3M 7000044903 Cubitron Ii Roloc Fibre Disc 982C 60 Grit 2 in

Product Description

The 3M 7000044903 is a Cubitron II Roloc Fibre Disc in the 982C series, engineered for medium to high pressure grinding on carbon steel. At 2 inches in diameter with a 60 grit rating, this coated abrasive disc uses 3M Precision Shaped Grain (PSG) technology to maintain super-sharp cutting points that remove material fast and with less applied pressure. The stiff fiber backing and strong resin bond make it well suited for demanding tasks such as weld grinding where durability and tear resistance are required. Licensed tradespeople in fabrication, welding, and metalworking shops are the primary installers and end users of this disc.

This disc is sized for applications where a smaller format abrasive is needed without sacrificing cutting performance. It targets carbon steel stock removal in production environments where disc life and part throughput matter. The Roloc attachment system allows fast disc swaps between grit grades or task changes, supporting efficient workflow on the shop floor or in the field. Its cooler-running PSG grain helps reduce metal discoloration and oxidation, which is critical when heat-affected zones and stress cracks must be avoided near welds or finished surfaces.

Key Features

• Precision Shaped Grain (PSG) cuts fast with less pressure and maintains sharp points longer than conventional abrasive grain
• Cooler cutting action reduces metal discoloration, oxidation, and the risk of heat-related stress cracks
• Significantly longer disc life compared to standard fibre discs, reducing changeover frequency and cost per part
• Roloc attachment system enables tool-free disc changes between grades or applications
• Stiff fiber backing with strong resin bond delivers durability and tear resistance under high-pressure weld grinding loads
• Compact 2 inch diameter fits tight access areas where larger discs cannot be used

Compatibility

Designed for use on carbon steel in medium to high pressure grinding applications. Compatible with Roloc-style right angle grinders and die grinders that accept 2 inch quick-change fibre discs.

Installation Notes

Install only on a grinder rated for the disc diameter and speed. Ensure the Roloc mandrel is properly seated and locked before operation. Always wear appropriate eye protection, a face shield, and gloves when operating grinding discs. Inspect the disc for damage or delamination before each use and discard any disc that shows signs of wear beyond the usable abrasive layer.
