Plastic Grinding Chips

These high-quality grinding chips offer high stock removal rates and a fine surface finish. Their soft bond prevents any hardening of pitting of the workpiece surface. Plastic bonded grinding chips with a low density and a soft substrate are mainly used for the grinding and fine grinding of precious metals.
