4-1/2″ Big Cat Abrasive Flap Disc, Flat (TY27), 40Z, 5/8″-11 UNC

Tiger Big Cat 4.5 inch type 27 high density flap discs offer the widest footprint in the industry for grinding steel and stainless steel. The wider flaps in combination with the thicker high density profile conforms to curved and irregular surfaces better, producing a consistent finish and lasting 30-40% longer than a standard density flap disc. The high density flap 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. A thicker disc with larger flaps which conforms to curved and irregulars surfaces, resulting in a consistent finish. Flap design results in 30-40 percent longer life than standard flap discs. Thicker phenolic back provides more stability for the thicker cloth configuration. Contaminant-free (contains less than 0.1% Fe, S, Cl). Self-sharpening zirconia alumina (ZA) grains hold up under high temperatures and extreme pressure.
