3M Cubitron II Fibre Disc 987C, TN Quick Change, 7 in, 60+, 25/Bag

This mineral is an exceptionally high-performing ceramic, resin-bonded to a stiff fiber backing. To create 3M Precision-Shaped Grain, engineers start with 3M™ Ceramic Abrasive Grain and use proprietary technology to form the grains into triangular structures and electrostatically orient them on the backing to form sharp peaks that maximize cutting potential.

3M PSA Cloth Disc 777F, 50 YF-weight, 12 in x NH, Die 1200B

To protect heat sensitive alloys like stainless steel, nickel alloys and cobalt alloys, a grinding aid on the 777F cloth disc reduces running temperatures, and the abrasive is bonded to the backing with resin to maintain disc durability under high heat and pressure.
