Hook-and-loop fibre disc Ø 125 mm

Silicon carbide. For grinding harder stone. For hook-and-loop backing-pad with Velcro system. Ø 125 mm.

Sharp grit, only for harder types of stone, max. speed 7,500 rpm, corresponds to 45 m/s. Silicon carbide abrasives have a harder, more brittle grain than aluminium oxide abrasives. This makes them very suitable for sanding medium-hard to hard stone.

The following grit sizes are available:

Grit 40
Grit 60
Grit 80
Grit 120
Grit 180
Grit 220
Grit 320
Grit 400
Grit 600
Grit 800
Grit 1200

Hook-and-loop backing-pads with a Velcro system are extremely practical, as the grinding wheels can be changed quickly and easily. At the same time, they have a very good grip. To ensure that the hook-and-loop backing-pad retains its adhesive force for as long as possible, it is important to pay attention to both the speed of the machine and the pressure exerted on the machine when sanding. If the speed is too high and the pressure too great, high temperatures can occur, causing the plastic loops of the hook and loop disc to burn, especially at the edge. As a result, the hook-and-loop sanding discs have less and less grip on the hook-and-loop backing-pad. Depending on the type of stone, excessively high temperatures can also cause grinding damage to the stone or, in the case of woodworking, to the wood.
