Grinding Paper – Best Solution for Grinding of Soft Materials

Contrary to most other commercially available grinding papers that are SiC based, Rhaco Grit P120-P320 is based on Al 2 O 3 which means that the lifetime is 2-3 times longer providing at least 100% higher material removal. Rhaco Grit P400-P1200 provides great edge retention and planeness because it is produced on a thin, flat grinding paper ...
