3M Precision-Shaped Grain maintains sharp points that helps cut exceptionally fast with less pressureDisc life is significantly longer, completing more parts per disc and requiring fewer disc changesHelps reduce change-outs and downtime in robotic and pressure-assisted applicationsTriangular shaped ceramic grain lasts up to two times longer than other ceramic abrasives, wears evenly, runs cool, and optimizes mineral breakdownStiff fibre backing and a strong resin bond help provide durability and resistance to tear for heavyweight applications such as high-pressure weld grinding and bevelingContaminant-free under INOX standard for stainless steel
