3M ZD4Q400 4" 400X Grit QRS Mount Flexible Diamond Disc

C.R. LAURENCE ZD4Q400 CRL 3M 4" 400X Grit QRS Mount Flexible Diamond Disc. The CRL 3MT Diamond Disc offers tremendous life compared to a standard silicon carbide disc. In addition, the edge quality is consistent throughout the life of the disc. This is because diamonds wear much slower than silicon carbide. Since diamonds cut rather than scratch like sandpaper, less pressure is required to accomplish the same material removal. Disc life and finish will always be improved when used with water. Supply the water by using a spray bottle or spray delivery system for best results. If used dry, wear appropriate dust protection equipment to guard against health hazards..
