• Active grinding agent provides cool cutting with light pressure
• Trimmable Z3 flap disc backing easily trims down to expose flaps for extended working life
• The trimmable backing allows for longer production times since wheels aren't changed as often
• Premium Zirconia Alumina grain with a poly/cotton heat treated backing
• To trim down the backing simply grind the backing edge against a metal edge until the flaps are exposed to the level needed. Flaps are compressed at a 4 degree angle for flap edge strength. Best used at 5°–20° angle.
• Recommended for aggressive use and heavy duty applications
