Premium Triangle Ceramic Resin Fibre Discs, 5in x 7/8, 25PK

C-PRIME PLUS offers improvement in abrasive grain manufacturing technology that results in a much finer crystalized structure. The unique mineral structure provides resin fibre discs with longer life and more aggressive grains in addition to improved self-sharpening features compared to traditional ceramic products.New Ceramic grain improvements include a higher metal removal rate at faster cutting speeds with a low grinding temperature and less friction.C-PRIME ceramic resin fibre discs offered with a top sized grinding aid. This design feature keeps the disc cool while grinding hard materials as well as Aluminum.Ceramic grain breaks down with much less pressure than Zirconia discs and thus reduce heat damage.
