Long-term compactgrain with a very open coating on a flexible polyester backing with continuous self-sharpening effect. KK770J is characterised by a consistent, very high stock removal with even surface roughness. It has a long service life when used for wide or long belt applications with low pressure.
- Long-term abrasive with continual self-sharpening effect achieves extremely long service life
- Reduction of grinding costs through lower tool consumption and fewer tool changes
- For uniform workpiece surfaces and surface roughnesses with constant stock removal
- Achieves particularly long service lives for stroke grinding applications with low contact pressure
