Hook-and-loop fibre disc Ø 115 mm 35 pcs

Silicon carbide. For grinding harder stone. For hook-and-loop backing-pad with Velcro system.Ø 115 mm. Set of 35 hook-and-loop fiber discs assorted in 11 grit sizes from 40 to 1200 grit.

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

The fibre hook and loop disc set contains the following grits:

4 x grit 40
4 x grit 60
3 x grit 80
3 x grit 120
3 x grit 180

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.
