What to evaluate when choosing
- Grinder power. For the category “household tool” 1 kW is sufficient. is unlikely to be needed.
- Speed regulation range. The larger it is, the wider the scope of application of the grinder. Such CMM work with all types of “skins”, therefore, they are suitable for processing various materials. metals (removing rust, preliminary polishing), wood (stripping, cutting off the remaining knots, etc.).
- Linear parameters of the tape (mm). For household models, the standard width is 76, but along the length there is a certain size range (standard). 457, 533 and 610. The last samples are larger, but with their help it is more convenient to process workpieces such as a board, log, timber or flooring with a large area.
- Centering mechanism. In the process of work, the tape is constantly shifting (“leaves” from the rollers), and it has to be periodically corrected. The presence of a special device greatly simplifies this task, since the adjustment is performed automatically, and you will not have to spend time on it.
Starting
What can be done with similar models?
- Removal of foreign deposits (scale, rust, oxides).
- Removing a layer of old paint.
- Cleaning of wooden surfaces (plank and parquet floors, external walls, etc.).
With certain skills, brush grinders are used to artificially age wood products.
How to choose a reliable wood sander. all parameters and types
The processing of most types of wood, due to its not too dense structure, is not particularly difficult. But if it is necessary to achieve high quality, to prepare the material for subsequent coating (for example, with varnish), then you will have to spend a lot of time and effort using only traditional methods (plane, file, sandpaper). Unfortunately, not every home has a wood sander.
And first of all, for the reason that not everyone is familiar with its capabilities. This article will not only help you understand that a good owner really needs a wood sander, but also tell you how to choose it correctly.

Brush models
They are distinguished into a separate group, although this is just a type of tape CMM. The working tool is a shaft-mounted brush that does the roughest work.
Useful Tips
Practice shows that if the rules for choosing a grinding machine are basically clear to everyone, then you cannot say the same about the criteria by which an abrasive cloth is evaluated. It is this question that confuses many.
What to evaluate when choosing
An increase in these characteristics leads to an increase in the cost of the grinding machine. In fact, these are already professional models. And it is up to the buyer to choose them for home or not.

angle grinder. angle grinder
The well-known angle grinder can also be used for sanding wood. It copes well with the coarse grinding function. Of all the tools available, this one is the most productive. If you need to quickly level large wooden surfaces. sanding the floor, walls, logs. this is the job for an angle grinder. Minus. the surface turns out to be very uneven, it takes a long time to align all the pits and humps. If it still “passes” on the log house, then the result is unsatisfactory for any carpentry work. If you can buy another tool, you should not use an angle grinder to sand wood.
For wood, use red emery wheels. this is a special abrasive
For the angle grinder, there are special attachments for sanding wood. The best option is flap discs or discs with different grit sandpaper. When installed, the working plane is below the protective cover, it is safe to work, you can move in any direction. Carefully it is necessary to handle places with protruding heads of nails and screws. We lower the tool from above, carefully move it. The grinding wheel easily breaks with a sharp movement, so be careful.
By varying the grain size of the grinding wheels used, it is possible to carry out coarse and medium (intermediate) grinding. The work will take less time than if you use any other sander for wood. But it may take more time to bring to a flat surface, since, with a lack of experience, there will be more flaws.
When sanding wood, the sandpaper becomes clogged, the speed of work decreases. In addition to a decrease in speed, there is another sign. the smell of burnt wood. It is not necessary to change the disk right away, you can restore its operability. To do this, grind the metal for a few seconds. Everything adhered. resin, wood fibers, dust. burns, the surface is cleaned, the processing speed increases again. This Focus, by the way, can be used with other grinders as well.
If you often have to clean and change the wheels, a Velcro attachment is installed on the angle grinder. Replacing the sandpaper is much easier and faster. unpinning / sticking is a matter of seconds. But working with a nozzle is more dangerous. Due to its height, the grinding area is above the level of the protective casing, it does not perform its functions. During the start, it happens that an unreliably fixed circle or even the nozzle itself flies off. They have a small weight, injuries are not serious, but they are all the same injuries. An angle grinder with a smooth start helps to reduce the risks, but, anyway, you need to work with gloves, protective clothing with tightly buttoned sleeves, boots that cover your legs, and goggles.
Eccentric (orbital)
In addition to all the general parameters described, the choice of an eccentric wood grinding machine has its own nuances:
- The amount of eccentricity. That is, the amplitude of the deviation in a circular motion. It can be from 2 mm to 8 mm. The higher this figure, the higher the processing speed, but the lower its “purity”.
- Outsole diameter. There are 90 mm, 100 mm, 125 mm and 150 mm. Professionals prefer to work with a sole diameter of 150 mm. They have the highest performance and for this size there is a large selection of sandpaper of different grain sizes, there are no problems with spare parts.
Orbital sander for wood: it is important to choose the right eccentricity
Vibrating
The sole of the vibration sander can be rectangular or triangular. During operation, it makes circular movements with a small amplitude. it vibrates, which gave the name to this type of equipment. This wood sander is used for fine finishing. for varnishing or painting, but has a low performance.
A vibrating sander for wood with a rectangular surface allows you to process large areas, but with its help it is not possible to sand wood near vertical planes and walls. it starts to beat against an obstacle. Triangular in this regard is more suitable for working in corners and hard-to-reach places, but you still cannot bring it tightly to the wall.
The vibrating machine is used for finishing
Another disadvantage of vibrating systems is the so-called “lambs”. If a grain of sand or other solid fragment gets under the surface, it leaves small circles on the wood. “lambs”. Removing these marks is difficult. It is necessary to use sandpaper of increasingly fine grain, gradually removing scratches. But if in the process something gets under the sole again, the process is repeated again. Therefore, before work, the surface is thoroughly cleaned and the plyosos is usually connected. for quick and timely removal of extraneous fragments.
What type of sander to choose
To summarize, we can say that for housework and construction, ideally, two grinders are needed. for a rough and a fine finish. The most commonly used pair is tape eccentric. If you are planning to make furniture, then you cannot do without oscillation.
If you do not like the result of a belt sander, you can purchase two orbital ones with different eccentricities. For rough grinding, a tool with an eccentricity of 6-8 mm is suitable, for finishing grinding and even polishing. 2-4 mm. The only drawback of this solution is that good eccentric sanders are expensive.
If the budget is limited, and the farm has an angle grinder (angle grinder), rough grinding can be done with it, and for intermediate or fine grinding, use orbital or vibration. Just keep in mind that vibration is the least productive, albeit the cheapest. If possible, buy an orbital one. it is more versatile and gives better results.
How to choose a sander for wood
On the farm, you often have to grind something, clean off the old paintwork. Most of the work is with wood. Few manufacturers sell perfect pieces. Perhaps a carpenter. And if there are perfectly processed boards, then their price is such that you will inevitably want to polish them yourself. Even taking into account the fact that the work is boring and uninteresting. Therefore, a wood sander is one of the tools that should be in the home arsenal.
Tape
When choosing belt grinding, you need to look at the following parameters:
-
Length and width of the tape. Belt width. from 6 mm to 100 mm. A narrow blade can handle small parts, a wide blade increases productivity. The length of the tape depends on the model. It is clear that the longer the tape, the longer it works without replacement. When buying a second belt sander, try to find a model with the same length. fewer consumables are required.
The width of the tape can be different
Additional handle allows for tighter control of the tool
You also need to pay attention to how convenient it is to change the tape. There are also models that allow you to quickly change the brushes. Sometimes spare brushes are even included.
Technical selection criteria
Any tool is divided into classes that differ in work resource (and price). So a sander for wood can be household or professional. Household ones are designed for short continuous work with interruptions. Basically, it is recommended to work no more than 3 hours a day, periodically taking breaks of 15 minutes.
Professional models are designed to work for 8-12 hours, breaks are rarely needed or not needed at all. The working resource of such a tool is many times greater. For this, durable and reliable (read. expensive) materials are used. In addition, the performance of such equipment is much higher, as a rule, there are more adjustments.
To choose a wood sanding machine, you need to pay attention to the technical parameters
When choosing, the first thing to decide is what class your car should be. I must say that some manufacturers have a good household class, and some also have semi-professional lines. This is an intermediate class, as a rule, for private use it is optimal in terms of price / quality combination. Some models are even used by professionals.
Types of cars
There are several main types of grinders for household use on sale. Each grinder has its own design features and mechanism of action.
For carpentry, joinery, construction and repair work, the following types of power tools are selected:
- wood belt sander (LSHM) is designed for rough and aggressive surface treatment, including plastic, metal;
- Brush grinders allow you to highlight the texture of the wood, removing more soft fibers, remove layers of varnish, old paint. The working part is a roller on which a metal or abrasive nylon brush is put on;
- an orbital sander (VShM) is used for a softer finish. Gentle working thanks to circular motions and small working tool amplitude. The outsole is rectangular for easy cleaning of corners;
- delta sander is a type of flat orbital sander with a triangular sole. Such a device is suitable for processing hard-to-reach places and small areas, as well as depressions, corners, irregularities;
- an eccentric sander is a power tool that allows you to bring the surface to be treated to an ideal state, including plywood. This task is accomplished by the rotational and oscillatory movements of the sanding pad. The device has a high degree of performance, but cannot be used for cleaning inside corners and small surfaces.
The wood grinder is an indispensable tool for processing walls, floors, interior items and other decorative items. It is able to speed up the process of grinding and polishing surfaces made of natural material several times.
Draw frame
In a wood belt sander, the working element is represented by a belt fixed around two rollers. During their movement, the tape, fixed on the sole, is brought into working condition and rotates at the required speed. It is the speed that is considered an important indicator of the operation of this device and it depends on the power, which can be in the range of 500-1200 watts. There are tools equipped with an additional speed regulator, which allows you to select the most optimal option for each type of surface.
The sizes of the belt are different, depending on the modification of the grinder. The most functional device has the highest rate. At the same time, the weight and dimensions of the structure will also be significant. When choosing a power tool, special attention should be paid to the grain of the tape used. For ease of use, it is necessary to have several types of tapes with different grain sizes. One of the varieties of a belt sander for wood is a brush device that performs the most coarse processing.
Possibilities of an angle grinder, discs for it
An angle grinder (angle grinder) can also be used for sanding wood. With its help, you can make rough processing.
This tool allows you to quickly clean up wooden surfaces, in particular, sand the floor and walls. This versatile machine is capable of performing a wide variety of operations, with the appropriate wheels for each: cutting, grinding and roughing (grinding).
an angle grinder can cut metal, stone, wood. But it is undesirable to saw boards and other wood, otherwise the tool will overheat. Saw blades for wood for an angle grinder resemble modern saw models, but other alloys are used for their manufacture. The only drawback of the angle grinder is the presence of various irregularities after work, which then need to be leveled for a long time.
For grinding work, special red wheels are used. A good option is to use flap or disc wheels with the appropriate grit for each application.
Considering that the working plane is located under the protective casing, performing specific actions does not pose a danger to a person, which makes it possible to move the tool in any direction. The main thing is to be careful when working with surfaces on which there are protruding caps of screws, nails.
Note! To make it easier and faster to replace the sanding paper, it is recommended to attach the sticky attachment to the angle grinder.
Oscillating wood sander
This electric tool is a multifunctional renovator that is also capable of sanding wood surfaces. It differs from other instruments in its budgetary price and very low power consumption. It can be used to handle sharp corners and places near vertical walls. To carry out this manipulation, a special triangular platform is installed on the grinder, to which a grinding wheel is attached on a self-adhesive base. In addition, the device makes it possible to effectively clean the floor from glued linoleum, tiles, create slots, cut communication mowing lines.
During operation, the sole moves in a horizontal plane with a minimum amplitude, the platform tops deviate by an average of 2.5 mm (1.7 degrees). Due to these movements, surfaces are processed. Such a device can be used for grinding corners and other hard-to-reach areas. The machine does an excellent job not only with removing wood, but also with smeared or dried glue. In general, the oscillating apparatus is used for finishing in places where other machines cannot cope due to their low performance or a sanding spot.
Vibrating sander
The sole of the vibration-type technique can be triangular (ironing) or rectangular. During processing, it performs circular movements with a small amplitude. The machine is used for those cases when it is necessary to obtain a high-quality surface, for example, to restore furniture before applying stain, varnish. Sanding is required especially carefully, since all flaws will be clearly visible through the transparent layer of the topcoat. At the same time, the device has low performance.
Note! Choosing a rectangular sole is better for finishing large areas, and for corners and hard-to-reach places it is advisable to use a triangular shape.
When working with a vibration sander, it is imperative to remove debris, any solids, grains of sand, so that small circles. traces. do not form on the surface. To remove such defects, you will need an abrasive wheel with the smallest grain size. The treated wood surface must be well cleaned with a vacuum cleaner.
Five types of wood sanders
Wood, as one of the most popular and convenient finishing materials, does not cause any particular difficulties in processing.
But in order to achieve a perfectly smooth surface, for example, under varnishing, ordinary carpentry tools will not work. The wood sander can speed up and facilitate the alignment.
This multifunctional device is presented on the market in various modifications, differing in design and application features.
Criterias of choice
When purchasing a specific model of grinding equipment, you should take into account the tasks that the power tool must perform in the future. The choice of professional or household equipment depends on this.
Professional wood sanders are ideal for long, active and continuous work. They will cost much more than household tools. For use without significant loads and long-term work, it is worth giving preference to simpler grinders. If the choice is between a professional device and an ordinary one, then it is better to purchase the first option, despite its high cost. If the second one was chosen, then when working with it, it is recommended to subject the device to higher loads less. Pause every 3 hours. Only adherence to simple operating rules will extend the service life of the tool.
It is also important to consider the type of work for which the sander is selected. For smooth surfaces, the best solution would be to buy a belt sander. If there is a need for grinding or polishing decorative wood products, then it is recommended to purchase eccentric models. The ratio of the cost of consumables and the forthcoming costs during the operation of the device must also be taken into account.
If you intend to use a grinder indoors, then you should pay attention to equipment with a built-in dust collector or the ability to connect a vacuum cleaner. Considering that a lot of dust will form during the sanding process, you need to prepare for its appearance everywhere. Manual cleaning of the premises takes a lot of time and effort.
The length of the cord plays a significant role when choosing a model of a grinder. Since it is inconvenient to work with the device on a short cord, and an extension cord is not always possible to use.
Battery-powered tools are on sale, which are relevant when working in the country and in houses where electricity has not yet been supplied. The cost of such models is high.
When choosing a device, you should test the location of the handles, check whether it is convenient to switch modes, how hard it is to hold the typewriter in your hands.
