Popularity rating
It is not difficult to make a rating of cordless angle grinders on the market. Making a comparison, it can be noted that there is a significant difference between professional and household appliances. There are several popular models among the market leaders.
Metabo WB LTX BL 125 Quick is equipped with a brushless motor, modern electronics for safe operation, charging indicators. The innovative LiHD battery holds a charge for a long time, being considered one of the best on the market, and has a swivel design. At the same time, 9000 rpm at idle speed is sufficient to demonstrate high performance.
- Milwaukee M18 CAG125XPDB-0 features a brushless motor, professional grade and modern filling. Batteries are usually offered to be purchased separately - the manufacturer claims a capacity of 5 A * h. Among the advantages are the presence of a filter, a quick-clamping nut for changing equipment, the presence of an additional handle in the configuration.
- DeWALT DCG 412 M2 is equipped with a protective bracket, a 4 A * h battery, during operation it develops up to 7000 rpm at idle speed. The model has an additional two-position handle, there is a start button lock.
As for straight machines for wood, here, when performing work, it is not the number of revolutions of the spindle that is of primary importance, but the ability of the equipment to cope with the tasks assigned to it. Straight angle grinder is intended for finishing the surface to the desired smoothness. Among its differences is the special shape of the body, reminiscent of the classic brace. The equipment is mounted in front, in a special socket, the range of possibilities depends on the status of the model - domestic or professional.
Cordless straight angle grinders for woodworking have a power of up to 800 W, while coping with the basic set of operations. For long-term sanding on a large area, it is better to choose a more powerful professional technique of 2000 W, which supports working with discs with a diameter of up to 150 mm. For precise processing of the material, small equipment will also be needed, the wider the choice of possibilities, the easier it will be to achieve the desired goal. Among the leading brands here are Metabo, Makita, Bosch.
In the next video, you will find an overview of the Makita BGD801Z cordless straight grinder.
How to use the grinder correctly
Features of using a belt sander
The belt sander is best suited for large, flat surfaces.
First of all, you need to put on the tape. The easiest way to do this is when the car is lying on its side. Having previously snapped off the mount, put on the tape, taking into account the direction of travel - indicated by the arrow on both the tape and on the rollers of the machine. This is necessary so that the seam on the tape is positioned correctly. Otherwise, the tape may either tear or damage the surface instead of sanding. Then click on the mount.
The tape in the car always moves in one direction, respectively, in the same direction you need to work with the tool - pressing it tightly to the surface, move it towards you. The wood with a belt sander must be processed along the grain. Otherwise, deep furrows may develop. It is not necessary to press unnecessarily on an already heavy tool - instead of increasing productivity, you can overheat and thereby damage the belt.
To expand the functionality of the belt sander, you can use the frame, stationary mounts (vise), corner stops. It is the tape tool that can be fixed in a stationary vise and move not it, but the surface to be processed (for example, a board, a block).Such a fastening of a tool for grinding small parts is especially important. Also, when the machine is stationary, it is very convenient to sharpen grooves and rounds.
Another way to use the band tool is when the machine is lying on its side. Its advantages are that a right angle is formed in this position.

When preparing the machine, pay attention to how dusty the job is expected to be. And if there can be a lot of dust, it is better to immediately connect the vacuum cleaner, since many models have such an opportunity
The work is relatively clean - a dust collector will do. A respirator will keep you healthy.
Important! During its operation, it is necessary to periodically check the dust collector and avoid overfilling. Otherwise, dust will go out from all the holes.
The abrasive disc is attached to the circular platform of the machine with Velcro - it is simply applied and pressed by hand. You just need to make sure that the holes on the disc line up with the dust holes on the platform.
When processing a plane with a machine, you need to firmly press the platform against it. You need to keep the machine level so that the platform does not press against the surface with its edge - otherwise there is a risk of ruining the surface with scars. In order not to remove unnecessary things, this is especially true for bodywork, it is better to often check the surface with your palm for roughness.
As you work, check the dustiness of the nozzle, change it in time so that the work does not go idle when the grain is "clogged" and the roughness is no longer peeled off.

There are many ways to use grinding machines. This is preparation for body painting, and floor treatment, and polishing of wooden parts (even children's toys), and even polishing. The result of the work, of course, depends on the skill, the perfection of the skills of the person
But no less important is the quality of the instrument, as well as how correctly it is selected and correctly used.
Good luck with your work!
How to choose a sander for your home - summing up
- The belt sander is extremely efficient and processes large surfaces very quickly. For example, this appliance can quickly remove a very thick layer of paint from wood surfaces. The design is characterized by a very high power rating. The machine is extremely easy to use and safe.
- The eccentric sander is a good quality tool used for sanding flat and rounded surfaces. These models have the highest accuracy. However, the outsole does not reach hard-to-reach places such as corners. The machine has a circular disc, oscillating and rotating at the same time, depending on the pressure. It is also easy to use, but requires a little more attention than oscillation. This instrument is held with both hands. Thanks to the combination of the two movements of the plate, the model is very efficient, fast, productive and, if used skillfully, leaves no visible sanding marks.
- The oscillating sander is used for large flat surfaces. If we've never sanded before, it's best to start with this device. It perfectly smoothes the surface, while its work depends on the thickness of the sandpaper. The machine is very easy to use and safe. It doesn't require special attention.
- Deltoid Grinder - Small triangular outsole makes it easier to work on surfaces inaccessible to large sanders. However, the small footprint also makes the model ineffective for large surfaces.
