To save time and increase throughput, our 3M Cubitron II Roloc Durable Edge Disc 984F combines the convenience of the 3M Roloc Quick-Change Attachment System with 3M proprietary Precision-Shaped Grain (PSG) technology, delivering outstanding cut rates and disc life. For long life and durability, we used a laminated 2-ply polyester backing for wear-resistance in edge work.
Because PSG contributes to an exceptionally high cut-rate with less pressure, operators can finish tough tasks faster and with less fatigue. A grinding aid incorporated on the disc makes this an outstanding product for all types of metal, it helps keep the disc cooler on stainless steel and heat-sensitive metals such as nickel alloys and titanium, thereby reducing metal discoloration/oxidation and the chance of heat-related stress cracks.
Our 3M Cubitron II products have raised the bar for high-performing abrasives. 3M Precision-Shaped Grain outcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance. The result is that operators can grind faster and complete more parts per disc with less muscle-work and fatigue.
To create PSG, our team of engineers started with 3M Ceramic Abrasive Grain and used proprietary technology to form the grains into triangular structures and electrostatically orient them on the backing to form sharp peaks that maximize cutting potential. These peaks slice cleanly through metal, rather than gouging or plowing as traditional abrasives do, and continuously self-sharpen as the points break off. This generates a super-fast cut and lessens heat build-up due to friction, reducing heat-related stress cracks and discoloration.
PSG also wears evenly, and because the abrasive itself stays cooler and sharper, Cubitron II products last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications.
3M Cubitron II Roloc Durable Edge Disc 984F is available for use with the following Roloc attachment systems: TR, TSM and TS. Please select discs with the attachment design made for your system.
