4-1/2 Tiger Ceramic High Density (TY27) Abrasive Flap Disc, 40C, 5/8"-11 UNC Nut

Tiger Ceramic 4.5 inch high density 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 27 flat style high density design is conformable to irregular surfaces when grinding between 0° – 15° 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.

Features and Benefits

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).
High density flap design is conformable to irregular 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.
