• Trimmable Zirconia flap disc backing easily trims down to expose flaps for extended working life and allows more of the flap disc to be used for fewer disc change • Premium Zirconia Alumina grain with a poly/cotton heat treated backing provides low stretch and strengh for the high Zirconia concentration. • Recommended for aggressive use and heavy duty applications • To trim down the backing simply grind the backing edge against a metal edge until the flaps are exposed to the level needed • Contaminate-free.
TYPE 27 ALUMINUM FLAP DISCS
• Unique design for aluminum applications • Aluminum Oxide with special treatment of calcium stearate to keep material cooler and prevent loading with soft materials
