CGW’s C3 ceramic flap discs are made from an aggressive, self-sharpening ceramic grain and a cooling grinding aid to increase disc life on hard-to-grind, heat sensitive materials, the company says. The discs provide contaminate-free results in stainless steel applications and can also be used on steel and titanium. The flap discs are available in regular and extra-large thickness and with 4.5", 5" and 7" diameters. Grit sizes include 36, 40, 60, and 80, and arbor holes are either 7/8" or 5/8-11. For added strength on rough edge applications, the discs feature a hybrid, four-degree compressed and compacted flap configuration.
Flap disc lines include premium Z3 (zirconia grain), Z-Thru (zirconia grain; transparent grinding zone), A3 (aluminum oxide grain), aluminum cutting and silicon carbide. Flap discs can be used for both rough grinding and finishing applications.
