Tiger Ceramic 4.5 inch conical flap discs are designed for maximum performance when grinding aluminum, stainless steel and other hard-to-grind metals. A top coat protects high-value parts stainless steel parts from heat discolorization and also prevents loading on soft alloys like aluminum.
Ceramic grains utilize a crystalline structure that is designed with millions of fracture points that self-sharpen at a higher rate than other grains. The result is a high material removal rate, cool grinding, and reduced friction at less pressure which reduces operator fatigue.
The type 29 conical disc shape maximizes surface contact when grinding between 15° – 35° for aggressive stock removal on flat surfaces while the 40 grit abrasive grain is best for edge beveling, chamfering, weld grinding, and blending with a right angle grinder. This disc offers a metal 5/8″ – 11 nut that allows for quick changeovers and prevents the disc from sticking to the spindle. Top coated for cool grinding, protecting high-value parts from heat discoloration. Prevents loading on soft alloys like aluminum. Contaminant-free (contains less than 0.1% Fe, S, Cl). Conical disc shape maximizes surface contact for aggressive stock removal on flat surfaces. Ceramic alumina (CA) grains are self-sharpening micro-fracturing crystals that expose sharp edges, maintaining a high cut-rate for the life of the grain.
