: adjustment devices for the thickness of the layer being removed, a system for changing cutting blades and protection for knives and a power cord from 2.5 to 10 m long.
In addition, you need to find out the addresses of equipment service centers where they produce high-quality replacement of the “native” parts of electric planers: stator and rotor assembly for 1806B/1805B, HSS knives 170x35x3mm, bearing 6200ZZ, boot and impeller.
What an electric planer can do
When choosing a tool, you need to focus on the volume and specifics of woodworking work. What operations will an electric planer be capable of in capable hands?
tool for removing chamfers and panels
For example, the ideal tool for planing smooth surfaces, chamfering and creating panels is the makita 1902 model.
Uniform sampling to a given width and depth of a recess of up to 9 mm will be ensured by installing a parallel stop on both sides.
For chamfering, the front of the plane sole has a V-groove and single- and double-sided carbide blades with a high-speed steel (HSS) blade. By the way, the service life of universal knives allows them to be reused by sharpening and grinding the blades.
If you intend to use a tool for finishing the surface of wood, then it is better to give preference

The Makita 1911v electric planer is equipped with a wide cast plate (110 mm) made of aluminum, which makes it easy to guide the tool along the surface.
Sliding along the working surface is ensured by the front roller.
The insertion depth is 2 mm, ensuring easy movement along the surface of the material.
The built-in dust extraction system with a wide tube eliminates the appearance of wood dust.
For this purpose, a lateral woodworking waste removal system was used.
The possibility of adjusting the planer and attaching the plane to the stand ensures ease of use and eliminates injuries. The tool is equipped with a rotating cutting knife, a parallel stop and a holder for sharpening the working parts of the plane.
Introduction
Electric is one of the main tools designed for carpentry. Not a single craftsman who professionally works with wood can do without this device. And the average user, especially those living in rural areas, or simply in a private home, often comes across materials that require the use of this tool.
Types of electric planers
As with many other power tools, electric planers are conventionally divided into amateur and professional. The latter are distinguished by greater weight, power and maximum sampling depth.
In addition to the division given above, many distinguish planes with the possibility of stationary installation, electric and conventional hand planes.
Planer with stationary installation.
with such a useful addition as a stationary installation, it allows the owner to use the tool both for its usual purpose, that is, to process the surface of a wooden workpiece, making longitudinal movements along the workpiece, and to turn it into a small woodworking machine, turning the device over and securing it to a fixed support .
It can be mounted on a simple table or carpentry bench. The main thing is to do this reliably in order to eliminate the possibility of the operator receiving various injuries during the work process.
Planer with stationary installation rebir ie 5708m |
INTERSKOL domestic plane with stationary installation |
As a rule, working with a tool converted into a planer requires the presence of an assistant, since large wooden products are usually processed on a stationary device.
This process occurs as follows - one of the operators, holding a wooden workpiece in his hands, one end of which rests on the sole of the electric planer, gradually moves it forward with the force and speed that implies high-quality processing of the product.
As the workpiece advances, the second operator, standing on the opposite side, accepts the workpiece so as not to disrupt the speed of movement of the wooden board along the sole of the tool.
Typically, planers with the possibility of stationary installation have richer equipment, increased power and increased planing width compared to their counterparts that do not have such an additional function.
The power consumption of such stationary devices is 1500-2000 W, while the power of simple electric planes rarely exceeds 1000 W. The width of the knife, and therefore the planing width, as a rule, for stationary planes is 110 mm. For comparison, for other electric planes this value is 82 mm.
The planer with a stationary base includes:
- Bed (also known as a stationary installation, some also call it a stand);
- Bolts for fastening the tool to the frame;
- A parallel stop, which serves as a limiter for the width of the workpiece. Marks of geometric dimensions are marked on the stop so that the operator has the opportunity to select the required value before work, without having to make markings using a ruler and pencil;
- A fabric bag for collecting waste (shavings);
- Set of carbon brushes. In some models, the manufacturer provides an easy access device for changing brushes. This allows the owner to independently replace this consumable without contacting a service center;
- Key for mounting planing knives;
- Quarter stop.
Electric planer STURM with complete set
As can be seen from the description, a plane of this type is a universal device, implying both manual use and operation as a woodworking machine.
Electric planers are an essential tool for modern carpenters, joiners, and all specialists involved in processing lumber. Their prevalence is due to practical efficiency and the presence of significant advantages of this equipment compared to manual analogues. To fully utilize the device's potential, electric planer blades must be pre-adjusted before processing wood. Also, the blades must be sharp. This, together with the correct adjustment of their position, will allow processing significant volumes of boards or beams without any problems or effort on the part of the user.
Knives on an electric planer are consumables. With their help, wood surfaces are processed.
Often knives come complete with power tools in the amount of 2 pieces.
Electric planer knives are classified according to the following criteria:
- opportunities for practical reuse;
- blade shape;
- knife blade sizes;
- cost.
When buying an electric planer, in addition to checking its performance and configuration, you should pay attention to the quality of the knives installed on the drum and their sharpening. The blades should be sharp, with a straight edge and no bends or gouges. You should also check spare knives. The final quality of lumber processing depends on the correct selection of cutting attachments.
Knives intended for one-time use are made from steel-based hard alloys in the form of plates sharp on both sides. Such cutting parts cannot be sharpened. After the edge being used is completely worn out, the blade is turned over and placed on the drum with the other side. At the same time, the tool continues to work. If the second cutting edge becomes dull, then the blade is simply thrown away.
Disposable knives are intended only for performing work that does not require high precision and quality of workpiece processing. But they are convenient for practical use: during installation they do not need to be precisely adjusted and balanced.
The shapes of disposable products are:
- straight;
- wavy;
- straight, but rounded at the ends.
The first type of product has a straight cutting part. It is convenient to use such consumables to process parts that have a smaller width than the length of the installed blade, and to select quarters. Wavy knives are used when necessary rough processing of lumber. With their help, you can give a wooden surface a different texture, for example, to simulate “aging.” Straight cutting edges, rounded at the edges, are good because they do not leave marks (grooves, steps) on the surface of the wood being processed. This is a suitable option when work needs to be done with wide wooden blanks.
Disposable blades have a longer service life, but can break quite easily if they accidentally collide with metal (for example, a nail, bolt). They are the best option for attachments when it is necessary to work with hard wood workpieces.
Reusable cutting attachments
Products that are intended for reusable use differ in both their shape and size from disposable cutting attachments. They are made using high quality steel, which ensures ease and quality of processing of wooden surfaces.
Using reusable knives, you can achieve such a smooth surface of the workpiece that grinding is not required. They have HSS marking(completely High-Speed Steel, which translates as high-speed steel). These blades are considered professional. Their installation is accompanied by high-precision balancing and adjustment. The sharpening must also be of excellent quality. In this case, tool high-speed steel can be sharpened so that it is very sharp.
It is more profitable to buy reusable cutting attachments because they can be sharpened multiple times. But high-speed steel products do not allow processing hardwood (for example, larch or oak).
The working drums of most models of electric planes can be equipped with both disposable and reusable cutting attachments. But there are also devices that can only be equipped with blades that are not intended for sharpening. For this reason, when purchasing an electric planer, it is recommended to give preference universal power tools.
Classification by size
Electric planer knives can be standard or custom size. Products of the first type, called “plates,” have a length of 82 mm, a width of 5.5 mm, and a thickness of 1.2 mm. Such cutting attachments are suitable for most models of electric planes from foreign companies Makita, Skil, Bosch, Black&Dekker.
Straight knives for electric planers Bosch, SKIL
Non-standard cutting attachments with larger blade widths and thicknesses are typical for electric planers from Baikal and Interskol. Due to their parameters, they are stronger and better than standard plates. When they come into contact with metal, such knives do not break. They can be sharpened using sandpaper. The width of the nozzles is about 1 cm. The length can be 82 mm, 102 mm, and for products from the Rebir company it reaches 110 mm.
Straight knives for electric planer Rebir IE-5709
Cutting head price depends on the manufacturer. Also, this factor often determines the quality of the product. If you purchase knives from well-known companies (for example, Bosch), you can count on their long service life.
Some models of electric planers are equipped with cutting attachments of unusual shape and design. In order not to be mistaken with the dimensions, it is recommended to take the old blade with you for comparison before purchasing.
When do you need to adjust or replace electric planer knives?
The knives on an electric planer wear out over time. They need to be removed and sharpened or replaced altogether, and then put back on the drum. Newly installed cutting attachments need to be adjusted in order to process lumber as efficiently as possible. The blades of new power tools also require pre-setting. before use.
The following signs indicate that adjustment is necessary:
- change in sound when processing workpieces;
- vibration of the tool during operation;
- deterioration in the quality of planing lumber (formation of waves, chips, grooves, protruding fibers and other defects);
- increase in effort spent on work.
The change in sound is not typical for all models. This symptom may also indicate a number of other problems.
If, after adjusting the blade blades, the symptoms discussed above do not disappear, then more serious repairs to the power tool will be required.
Setting the correct position of the cutting attachments is carried out according to the following parameters:
- the height of the part of the blade that protrudes above the sole of the power tool;
- the size of the side protrusion of the knife intended for picking out quarters.
By correctly adjusting the position of the knife blades on the drum, high final quality of lumber processing is achieved.
How to properly adjust knives
Adjusting the knives on the drum yourself is not a big problem. To set the position of the tool blades before work, you will need:
- hex wrench included with the plane;
- metal ruler or piece of glass of suitable size.
The setup is carried out by performing all operations in this sequence.
In the considered sequence, the working position of the cutting edges is adjusted for models of electric planers with one, two or three knives.
It should be taken into account that the working parts of straight-shaped knives should protrude by approximately 0.5 mm, and rounded ones by 1 mm or more.
If the adjustment is carried out correctly, the cutting edges on the drum should be parallel to the sole of the power tool without distortion. A number of new models contain adjusting screws, which simply need to be twisted to install the knife plates in the desired position. To set up the tool, it must be disconnected from the power supply, and in cordless models, the battery must be removed. This will ensure that the power tool does not start spontaneously.
Algorithm for replacing knives on an electric planer
To remove the knives from the electric planer and replace them with new ones (or properly sharpened ones), you will need a set of wrenches, and also, in some cases, a screwdriver. There is no need to completely assemble and disassemble the electric plane to change working attachments. Replacement is performed in the following sequence:
- rotate the drum, placing it in such a position to gain access to the knife mounting bolts;
- loosen, but not completely, these bolt clamps;
- remove the working attachment manually or using a flat screwdriver;
- the rest of the blades are treated in a similar way;
- place new knives in the sockets, securing them with bolts;
- put them in the correct position.
The main point is the need to place the blades exactly in the sockets and securely fix them so that they do not fall out while using the tool. Due to the fact that different models of electric planers may have different attachments for working attachments, it is recommended that you first read the operating instructions for the equipment you are using.
On sale you can find knives whose blades rotate. This is very convenient because it is enough to simply turn over the dull edge, replacing it with a sharp one.
When the drum of an electric planer is installed two cutting attachments, you need to change both at once. This will prevent the occurrence of an imbalance, which results in a decrease in the quality of lumber processing and failure of the electric planer.
Sharpening electric planer knives at home
With regular use of an electric planer for processing wooden surfaces (planing, quartering, chamfering), its cutting edges become dull. If the knives are intended for reusable use, then you can sharpen them yourself. Sharpening is carried out according to the same principle as with hand planes. The differences are only in the number of cutting edges that need to be sharpened.
Use power tool with dull blades This is not possible for the following reasons:
- the load on the electric motor increases, as a result of which its wear accelerates;
- The quality of surface treatment of lumber is significantly reduced.
Specialists from service centers or special workshops will help you sharpen the cutting edges of working attachments correctly. If it is not possible to turn to professionals, then you can do all the work at home. To sharpen your blades yourself, you can use the following tools:
- knife sharpening machine;
- an ordinary whetstone (abrasive stone, whetstone);
- emery;
- metal file;
- grinding wheel.
You will also need special clamp to hold the part being sharpened.
Sharpening a blade using an abrasive stone is done as follows.
- Remove the working attachments that need to be sharpened from the electric planer drum.
- The knives are secured using special screws in the clamp so that their cutting edges lie in the same plane.
- The fixed blades, with light pressure, move smoothly over the surface of the abrasive, ensuring that they are sharpened at the same time.
- Inspect the sharpened parts for deviations, repeating the entire process if they are detected.
