Which sander to choose for the home
How to choose the right sander for your DIY project
Main selection criteria
Which grinder to choose? It is recommended to pay attention to such criteria.
For belt sanders, the equipment, an abrasive belt glued in the form of an endless ring, moves in one direction along two end rollers, one is leading, the second rotates freely. Linear grinding and high speed of movement of the abrasive provides high productivity, but at the same time requires increased control over the grinding process. LShM weigh up to 7 kg, and the power of the electric motor varies from 500 to 1500 W.
The three main standards of belt sanders are distinguished by the length of the sanding belt: 457 mm, 533 mm, 610 mm.
Belt sanders are suitable for rough sanding of surfaces made of wood, metal, plastic, mineral building materials. Often used when removing old paint or varnish, leveling putty. Due to its high productivity, large amounts of material are quickly removed, and in combination with coarse grit, the belt sander can function as an electric planer. The quality of grinding is not the best indicator of this tool, often during processing cavities and scratches appear. Effective for sanding glued panels and processing convex parts. Models available with the ability to work upside down, stationary.
This tool is not suitable for delicate sanding and requires special control when working. It can leave indentations in the material and, due to the specifics of the sole, belt sanders do not grind in the corners. High noise level and frequent clogging of the dust extractor are the disadvantages of this tool.
Making a choice
Having decided on the task and type, we make a choice in favor of a specific model of the grinder. If you have to work with the tool on weight, with outstretched arms, you need to pay attention to the dimensions and weight of the grinder. It is better to make the choice in favor of a light, compact, faster machine, albeit less powerful. If the work will be mainly on the workbench, choose a machine with a higher weight, more powerful. It does not hurt to turn the machine in your hands before buying, to understand how comfortable the handles are for you, whether the switches are conveniently located, how quickly and easily the equipment changes. Check the moving parts for play, visually inspect the body of the machine, look at the accuracy of the fit of the parts. Turn it on, at least when idling, to assess the level of noise and vibration. Inquire in advance about the availability and cost of consumables and equipment, such as a spare sole.

Angle grinder (angle grinder or angle grinder)
Such a tool is designed for processing stone, metal, ceramics and concrete. The design of the angle grinder assumes the location of the working shaft at an angle to the plane of the electric motor. Using a special abrasive disc of an angle grinder, they successfully eliminate corrosion, cut ceramic tiles, clean welds.
How to choose a grinder? There are the following main types of grinders.
The sander is classified into a large number of types, most of which can have a dust collector, or designed to work in conjunction with a construction vacuum cleaner or have another additional function. By the nature of the movement of the working body, such a tool can be surface grinding or rotary. Rotary tools use abrasive wheels of different diameters and shapes. In surface grinding units, a grinding sandpaper is used as a working body, which performs a plane-parallel or orbital movement in relation to the surface to be treated.
The relevance of using the tool
The use of a grinding type tool in repair and construction is becoming more and more relevant. And that’s why.
Firstly, the requirements for the quality of planes when performing modern finishing works using the latest materials have grown by orders of magnitude.
They also strive for three-layer finishing coatings, and if the base is insufficiently worked out, the work cannot be done efficiently. All surface imperfections appear many times.
Therefore, the planes to be processed must be absolutely smooth and even. Even sheet materials with a decorative layer often have to be joined, after which embedding / filling, sealing of seams and then grinding is performed.
And in all these cases, the quality of the final result is determined by the quality of grinding, so it is worth buying high-quality grinding discs (wheels) for your tool.
But we will only talk about which grinder to choose, the consumables for the tool should be selected in accordance with the specific requirements for surface treatment.
Which grinder to choose
Sometimes, in the process of home renovation, there is a need for a comprehensive preparation of various surfaces for applying coloring compositions or varnishes. At the same time, manual processing, as you understand, can take a lot of time and effort, in addition, it may not be as high-quality as needed. A sander can help in solving these problems. And in this short article we will tell you which grinder to choose for various tasks and what types of such tools exist.
To age a wooden surface, sand, remove old paint, remove rust stains, sand putty, grind off burrs, process plastic structures and even polish a stone. all these and many other operations are within the power of a modern grinding tool.
Probably, you have seen the process of working with a typewriter more than once and it is obvious that the use of a tool can significantly save time.
Which grinder to choose
From a wide variety of models, there are three main types of grinders:
- orbital (eccentric);
- vibration (surface grinding);
Each of the named models in these three categories is designed for a specific Spectra job, with its own capabilities and limitations. from rough and fast processing to performing delicate finishing sanding. The “heavy artillery” includes belt grinders, which make it possible to quickly remove significant layers from large-sized planes. Surface grinding machines (PSHM), used mainly for finishing.
Eccentric grinders (ESHM) make it possible to have a surface close in quality to polished. In comparison with machines of vibration type EShM have a different configuration and a different principle of operation.
Making a choice
When choosing a grinder model, evaluate the specifics and scope of those tasks that you will have to solve. From this point of view, the most important selection criterion is the power of the tool. Thus, professional belt sanders with a simple and reliable design, a solid rotational speed of the abrasive and a low center of gravity can be recommended for professional work in large volumes.
Such models allow without any problems to remove a layer of the processed material up to several millimeters and perform a number of specific operations, including making an edge or rounding, removing old paint, rust, etc. Powerful belt sanders are able to efficiently and efficiently work with workpieces made of wood, metal, polymers, mineral building materials, etc.
We hope that this article will help you decide which grinder to choose despite the huge variety of models of this tool.
Which Sander When?
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.
Grinding machine classification
At the moment, there are four types of grinders, which differ in terms of application, design, operating principle and other criteria. The following types of grinding machines can be used for carpentry and joinery, as well as repair and construction works:
- LShM. belt grinders;
- VShM. vibration grinders;
- OShM. orbital sander;
- Delta sander.
The choice of the machine is directly influenced by the scale of the upcoming work (for home or professional use).
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 to advise?
With the systematic use of the grinder, for a variety of operations, it is worth focusing on the time-tested brands. “Makita”, “Bosch” and “DeWALT”. Somewhat more expensive, but they will definitely not let you down even with intensive use.
The best in the household series
Despite the shorter motor life, the household tool can handle flat and curved surfaces. Perform rough and fine grinding of concrete, plaster, putty. Polishing metal, plastic, glass, natural and artificial stone
The processing of workpieces using a belt sander (LSM) is carried out with a grinding (emery) sandpaper, which is pulled over the rollers. The principle of its operation is reminiscent of a plane. when the tool is moved forward with pressing on the surface of the workpiece, the moving abrasive blade cuts off the top layer of wood. The working depth depends on the grain size of the skin and the applied force.
LShM makes it easy to level a wooden surface by removing wood to a depth of several millimeters; to process the edge, incl. round it up; remove the old coating from wooden structures. It is not suitable for fine polishing. Household LShK use a sanding element with a width of 6-12 cm.The most common length of a sanding belt is 76 cm.
The advantages of the tool are a significant coverage area of the processed surface, the possibility of leveling and simultaneous grinding of rough surfaces. Disadvantages. work at high speeds leads to the appearance of defects, the inability to polish the surface.
What to look for
- Abrasive material. For most jobs, zirconia grained belts are best. All rough cleaning of the surface is carried out with just such a cloth. But after processing, scratches remain on the wood, which must be leveled. This is done with a tape of aluminum oxide particles. Therefore, you need to purchase a kit. for basic processing and “debugging”.
- Density of grains (pieces / inch). This parameter is related to the size of the abrasive grains. Grinding is performed by sequential installation of belts. First. by 65, then. by 120.
Finishing (fine) wood polishing is always carried out in the direction of the fibers, and coarse. at an angle to them.
Dust removal from the working area is done in different ways. But from a practical point of view, it is not recommended to purchase sander equipped with bags. As soon as the supply of containers runs out, there will be problems with their purchase. Checked. Better to choose a CMM that can be attached to a vacuum cleaner. Much more convenient.
Varieties of grinders
They differ in design, principle of operation and precision of wood processing. Consequently, and the specifics of the application. What exactly to choose will have to be decided independently, based on the purpose for which the power tool is purchased.
