This single piece, cross-slit fibre disc offers excellent usage of the abrasive grain by means of an optimised layout. Low disc wear and optimised grain adhesion: This results in a long service life for the disc and fewer tool changes. These fibre discs are used together with a practical STF backing plate on angle grinding machines. Thanks to the self-sharpening effect of the innovative ceramic abrasive grain, this fibre disc always stays perfectly sharp. During use, ceramic particles break off and make space for new ones with sharp cutting edges. That is what allows this highly versatile tool to achieve very high stock removal with little force required, consistently over the tool service life and with impressive durability. Tool replacement is significantly reduced – lowering tool costs. Hardened surfaces, wear-resistant steels, scale and hard coatings, titanium alloys and reinforced weld seams are no problems and can be machined quickly. Regular testing of the fibre discs ensures a high degree of reliability.
