Weiler Abrasives 4-1/2" Tiger Ceramic Abrasive Flap Disc, Conical (TY29), Phenolic Back,80C, 5/8"-11 UNC Nut 50107

• 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.
• 5/8" - 11 metal nut allows for quick spin-on, spin-off changeover and eliminates cross-threading or sticking to spindle due to heat build-up.
• Best on steel, stainless steel, aluminum, and other hard-to-grind metals.

Weiler Saber Tooth non-woven Type 29 flap disc uses ceramic as the abrasive material and has a diameter of 4 1/2 in. Since this product is non-woven, grade is generally used to describe the abrasiveness; with the 50107 having a medium grade. Weiler incorporates this ceramic material into the flap disc forming a grit of 80. All abrasive products that rotate or spin, such as the ones in this category, have a maximum speed at which you can run them. This Weiler flap disc can be run at a maximum speed of 13000 RPMs. The Weiler flap disc uses phenolic resin for the backing plate.
