Norton4 1/2" X 1/4" X 5/8" - 11 Quantum3 20 Grit Ceramic Type 27 Depressed Center Grinding Wheel
Norton Quantum3 grinds faster, with less pressure, to significantly increase production while using fewer wheels. The best industry metal removal rate is gained from the larger grit size of a proprietary Saint-Gobain grain. Bond is matched to grain to produce the highest level of performance: metal removal rate and wheel life.
