Time is Money. Trimming the backing allows for more of the disc to be used for fewer disc changes and better production rates. Easy Trimming, simply angle the backing edge against a hard metal to expose more flap material. Stiff backing construction paired with a compacted 4 degree flap angle makes grinding easier, quieter and with less vibration. Z3 (Zirconia) for fast, long-lasting grinding.
