Random rotary sanders stand out for their versatility. Particularly suitable for rough and finish work, they are used for sanding and polishing as well as paint stripping on vehicle bodywork for example. Easy to handle and suitable for small or medium-sized surfaces. Speed control means the tool can be operated to suit the specific characteristics of the materials to be worked, for example, metals or composites.
Depending on the type of work to be performed, the rotation orbit or offset varies between 2.5 mm (finishing) and 10 mm (roughing), with 5 mm for versatility.
Some pneumatic random rotary sanders are supplied with interchangeable suction tips (typically 29 and 27 mm in diameter) for connection to dust extraction units. When sold as a kit, they are supplied with different sanding plates, as well as consumables. As a general rule, the discs are secured using a double-sided hook-and-loop "Velcro"™-type system. Depending on the professional rotary sander model chosen (pneumatic), rotations per minute (rpm) are often between 3500 and 10 000 rpm.
