V The arsenal of a home craftsman must necessarily have a sander for wood. It is difficult to do without this handy tool when repairing a house or apartment. Sanding and polishing wood floors, walls or furniture can take a lot of time and effort. The grinder will not only greatly facilitate the task, but will also help to do the job much better. What types of machines are there, for what purposes are they intended and how to choose the best tool?

The grinder will help to process any wooden surface for painting or varnishing

Grinding equipment is divided into several subspecies. They differ in principle of operation and design features.

Types of grinders:

  • tape - rough processing of wooden surfaces;
  • vibration - used for soft processing;
  • eccentric - designed for polishing;
  • delta sander - has a specific, triangular shape of the sole.

Belt sander for wood

These grinders are considered one of the most powerful tools. They help you to effortlessly handle large surfaces.


The surface processed with this tool becomes smooth and even. The typewriter tape is fixed on two rotating rollers. The speed of rotation of the tape depends on the power of the machine and can vary from seventy-five to five hundred revolutions per minute. The tool has the ability to adjust the speed.


The functionality of the device depends on the width and length of the tape. The craftsman needs to have a variety of grit abrasives on hand to use the roughing and finishing tools.

Helpful advice! When choosing a tape for a tool, you need to make sure that it is elastic, does not have uneven edges and has strong, perfect joints.

The set of grinders of this type includes a dust bag. It is fixed on the shaft and collects sawdust and wood dust.

Working with a tape machine requires some skill. Before starting work on an important part, it is worth practicing on test surfaces. The novice master should pay attention to the models, in the design of which there is a frame for controlling the depth of processing.


Vibrating sander

This device is needed for finishing and polishing the material. Such a device is used to process not only wood, but also metal, stone and plastic. The basic principle of the machine is forward-reverse motion at high speed and low amplitude.

Useful information! The larger the amplitude - the deeper the grinding, the smaller - the better it is.

The vibration sander for wood has a standard rectangular sole. In some models, there are removable work surfaces in the shape of a triangle, they are convenient for processing corner elements.

Two types of attachment are used to attach the abrasive material to the tool:

  • clamps - a reliable option for fastening any size;
  • Velcro - allows you to quickly and easily change the abrasive.

Vibrating machines, like belt vibrators, have adjustable speed and a dust collector. It is believed that a plastic bag, as opposed to a fabric one, is more effective. The main advantage of vibrating machines is that they help to process small parts and objects of complex shape (frames, railings, doors) with high quality.

Eccentric and deltas

The eccentric sander for wood has a round sole, which is attached with Velcro. They work with such a device, rotating around an axis or in an orbit. That is why sometimes in retail outlets this tool is called an orbital sander.

The principle of operation of the device is the simultaneous execution of rotational and reciprocating movements. Such machines do an excellent job with curved surfaces and perform grinding and high-quality polishing of any material. Differences in different models of eccentric tools in power and possible amplitude of work. Deltamashinka is a highly specialized device. It is designed for hard-to-reach areas and corner surfaces. As with all grinding devices, the quality of the device depends on its operating power.

Useful information! It is better for a novice master to purchase a device with an audible pressure indicator. It will avoid damage to the material.

The best manufacturers and models of grinders

It often happens that a wood sander, the price of which seems to be quite decent, actually has the same functions and settings as a cheaper device. How to make a choice in this situation?

It is better to purchase the tool from manufacturers who are known to a wide mass of consumers and have proven the reliability of their products. Most popular brands:

  • Makita;
  • Bosh;
  • DeWalt;
  • Interskol;
  • Hitachi;
  • Bison.

The tools from these firms are known for their performance and durability. All these advantages are combined with an acceptable price tag. Makita offers the largest range of belt sanders. The instruments are distinguished by excellent engine sealing.

Hitachi- a company with more than half a century of experience. Her premium tools are a great choice not only for the DIYer, but also for the professional.

Bosch also offers a large selection of grinding tools, experts recommend paying special attention to eccentric machines.

Domestic Bison and Interskol are famous for their reliability and ease of maintenance.

Comparative characteristics of the most popular models of grinders will help you make the right choice.

A sander can greatly facilitate the life of a home craftsman. With its help, you can easily remove old paintwork, rust, wipe off a layer of putty, and so on. The grinding process itself is a rather monotonous and time-consuming operation associated with a large amount of dust, therefore it is quite problematic to perform such work manually.

Grinding machines are not too expensive, there are several varieties - depending on the purpose, technology of work, and so on. We decided to start our rating of the best grinders with the main selection criteria, which cannot be done without.

What are the rules for choosing a sander?

One of the most productive designs is the belt model, in which an abrasive belt, glued in the form of a ring, acts as a working surface. It attaches to the corresponding end rollers and moves at high speed. Such machines are quite powerful, they are distinguished by good reliability and long service life. With the help of such a device, you can easily remove a layer of material several millimeters thick, it interacts well with materials of any nature.


Surface grinders are ideal for finishing coatings for subsequent processing. The working plane is quite large here, so such models are well suited for use over large areas, regardless of the nature of the material. One of the main advantages is good processing of corners - there will be no missing sections, which in the future will have to be passed manually.

Another widely used model is the orbital sander. The surface treated with such a device will be perfectly flat, without waves, scratches or grooves. The average power of such devices is in the range from 200 to 900 watts. One of the most important criteria for choosing a device is the sole area and its type, which will ensure the fineness of processing.

We included all these models in the rating, the choice of devices included in the review was based on user feedback, both home craftsmen and professional finishers. In addition, we paid attention to the value for money of the design so that it would be within the means of most of our readers. Now let's go directly to the review.

In conclusion, an interesting video

As you can see, the range of grinders on the market today is quite wide, so choosing the most suitable model is not too easy, as it might seem at first glance. We hope that our review will greatly facilitate this task for you. If you have any questions regarding the content of the review or about a particular model, then you are at your complete disposal to comment on our article.

Let's start with the classification - each variety has its pros and cons, its own specialization. If you need to process planes of a large area at a high speed, and at the same time does not even fit the ability to sharpen the same drill or chisel, choose belt sander, which, if desired, can be used as a sharpening machine. But keep in mind that not all models have the ability to attach on the side or upward with a tape! In addition, the high performance provided by a rapidly running belt in a circle will also require "straight-handedness" - by pushing or overexposing the machine in place, it is easy to "dig" an unevenness in an almost ideal plane. A couple more disadvantages are the complexity of the design, the presence of a belt drive and the need to buy ready-made belts of the required standard size.

Vibrating machines have a rectangular or "iron-like" (for working in corners) sole, rapidly oscillating back and forth with a certain amplitude. Such machines are simple in design (you can buy an amateur one inexpensively, without particularly risking reliability) and good in performance. For them, you can easily cut the sandpaper from the sheet yourself, especially if the manufacturer has added a device for punching holes in the sheets to the kit. Even a beginner will master such a machine quickly. But, if you do not plan to work with wood, it is still better to look aside. eccentric (orbital) machines- they are, of course, more complicated, and you will have to buy Velcro circles, but it is easier to ensure the cleanliness of the surface with an "orbit" (the circle does not "crawl" back and forth, but also turns during grinding), it is more convenient to work on bends. It is not for nothing that you will see just such cars in any body car service: here you have to constantly bring curved surfaces to zero. But for a tree that needs to be sanded along the grain, an eccentric machine is not suitable precisely because of the principle of operation, in the hands of carpenters there are only vibration "surface grinders".

In addition to the power, convenience and level of vibration that you need to pay attention to when choosing any power tool, be sure to make sure that there is good dust protection for the main components of the machine and especially in the efficiency of dust removal: it is not always possible to connect a vacuum cleaner, and it is simply dangerous to use some models of grinders without a respirator, so they throw a lot of dust into the air in the working area.

Sanding is one of the types of bodywork. Given the large surface area of ​​the body, it is ineffective to carry out them manually, therefore, labor automation is required. This article covers how to choose a sander.

Two classes of grinders

The choice of the device in question should be based primarily on its purpose. That is, you need to decide what the machine is for and which one is best suited. At the same time, they take into account what work is planned to be performed with its use and how much to use it. Based on these parameters, they choose between professional and household models.

Professional tool

The main difference between the named types is that the first grinders are designed for long, continuous operation in difficult conditions. Their high reliability and endurance are due to the fact that high quality materials are used in the production of such models. In addition, they are characterized by high power. This leads to a large mass and high cost of such tools. Professional sander parts include rollers, abrasive belts and attachments, bushings, undercarriages and more.

Household appliances

The main advantage of these options is cost. Although there are quite high-performance devices among them, their capabilities are still inferior to the characteristics of professional counterparts. However, for the needs of ordinary users, this should be sufficient. For the rare implementation of work, it is not advisable to purchase an expensive and complex device. However, it must be borne in mind that such grinders are capable of functioning for about 20 minutes, after which a break of the same duration is required. Moreover, for one-time work, you can rent a tool.

What to consider when choosing?

The choice of the design of the tool is carried out on the basis of the features of the work. This takes into account the type of material and surface. The flat surface is the easiest to process. Before choosing, you should look at reviews, video reviews, manufacturer ratings and model ratings. They can tell a lot about specific instrument models. Moreover, both the quality rating and the popularity rating are useful.

You also need to consider not only how much the tool itself costs, but also the cost of components and spare parts for grinders. The price of the content includes abrasive elements, such as sandpaper for a sander. Such equipment is used by a flat machine; other options require discs, brushes.

Classification

There are several types of grinders distinguished on the basis of their design.

Corner

Grinders of this design are the most widely used. They are called grinders. The popularity of such models is due to the fact that these grinders are universal. They are suitable not only for polishing and grinding surfaces made of various materials, but also for cutting and processing metal and stone.

When choosing such tools, you need to focus primarily on the power and diameter of the disc. Simple versions have a power of 600 - 1000 W, providing rotation speeds of up to 6000 rpm. They can be used for grinding, polishing and shallow cutting. For jobs such as cutting stone, you will need about 2,000 watts of grinders at the same rotational speed.

The diameter of the wheel is also important, however, manufacturers produce devices for standard sizes of abrasive elements, which simplifies the selection. They range from 115 to 230 mm. There are also two options for the diameter of the bore holes: 22 and 32 mm.

In addition, you should choose a grinding machine with a speed control, since devices that do not have this device are not capable of performing all types of grinding, but they are suitable for cutting various hard materials.

Direct

Such tools are used to carry out small jobs that require high precision. For example, they grind small surfaces like lintels and planks, as well as edges and corners. In addition, using specialized attachments, which are equipped with most of the grinding machines of this type, it is possible to cut various materials of small thickness and apply engraving.

Many straight grinders are lightweight and designed to be held with one hand. Another important design feature of this type of tools is the location of the spindle parallel to the body.

Tape

The main purpose of such tools is the primary treatment of large surfaces. So, with their use, they carry out rough grinding, leveling, roughing, removal of paintwork. Belt grinders are most in demand by professionals, although there are also household options.

The abrasive working element of this type of grinding machine is represented by an emery paper tape glued into a ring. Most of the tools are fitted with a belt width of 40-120 mm, although there are options with a width of less than 40 mm, designed for machining difficult surfaces. In any case, the working element rotates on two end rollers. You can learn more about the principle of operation of such tools from the video. Outwardly, they resemble an electric plane.

The large, flat working surface of the belt sander ensures maximum productivity. However, the quality of work is not high.

The main parameters of such devices are the speed of the belt, the presence of a dust collector and a soft start system.

Vibrating

Such machines are also called surface grinders. The flat model is used for the final pre-paint treatment of surfaces, as well as for the removal of sagging of paint and varnish material before re-painting. In addition, the flat sander is suitable for processing materials such as wood, metal, stone, plastic, composite materials.

The flat sander operates on the basis of the fact that the flat sole makes a reciprocating motion of high speed and small amplitude. You can clearly observe how a flat machine works in the video.

The main parameters that characterize the flat model are the power and amplitude of oscillations.

Eccentric (planetary, orbital)

Grinders of this type are versatile, that is, they have a wide range of applications. So, they are used for grinding, cleaning, polishing surfaces made of metal, plastic, wood, as well as for fine grinding. In addition, they are suitable for curved-convex curved surfaces.

The principle of functioning of eccentric instruments is that the working surface performs rotational and oscillatory movements. You can see how the pivot machine works in many videos. The main parameters of the devices under consideration are the vibration amplitude and power.

Brush

The name of this type of grinder is due to the fact that the abrasive element is represented by a metal brush. There are small, straight, single-handed options, as well as larger belt-like models with two metal brush rollers. They are convenient to use as a glass grinder.

Delta

This equipment is used for processing small parts and hard-to-reach places. According to the principle of operation, these devices are similar to vibrating instruments and differ from them by the outsole brought forward, similar in shape to the working surface of the iron, and smaller in size.

Polishing

Such grinders are used mainly for polishing metal. In addition, they can function with cutting discs. By design, these devices are very similar to angular ones.

Multifunctional

Multifunctional grinders combine vibration, polishing and delta grinders in the body. They are widely used in renovation and finishing works. Multifunctional grinders are versatile due to the possibility of changing attachments.

Rotary

This equipment is mainly used for stone grinding and polishing. The principle of their functioning consists in the rotation of the abrasive element around the vertical axis, which can be observed in the video. The rotary machine can be equipped with different discs for different jobs.

End

End grinders are mainly used for finishing work. This is because end grinders are well suited for grinding and polishing surfaces made of materials such as metal, granite, marble. End grinders are designed to be held with two hands.

Typically, the rotational speed of their working element is 5000 rpm, due to which the end grinders provide good processing quality.

Separately, mention should be made of glass grinders. In production, specialized machines are used. At home, even a drill equipped with special attachments can play the role of a glass grinder.
