The 3M Cubitron 3 Roloc Fibre Disc 1187C features re-engineered 3M Precision-Shaped Grain — taking the legendary speed and life of 3M Cubitron Performance Abrasives to a whole new level. These product benefits include allowing for increased productivity and lower overall grinding costs vs. other competitive quick-change discs when grinding a variety of metals, including stainless steel and other heat-sensitive alloys. This long-lasting disc has a fast cut rate with high stock removal across a wide range of application pressures; it also features a grinding aid that minimizes temperatures for heat-sensitive alloys. Additionally, this disc is designed to increase throughput and complete more parts-per-disc when tackling medium to high-pressure grinding applications.The 3M Cubitron 3 Roloc Fibre Disc 1187C is engineered to help operators take on a variety of tasks with less fatigue. This is made possible through this disc's exceptionally high cut rate that requires less pressure than conventional abrasives, combined with the added benefit of an incorporated grinding aid to help keep the disc cooler on heat-sensitive metals, reducing metal discoloration/oxidation and the chance of heat-related stress cracks. This disc's stiff fiber backing and strong resin bond provide durability and tear resistance to help ensure operators can work on medium to high-pressure grinding projects — jobs made even easier thanks to re-engineered 3M Precision-Shaped Grain, which slices cleanly through metal, wears evenly, and continuously self-sharpens as the points break off.
