Overview of the best grinders | Top Expert
Sanders are good for more than just smoothing lumber. Removing layers of paint, rough metalworking, fine-tuning surfaces before finishing work — this is an incomplete list of processes subject to a lucky grinder.
Along with models with the best performance, there is a wide range of amateur devices on the market, the parameters of which are somewhat inferior to the leaders in the segment, but this is more than offset by a more affordable cost.
The best belt sanders
A powerful, and heavy enough grinder so that during operation it does not exert much effort to press against the surface. It copes well with large volumes, but for processing small areas (bookshelves, etc.), you should choose another tool — in such cases it is almost impossible to complete the task with this tape machine. Pleased with a decent length of the power cord — 4 meters, which sometimes allows you to do without carrying (for example, when sanding wood parquet in a room).
For more comfortable working conditions, there is a dust collector, instead of which you can connect the suction hose of a construction vacuum cleaner. The smart design of the grinder ensures fast removal of the belt and armature brushes on the engine — these operations take a minimum of time, which is highly appreciated by professional builders. You can also adjust the speed of rotation of the tape — there are five modes in total. In addition, the trigger has a locking button and with long uninterrupted operation, and the Makita 9404 tolerates it perfectly, there is no need to hold it all the time.

At idle, the belt speed can vary from 240 to 450 meters per minute. You can adjust the speed by simply manipulating the special adjusting wheel. You can change the tape quite easily and quickly even without a special tool. The power of the motor, combined with the precise running of the belt, results in high quality sanding with minimal effort. The speed of the belt can be controlled by high-tech automation controlled by full-wave electronics Vario-Tacho-Constamatic. At the same time, on different materials, when the load changes, the speed remains unchanged. For the most accurate guidance of the tool, an additional handle is provided in the design.
The functionality also allows literally in a matter of minutes or even seconds to readjust the machine for stationary operation. At the same time, the longitudinal stop «comes into play», which takes on the function of ensuring the accuracy of the workpiece. To collect the removed material, a standard antistatic dust bag or an external universal vacuum cleaner can be used. The delivery set of the device includes, in addition to the machine itself, an antistatic dust collector, a hex wrench, an additional handle, an adapter for connecting a vacuum cleaner, a platform for stationary installation, and a longitudinal stop.
Hammer LSM 1000 PREMIUM
Hammer LSM 1000 PREMIUM
Hammer LSM 1000 PREMIUM is the heaviest — almost 7 kg, which is an absolute record among grinding tools in this category. The impressive weight is largely due to the metal case, which in itself is quite rare — it is difficult to disable it with a normal fall (and every user has had to drop the tool at least once). Previously, there was a dust collector in the kit, but it clogged very quickly — the device is powerful (1200 W) and works efficiently.
Because of this, the manufacturer recommends connecting the tool to a construction vacuum cleaner — this method also allows you to work clean and not use respiratory protection. In addition, the tape machine has a speed control — with its help you can set the unit to remove the varnish layer from the parquet, or sand unprepared wooden panels. With all the obvious advantages of the model, users do not at all consider its cost to be overpriced, rather, on the contrary, it is deservedly positioned as one of the best machines and, in terms of its characteristics and quality, is not much inferior to more expensive professional units.
The presented model of the Status BS75 grinder is designed for cleaning and subsequent finishing of various surfaces. This tool belongs to the tape type and has a rather impressive power for the budget segment — 900 watts. The length of the belt is 533 mm, and the speed of its movement can reach 430 m/min with the possibility of adjustment. For greater reliability while operating the Status BS75 machine, an additional handle is provided.
In the process of working with wood or any other material, order will be maintained at the workplace. To do this, the Status BS75 grinder has a dust container, instead of which it can be connected to a vacuum cleaner. The package also includes a frame for adjusting the depth of polishing. With the help of special clamps, this machine can be used stationary (tape up).
The best brush sanders
Unlike most brush grinders, Makita 9741 compares favorably with the fact that the abrasive drum is completely covered by the casing, which certainly makes the professional tool safer. High performance is what owners value this device most of all. He copes well with 20 sq. meters of floor (from different types of wood) for a couple of hours. Yes, edges and corners are inaccessible to him, but this grinding unit “clicks at once” for large volumes. At the same time, the engine power is nothing at all — 860 watts.
The width of the consumable is 100 X 120 mm. The kit includes a nylon brush, with which you can effectively reveal the texture on the treated wood. For brushing, you need a cylinder with a pile of brass or steel. There is an outlet for the dust collector (it is not included in the kit), but given the performance of this “monster”, it is completely unnecessary — it would be more correct to immediately attach it to a construction vacuum cleaner. The reliability of the tool is best indicated by the presence of a manufacturer’s warranty — it is given for a year, which is more than enough for a grinder of this level.
High performance brush sander Sturm! AG1014P is perfect for processing and professional surface cleaning from various kinds of contaminants. Thanks to the function that allows you to adjust the number of revolutions in the range of 1000-3000 rpm, this machine can be used for a wide variety of surfaces made of wood, plastic, metal, etc. The tool needs such consumables as a sanding brush.

An important advantage of the model is an easy penetration into hard-to-reach areas thanks to a rectangular pad measuring 115×229 mm, which extends beyond the contours of the case. For exactly the same reason, it is easy to process the surface with it in the minimum proximity to an insurmountable obstacle — for example, for grinding the floor directly against the wall or vice versa.
To collect dust, you can use the supplied dust collector or connect the machine to an external vacuum cleaner through an outlet. It is important to remember that in this model dust removal is carried out through the support frame, which means that you must not forget to follow the strict coincidence of the technological holes on the pad and sanding sheets. In general, the 9046 model finds the most positive reaction from buyers, who characterize it as reliable, durable and trouble-free. Even with intensive use, it does not require frequent maintenance.
