Metal grinding performance graph for 3M™ Cubitron™ II Disc and two competitors

Faster cut. Longer life. More durable.

Boost productivity in grinding and refining.

When you’re using a disc sander, you’re relying on the edge of the abrasive disc to grind and refine. 3M™ Cubitron™ II Roloc™ Durable Edge Disc 984F delivers faster performance with fewer edge failures on most metals, including mild steel and stainless steel. The durable edge backing improves edge retention, preventing fraying and early wear-out. Meanwhile, 3M Precision-Shaped Ceramic Grain self-sharpens for fast, consistent and continuous cutting with less pressure.

Check out the testing data on the right to see how 3M™ Cubitron™ II Durable Edge Disc 984F outperforms the competition.

Product Details

3M Precision-Shaped Grain (PSG) maintains super-sharp points that cut exceptionally fast with less pressure
Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes
Grinding aid incorporated on the disc minimizes grinding temperatures for stainless steel and other heat-sensitive alloys
Roloc™ quick attachment system provides for easy disc changes between grades or applications
Backing supports medium to high pressure grinding applications and 2-ply construction provides added durability for edge work

3M™ Cubitron™ II Roloc™ Durable Edge Disc 984F offers a superior solution for tackling medium to high pressure grinding applications when a smaller-sized disc is needed. It excels in stainless steel, cobalt chrome, and nickel alloy applications.

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.
