Tiger Original 6 inch conical flap discs are designed for aggressive grinding and long life when grinding steel and stainless steel. The type 29 conical disc shape maximizes surface contact when grinding between 15° & 35° for aggressive stock removal on flat surfaces while the 80 grit abrasive grain is ideal for blending, rust removal, cleaning, and finishing 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.
