Review of the 15 best sanders for working with wood and metal

Sanders are good for more than just smoothing lumber. Removing layers of paint, rough processing of metal, fine finishing of surfaces before finishing work - this is an incomplete list of processes available to the lucky person with a grinder.

In this article we offer you:

1. consider the rating of grinding machines;
2. determine the range of proposed work;
3. choose the appropriate equipment.

Table of main selection criteria

Before you begin to familiarize yourself with the capabilities of the most popular models, you should remember two facts:

1. Each variety has a fairly narrow range of applications. Multifunctionality is characteristic only of renovators, but the volume of work that MFPs can handle does not allow them to be considered as the main tool, even for an enthusiastic amateur;
2. The opinion that an angle grinder (angle grinder) in capable hands can cope with any task (from removing paint to sharpening drills and saw chains) is not supported by reliable facts. In 99 cases out of 100, such “versatility” is associated with a violation of safety regulations.

Classification of grinding tools according to operating principle

Belt grinding mills (rough grinding of lumber after or instead of sharpening; removal of relief, cleaning of sheet metal).

Bort BBS-801N

at prices starting from RUB 3,326.

The budget belt model Bort BBS-801N with an adjustable additional handle is designed for rough cleaning and longitudinal sanding of coatings over large areas. Adjusting the rotation speed of the abrasive belt allows you to select the optimal mode for working with wood, plastic and metal. The design of the tool (an opening cover above the driven shaft) provides the ability to process cavities whose depth does not exceed 80 mm. The driven shaft protruding beyond the housing makes it possible to process surfaces limited by straight and turned corners. Despite the presence of a locking start key and a powerful motor, the tool is not intended for intensive use.

• A 10-minute break after half an hour of continuous work,
• periodic blowing of air ducts,
• timely maintenance,

are the guarantor of many years of trouble-free operation of the Bort BBS-801N model in conditions of non-professional use.

Classification of tools

In stores you can find grinding machines designed for household or professional needs. Each type has its own characteristics, which it is advisable to know about before purchasing.

Household

A household tool is chosen if you have to work with it irregularly. On average, CMMs are designed to operate for 20 hours per month from 220 V, which is much less when compared with professional samples.

Every 15 minutes of working with a household grinder, you must stop for 10-15 minutes, otherwise there is a risk of damaging the engine.

Attention! Manufacturers do not recommend working with the device for more than 3 hours during the day. If you need more, you will have to abandon the household device in favor of a more serious one.

The advantages of a household unit are its affordable price and ease of operation.

Professional

This type of tool is designed to work continuously for a long time. Typically, professional grinding machines are used in production. They are much more reliable than household ones because they are made from higher quality materials.

The equipment is designed for multi-shift work in intensive mode. The devices are quite large, since a more powerful motor is located inside the case.

When developing a grinding machine for professional use, not only production requirements are taken into account, but also criteria such as convenience and safety. Therefore, manufacturers produce equipment that creates a minimum of vibration.

Makita 9911

at prices starting from RUB 7,699.

Light weight and low power do not prevent the Makita 9911 from stripping coatings, sanding uneven surfaces, and polishing paintwork. Obtaining a high-quality result on any surface is made possible thanks to the smooth adjustment of the belt rotation speed. Convenience of working with long construction moldings is provided by:

• location of controls,
• ergonomic handle at the front of the sander,
• autonomous dust collector,
• simple mechanism for tensioning the tape.

The simplicity of the equipment does not affect the results of the CMM operation.
Provided that the tool is correctly adjusted (speed, shaft alignment) before starting work, productivity and quality will be at a professional level. Main technical characteristics of Makita 9911

Criterias of choice

To select the optimal model , you need to clearly define the area of ​​its future application and likely loads. In this case, you can get the best price/quality .

When choosing a grinder, pay attention to the availability of spare carbon brushes, which are among the first to fail

in choosing for your home or summer cottage - most likely, it will be overly powerful and contain unnecessary options. When purchasing, you need to pay attention to the following:

• Power . The higher it is, the faster the work will be completed. The power of grinders ranges from 500 W to 1.2 kW . 500-700 W is sufficient ; professionals should choose more powerful tools. You will have to pay for productivity with greater weight and price of the tool.
• Working belt dimensions . It can have different widths and lengths. The larger these parameters, the greater the performance. Professional models usually have a working surface width of 100 cm .
• Tool weight . The weight of the grinding machine usually does not exceed 7 kg .

When purchasing, you should pay attention to the availability of additional options.

Interskol PShM-32/130

at prices starting from RUB 1,618.

Compact tool PShM-32/130 with a delta-shaped sole for fine grinding at corner joints and on a relief surface (a paneled door made of solid wood, for example). Access to any corner is ensured by the tapered sole. The combination of minimal amplitude and low vibration frequency of the platform guarantees professional quality:

• when removing single-layer coatings (coarse-grain consumables are needed);
• when sanding smooth changes (fine sandpaper will be required);
• when dry polishing protective layers of paints and varnishes (with a suitable soft nozzle).

The connection of the consumable to the sole is made using the Velcro system (also known as Velcro), which securely holds the abrasive sheet during operation.
If you do not have the necessary consumables, they can be cut out of sandpaper with a felt layer. For full operation of the built-in dust removal system, it is necessary to make holes in the self-cut sheets according to the sole template. The main thing is not to subject this amateur tool to constant intense loads, and to blow all holes with compressed air after finishing work. Main technical characteristics of PShM-32/130

Watch a short video review revealing the features of the configuration and design of the PShM-32/130 model:

Belt sander

The second name for such equipment is an endless machine. It received its second name because of the sandpaper, which, like a tape, is put on the rollers.

This type of machine will allow you to grind products to medium cleanliness. This will be enough for products that will then be painted.

The advantages include:

1. Performance.
2. Possibility of processing surfaces located near the wall.

The disadvantages of such machines include the ability of the tape tool to leave deep scratches on the wood. It will be possible to remove it only using stepwise technology, which in turn will only complicate the grinding process. Such a tool weighs quite a lot, so it is difficult to work with it in weight.

Interskol PShM-115/300E

Which sander is better to choose - eccentric or vibrating?

Buying a vibrating or eccentric sander for your home depends on your goals. Both devices allow you to remove old paintwork, process a car body, polish furniture, doors and other workpieces.

At the same time, surface grinding models are more often used for rough grinding of wide surfaces. The degree of accuracy of polishing largely depends on the abrasive installed on the soleplate. But in general, machines with a rectangular platform provide sloppy rough cleaning. With their help, it is convenient to remove old coatings in order to later achieve perfect smoothness using other devices.

Sanders with a round attachment provide a finer polish. They are more often used for finishing work, when the material needs to be not only cleaned, but made as smooth as possible.

Whether an eccentric sander or a vibration sander is better depends also on the characteristics of the part being polished. Surface grinding models with a smooth rectangular sole are well suited for processing shelves, steps, window frames and door panels.

If the surface is curved or has decorative elements, then it is more convenient to use an orbital sander to polish it. The rounded sole allows you to process radii and small parts of non-standard shapes without unnecessary difficulties.

The scope of application for surface grinders is generally narrower than for orbital grinders.

If a grinding unit is needed for professional use, then it is better to buy models of both types at the same time. In this case, the devices can be used alternately - for rough stripping and final stripping.

Makita 3711

at prices starting from RUB 3,970.

Thanks to an effective system for removing dust from the work area and the presence of electronic adjustment of the oscillation frequency, the Makita 3711 model is deservedly popular among professionals.
It is difficult for an amateur to appreciate the potential of the Makita 3711. After all, after processing unassembled joinery, another device will be needed to clean the internal corners (its own 2 mm stroke does not allow working in the corners of three planes). Therefore, the combination of vibration amplitude, the area of ​​the surface being processed, and the variable rate of vibration of the sole determine the narrow profile of the tool. It is designed for fine work with dissimilar materials, without volume restrictions. Main technical characteristics of Makita 3711

Watch a short video review of the Makita 3711 sander:

Random orbital sanders (preparation for painting, intermediate sanding and polishing of plastic, metal and wood).

What is the difference between an eccentric sander and a vibrating sander?

Both types of sanders are designed for the same purpose - processing and polishing wooden and metal surfaces. But there are important design differences between the units.

Eccentric machines, also called orbital, are equipped with an eccentric, which makes it possible to perform reciprocating or circular movements. The power of such units averages 170-750 W. They are used for cleaning, sanding and polishing parquet, furniture, and car bodies.

The round working attachment of the grinder allows the unit to be used for profile or curved parts

Vibrating devices, also known as surface grinders, are equipped with a rectangular platform with mounts for an abrasive blade. During operation, it is necessary to perform reciprocating movements with the apparatus to level the material. The grinding device is suitable for polishing wood and metal, plastic and stone, composites.

Attention! To achieve more accurate grinding when using a grinding machine, you need to move it at high speed, but with a small amplitude.

Thus, the difference between the tools lies mainly in the shape of the working attachment. Due to their design features, PSMs and orbital machines demonstrate different results when used.

AEG EX 150 ES

at prices starting from RUB 8,683.

AEG EX 150 ES is one of the universal sanders that has:

• vibration intensity adjustment,
• 2 vibration amplitude options,
• the ability to connect a bag or vacuum cleaner to the dust removal system;

Simplicity and reliability in use thanks to the Velcro abrasive fastening, durable plastic and molded base of the sole, as well as dust-proof controls. When an amateur simply uses a tool for a long time and gets an acceptable result, then professionals use the potential consciously, because they know that:

• “strangling” this grinder is not easy (the stabilization system instantly recognizes even insignificant pressure and regulates engine speed, preventing equipment wear);
• smooth start, sole brake eliminates damage to the surface being treated
• Properly implemented dust removal prevents premature wear of the working parts of the tool.

Angle grinder

Few people know, but with the help of a grinder you can sand wood. It copes best with rough sanding. The grinder is productive and works quickly on large areas of wood.

Ideal surfaces for grinding are floors, walls, log houses. The disadvantages of this angle grinder include the fact that we will not get a perfectly flat surface after grinding.

• In a hardware store you can easily find special attachments for grinders that are designed for sanding wood.
• It is recommended to use petal or disc-shaped wheels (the grain size of the sandpaper may vary).
• With this design, the working surface will be located behind a protective casing, which means it is safe to work in such conditions in any direction.
• If the product has protruding nail heads and screws, try to move the tool carefully. If possible, avoid these areas.

If you change only the grinding wheels on one tool, you can perform different grinding (from coarse to intermediate). In terms of time, it will take less than using another grinder.

How to choose the right grinding machine and what characteristics to pay attention to?

Types of grinding machines

Due to the fact that a large number of building structures, furniture, interior items and interior decoration elements are made from wood, the possibilities for using sanding machines are quite varied. This is precisely the reason for the presence of different types of this tool, differing in design and working using different consumables.

Tape models

This type of sander is used when it is necessary to perform rough processing of a surface made of wood. The main element of belt grinding machines is a belt made of abrasive materials and closed in a ring.

The tape is placed on rollers, which are driven into rotation by an electric motor, which is transmitted to the rotational and translational motion of the belt. The belt is positioned in such a way that, when rotated, it affects the material being processed over an area equal to the size of the sole of a specific model of the device. The main elements of a belt sander for wood For convenient use, the tool body is equipped with a front and rear handle, as well as a dust collector that collects waste generated during operation. The advantages of grinders of this type are high performance, functionality and a wide range of applications, allowing them to be used for:

• processing of rough surfaces, without their preliminary preparation;
• leveling and giving the desired shape to processed workpieces and assemblies made of wood;
• adjustment of various mating elements (corners, cutting lines, roundings, etc.) included in the composition of wooden products.

Disadvantages include:

• inability to process workpieces in internal corners and hard-to-reach places;
• heavy weight, making it difficult to use the tool “in weight”;
• significant noise level during operation.

Brush grinders

The operating principle of brush sanders is similar to belt-type devices. The only difference is that instead of an abrasive belt, a special brush is used, driven into rotation by the shaft of an electric motor.

The advantages of this type are:

• the ability to process a large area per unit of time;
• use of wooden products (furniture, decorative elements and structures) during “aging”.

The disadvantage is the narrow range of use.

Vibration models

Vibratory sanders are used to perform “soft” processing of wood products. Externally, grinders of this type are similar to their belt counterparts, with the only difference being that the working surface is not made of a belt, but in the form of an abrasive sheet of a certain shape. The abrasive is made from various materials and is fixed on the working platform of the device.

The shape of the abrasive material can be rectangular or triangular, depending on the model of the device. The operation of devices of this type is based on the movement of an abrasive material mounted on a movable platform. The movement is performed “back and forth” with a small amplitude and simultaneous high-frequency vibration. The abrasive is attached to the platform using clips or Velcro, which depends on the brand and class of the tool.

The quality of surface treatment depends on the technical characteristics of the device, as well as the type of abrasive materials used. The advantages of grinding machines of this type are:

• the ability to perform finishing processing of flat wooden products and structures;
• it is possible to process large areas per unit of time (productivity);
• low noise level during operation;
• the presence of different types of abrasive materials used.

The main disadvantage is the need for careful preparation of the surface before use, because... the ingress of foreign objects (grains of sand, sawdust, etc.) provokes the creation of “lambs” on the surface being treated.

Orbital (eccentric) sanders

Eccentric machines are used for polishing wooden surfaces. The main working element of this type of machine is a round sole, onto which special discs made of sandpaper are attached.

The operation of this type of grinder is based on the rotational movement of a disk mounted on a platform, which is driven into rotation by an electric motor. And at the same time, movement along the workpiece being processed is performed by a person. When processing material, the movements created by humans appear in the form of a spiral or orbit, which is why this type of sander is called orbital. Their advantages are:

• possibility of use on surfaces located in different planes of space (curved, profile, etc.);
• low weight allows you to work “on weight”;
• the presence of various abrasives allows it to be used both for polishing and other types of wood processing (rough, intermediate).

The disadvantages are:

• the round shape of the discs used does not allow processing in the inner corners of the product;
• When processing the surface, an area of ​​uncertain grinding is formed along the edge of the disk, which creates difficulties when completing work in hard-to-reach places.

Angle grinder

An angle grinder (angle grinder), or “grinder”, is known to everyone - it is a universal tool used in processing various materials: metal, plastic, wood. In woodworking, the main use is roughing and sanding.

To expand the functionality of an angle grinder when processing wood, special attachments and wheels are used that are mounted on its shaft: petal and disc wheels, as well as discs made of sandpaper. The advantages of using it when working with wood are:

• high performance;
• ease of use and maintenance.

Flaws:

• low quality of processing, unacceptable for furniture and carpentry;
• When working with discs made of sandpaper, they quickly become clogged and require replacement.

What characteristics should you look for when choosing a grinder?

Any hand-held electric tool has criteria that determine the parameters for its selection. For grinding machines, the general selection criteria are:

1. Electrical power – the performance of the tool depends on it.
2. The method of connection to the energy source (cord, battery), and if there is a cord, its length.
3. Ease of use - depends on the type of materials used and finishing elements (rubber handles, handles, etc.), as well as the location of the handles on the product body.
4. The weight of the tool – the mode of use depends on it, as well as the ability to work “in weight”.
5. Availability of automation and protection systems - soft start and protection against short circuit currents.
6. Possibility of adjusting speed modes - drive speed and abrasive tool speed.
7. Possibility of connecting to a vacuum cleaner or dust storage container.

When choosing belt-type models, in addition to the above criteria, you should pay attention to:

• length and width of the tape;
• type of belt centering mechanism (manual or automatic);
• presence of a brake;
• shape and the presence of an additional handle for ease of use.

When choosing orbital-type models, you need to pay attention to the following nuances:

• sole diameter;
• eccentricity value;
• presence of braking function.

When choosing vibration devices, you should pay attention to:

• shape and size of the sole;
• method of fastening the abrasive material;
• amplitude of the sole stroke.
