Tiger Paw, 4-1/2 in high density flap discs are designed for demanding metalworking applications like edge grinding on steel and stainless steel. Tiger Paw, leverages 100% zirconia alumina grain that holds up under high temperatures and extreme pressure delivering high performance on heavy duty applications. The high density flap design is conformable to irregular surfaces. The type 29 conical disc shape maximizes surface contact when grinding between 15 to 35 deg for aggressive stock removal on flat surfaces while the 80 grit abrasive grain is ideal for edge beveling, chamfering, weld grinding, blending, deburring, deflashing, and rust removal with a right angle grinder.
