Construction or renovation work is not complete without purchasing a wood sander. But which one should you choose? Most often, a tool is selected based on its ability to work with a specific material, the size of the area being processed, and the presence of hard-to-reach areas.
For professional construction or renovation work, you will need a high-power wood sander.
Wood sanding machines are:

• tape;
• vibration;
• orbital;
• corner;
• renovators.

Belt sander for wood

Helps quickly remove large layers of material, polish boards, and sand places where parts fit.
These units have high power and allow you to quickly and efficiently cope with large areas, and the master must have professional skills in working with such a tool so as not to spoil the result.

Vibratory wood sander

The larger the area of ​​the working sole, the faster you can grind a particular area. Usually the sole is rectangular, but some models are equipped with a triangular wedge for working in hard-to-reach areas. The higher the vibration speed of the grinder, the lower the quality of grinding.

Eccentric (orbital) sander for wood

The eccentric CMM is designed for fine processing in the final stage of working with wooden objects.
The design of the orbital sander helps produce circular and translational movements of the sanding pad.
One of the varieties of eccentric sanders, the delta sander has a delta-shaped working surface, which makes it easier to work in hard-to-reach areas.

Angle grinders for wood

Angler grinders are very efficient in operation, thanks to the powerful motor and high rotation speed of the grinding disc.

Renovators for woodworking

An angle grinder cannot work with internal angles. Renovators (multi-tools) are more suitable for this.
The renovator can:

• Polish;
• create slots;
• clean walls, floors and ceilings of linoleum, tiles, paint, plaster.

Manufacturers are constantly working to increase the functionality of renovators. Depending on the model, the renovator can operate either from the mains or from a battery.

Where to buy a wood sander inexpensively

You can buy a wood sanding machine inexpensively in the Shuriki online store. A wood sander, the price of which will not break your budget, is already waiting for you!

Construction or restoration work requires the purchase of a tool for finishing wood (a wood grinder), but which model should you choose? It depends on its purpose, since the tool is multifunctional. The selection criteria are largely influenced by the characteristics of the surfaces being processed: their size or the complexity of the design with many hard-to-reach places. Equally important is the size of the budget allocated for restoration or construction, as well as the experience of the craftsman and his skills in working with tools for sanding wood.

If you need a sander for home use (minor repairs, hobbies), choose simple and quite budget models.

They are light and small in size. To process large volumes of construction or production work (for example, in a furniture workshop), it would be more successful to purchase powerful units.

The following types of woodworking sanders are distinguished:

• tape;
• ​vibration;
• ​eccentric;
• ​angular;
• ​renovator;
• ​brush.

Belt sander

It is beneficial to choose such a tool if you need to effectively remove large layers of material (for example, old paint), sand boards, process cut lines and accurately adjust the surfaces of parts.

These units are very powerful, and if the master does not have enough experience, then there is a danger of ruining the surface being treated. Working with a belt sander requires some skill. But with a little practice, you can quite easily, quickly and efficiently process a large area.

When choosing a grinder of this type, you need to make sure that you have the necessary equipment: models produced by different manufacturers are equipped with abrasive belts of various sizes.

Inexpensive models have a basic set of features:

1. Speed ​​control switch.
2. Thermal protection of the motor.
3. A nozzle for connecting a vacuum cleaner (or a dust collector).

Vibration sander

A vibrating machine is a tool for a more “delicate” effect on the surface of the wood. The work surface is often rectangular in shape, which makes it convenient for sanding corners.

The main criteria when choosing this particular type of machine are:

1. Dimensions of the working surface (sole). This parameter directly affects the speed of work performed.
2. Sole shape. The rectangular surface can be supplemented with a triangular wedge for working in hard-to-reach places.
3. The amplitude of the machine’s movements: as it increases, the processing speed increases. But this may affect the quality of grinding.
4. Method of fixing an abrasive surface. There are several possible options: clips, Velcro, a combined method.
5. Possibility of adjusting the speed of movement: it may be different for different wood.
6. A way to get rid of chips and dust.

The parameters of grinders that you should pay attention to in this case are:

1. Platform size (diagonal or triangle area).
2. Tool performance, which is directly related to the oscillation frequency (up to 2600 counts/min).
3. Weight (about 1 kg)
4. Power (most often from 300 to 200 W).

Random orbital sander

An eccentric or orbital machine processes the wood until it is completely polished.

The eccentric machine processes the wood until it is completely polished.

Difficult areas are processed in a different way, often manually. This design is distinguished by a complex trajectory of movement of the working surface: the sole of the machine makes rotational and oscillatory-orbital movements. Pneumatic models are most convenient to use.

This type of tool is the most expensive. Moreover, pneumatic models of grinders must be equipped with a high-performance compressor. This is not always possible for domestic use. Most often, such a tool is used in production.

If the shape of the surface is triangular (delta grinder), then such a tool is used if it is necessary to work in hard-to-reach places. This makes it possible to avoid manual sanding. The abrasive paper is attached to the base using Velcro, which makes it quick and easy to replace.

The speed of its work is very high. This model brings any detail to perfect smoothness, but it can only be used to work on large and even surfaces.

Additional devices

Angle grinders have high productivity, which is explained by the presence of a powerful drive and high speed of the equipment. However, a significant drawback of the model is the inability to process internal corners. Delta nozzles or renovators are more suitable for grinding them.

The renovator is similar to the delta modification of the vibration machine, but has significantly greater functionality.

The list of its capabilities includes:

• polishing and sanding wood and other materials;
• ​creating slots;
• ​cleaning walls and other surfaces from linoleum, tiles, etc.;
• local repairs of power structures and cladding.

A professional tool of this type is equipped with a warning device that notifies with sound signals of excessive load on the surface being processed. Depending on the volume of the surface being processed and the tasks assigned, the master may prefer a model with a two-handed grip. This is convenient if you need to work for a long time. The advantage of one-handed models is their compactness.

Moreover, manufacturers are constantly increasing the number of possible operations performed by the tool. Additional advantages of the renovator are its ability to work both from the network and from a battery, low power consumption, and a very affordable price. Brushing machines do not use an abrasive belt, but metal brushes. This type of tool is convenient for processing large surfaces. It is used to remove old coating.

The features of each unit make it effective in performing certain tasks:

1. The belt sander works well on large, flat surfaces, for example, voluminous parts of simple configuration. But this type of tool is not very convenient for processing small items.
2. Vibratory grinders have average productivity, are effective for processing parts of various shapes, do not leave marks, and are economical in energy consumption.
3. Eccentric models are good for achieving high quality processing: grinding or polishing.
4. Renovator or delta modification is a tool for designing furniture. It is also used for interior finishing work with wooden elements.

Such units cannot operate continuously; operation will have to be stopped every 15 minutes. The most universal model is considered to be a belt sander. It is suitable for processing not only wood, but also other types of surfaces (plastic, metal), and can be useful for both professionals and amateur craftsmen. Expensive professional grinders can operate non-stop for a full working day. They also have the function of centering the abrasive belt, which saves material.

To make the work easier, the master can equip the grinding machine with a stand on which the tool is attached. When performing grinding, you can move, rotate, and guide the material itself, and not the heavy unit. If the work continues for a long time, then even if you have a relatively small machine, it is much easier to manipulate the workpiece.

Processing most types of wood, due to its not too dense structure, is not particularly difficult. But if you need to achieve high quality, prepare the material for subsequent coating (for example,), 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 help you not only understand that a good owner really needs a wood sander, but will also tell you how to choose it correctly.

They differ in design, principle of operation and precision of wood processing. Consequently, the specifics of the application. What exactly to choose, you will have to decide on your own, based on the purpose for which you are purchasing the power tool.

Belt type machines

Belt type sanders are the most common in everyday life. They can carry out rough processing not only of any wooden workpiece, but also of samples made of plastics and metals. Such machines will not be able to polish the surface to a mirror shine, but eliminating obvious defects and leveling the base with their help is not a problem. And quite quickly. All you need to do is install a belt with the optimal grain size.

Belt CMM device

Like any electric tool, it includes a low-power electric motor and an actuator in the form of rollers. An abrasive belt is stretched over them, forming a closed loop. When you turn on the sanding machine, the rollers begin to rotate and the “skin” begins to move. The quality of processing is determined mainly by the clamping force and the grain size of the installed blade.

What to evaluate when choosing

• Power of the grinding machine. For the “household tools” category, 1 kW is sufficient. More is unlikely to be needed.
• Speed ​​control range. The larger it is, the wider the scope of application of the grinder. Such grinding machines work with any type of “skin”, therefore, they are suitable for processing various materials - metals (rust removal, pre-polishing), wood (cleaning, cutting off remaining knots, and so on).
• Linear parameters of the tape (mm). For household models, the standard width is 76, but in terms of length there is a certain size range (standard) - 457, 533 and 610. The latest samples are larger, but with their help it is more convenient to process workpieces such as boards, logs, timber or decking with a large area.

If the CMM is needed only for “spot” work - leveling minor segments, smoothing the surface in certain areas, then you can get by with a machine with a 400 belt. Such models are cheaper.

• Centering mechanism. During operation, the tape constantly shifts (“leaves” the rollers), and it has to be periodically corrected. The presence of a special device greatly simplifies this task, since the adjustment is done automatically and you don’t have to waste time on it.

The starting price for belt sanders is 3,468 rubles.

Examples

“Makita” (series 9910K) - a power of 0.65 kW is enough to process not only wood, but also metals. The belt speed is not adjustable (270 rpm), so the scope of application is somewhat limited, although this is sufficient for domestic use. Parameters of the abrasive cloth (mm): width – 75, length – 450. Price – 9,180 rubles.

"Bosch" (PBS 75 A series)– power 0.7 kW, abrasive belt speed (76 x 530) 350 rpm, weight 3.2 kg. Price – 7,590 rubles.

Brush models

They are classified into a separate group, although this is just a type of tape CMM. The working tool is a brush mounted on a shaft, which does the roughest work.

What can you do with such models?

• Removal of foreign deposits (scale, rust, oxides).
• Removing a layer of old paint.
• Cleaning wooden surfaces (plank and parquet floors, external walls, etc.).

With certain skills, brush sanders are used to artificially age wood products.

What to evaluate when choosing

• What kind of “tool” can be equipped with – types and sizes of brushes and abrasive cloths.
• Weight. It must provide sufficient pressing force for the ball mill to the base being processed. Optimally – at least 4 kg.
• Shaft diameter. This parameter determines the maximum rotation speed, and therefore the quality of wood processing.

Price – from 6,490 rubles.

Examples

"Makita" (series 9741) - power 0.86 kW; brush diameter 13 mm; speed – up to 3,500; weight 4.2 kg. Price – 29,320 rubles.

"Makita" (AG1014P) - low-power equipment (1.4 kW) with a speed of up to 3,000. Weight - 3.3 kg. Accordingly, the price is lower - only 7,280 rubles.

Vibrating type CMM

Grinding machines of this type are used for finishing surfaces. It is advisable to purchase them when the quality of grinding is the determining factor. For example, when restoring furniture, before covering the wood with stain and varnish. Such work requires special care, since the smallest defects are clearly visible through the applied transparent layer.

A modification of the vibrating CMM is a machine with a delta-shaped working part. Its application is specific - processing wood in corners, recesses, grooves and the like, so they are rarely used in everyday life. But if the owner deals with wood processing all the time, then it’s worth paying attention.

What to evaluate when choosing

There are 2 main parameters:

• Speed. Similar to tape models - adjustment limits.
• Processing depth. Such machines are excellent for working with samples on the surface of which there are significant differences in height. For example, after drying the material, if it was organized in violation of technology.

The starting price of the models is from 1,650 rubles.

Examples

"DeWALT" (series D 26441)– sole 115 x 140 (mm); power 0.23 kW; stroke size 1.4 mm; Velcro clip. Price – 5,458 rubles.

"Metabo" (SR 2185 series)– abrasive 93 x 185; power 0.2 kW; platform stroke – 2 mm; fastening the working element with Velcro. Price – 7,390 rubles.

Eccentric sanders

If you need to bring the wood to a mirror shine, you should use exactly this model. But the scope of application is limited - only for surfaces with the correct geometry. If the base is curved, especially curly, this is not an option. We'll have to look for another method of grinding.

What to evaluate when choosing

• Power. For domestic use, up to 750 W is sufficient.
• Amplitude of oscillations. Optimally - from 5 to 7 mm.

Increasing these characteristics leads to an increase in the cost of the grinding machine. In fact, these are already professional models. It is up to the buyer to decide whether to choose them for the home or not.

• Fastening the working “tool”.

It will take more time to change the element, but the consumables are cheaper. These are the types of CMMs that are mainly purchased for domestic use.

The only plus is the speed of replacing the working element. Convenient - yes. There are more disadvantages - the cost of “consumables” is higher, and not every modification of them is suitable for a certain CMM model. You may have to search online and pay for shipping.

Price – from 2,190 rubles.

Examples

"Elitech" (MSE 0412E series)– power 0.4 kW; 125 mm disc; speed adjustment ranging from 6,000 to 13,000; amplitude – 2 mm; frequency from 12,000 to 26,000. There is a connection to a vacuum cleaner; power cord – 3 m. Price – 2,870 rubles.

"Makita" (BO5030K series)– 0.3 kW; disk 125; speed – 12,000; frequency – 24,000; amplitude – 5.5 mm. The CMM kit includes containers for collecting dust. Price – 6,290 rubles.

The question is far from idle, since the market is literally saturated with various models of wood sanders, and each is positioned as one of the best. What do you recommend?

When systematically using a sander for a variety of operations, it is worth focusing on time-tested brands - Makita, Bosch and DeWalt. A little more expensive, but they definitely won’t let you down even with intensive use.

If the owner picks up a CMM only occasionally, for short-term use, it is enough to purchase a model of the “Skil” or “Kress” brand. Among household-grade sanders, they have the largest number of positive reviews.

Practice shows that while the rules for choosing a grinding machine are generally clear to everyone, the same cannot be said about the criteria by which an abrasive blade is evaluated. It is this question that puzzles many.

What to look for

• Abrasive material. For most types of work, belts with zirconium grains are best suited. All rough surface cleaning is carried out with just such a cloth. But after processing, scratches remain on the wood that need to be leveled out. This is done with a tape containing aluminum oxide particles. Therefore, you need to purchase a kit - for basic processing and “finishing”.
• Grain density (pieces/inch). This parameter is related to the size of the abrasive granules. Grinding is carried out by sequential installation of belts. First - at 65, then - at 120.

Finishing (fine) sanding of wood is always carried out in the direction of the fibers, and rough sanding is carried out at an angle to them.

Dust removal from the work area is carried out in different ways. But from a practical point of view, it is not recommended to purchase sanding machines equipped with bags. Once the supply of containers runs out, problems will arise in purchasing them. Verified. It is better to choose a CMM that can be attached to a vacuum cleaner. Much more convenient.
