3M 7100126838 Cubitron Ii Roloc Fibre Disc 982C 36 Grit 3 in

Product Description

The 3M 7100126838 is a Cubitron II Roloc Fibre Disc in the 982C series, designed for medium to high pressure grinding on carbon steel. Built around 3M Precision Shaped Grain (PSG) technology, the disc maintains consistently sharp cutting points that remove material faster and with less applied pressure than conventional abrasive grains. At 3 inches in diameter and 36 grit, it is suited for applications where a compact disc size is required without sacrificing aggressive stock removal. The stiff fibre backing and strong resin bond construction make it durable enough for demanding tasks such as weld grinding and deburring.

This disc is intended for use in industrial and fabrication settings where carbon steel grinding, weld blending, and surface preparation are routine operations. The 36 grit designation makes it appropriate for coarse material removal rather than finishing passes. The Roloc twist-lock attachment system allows for fast disc changes between grit grades or different applications, reducing downtime during production work. It is commonly used by metal fabricators, welders, and maintenance technicians working on structural steel, pipe, and heavy plate.

Key Features

• 3M Precision Shaped Grain (PSG) cuts fast with less pressure and maintains sharp points throughout disc life
• Runs cooler than conventional abrasives, reducing metal discoloration, oxidation, and heat-related stress cracks
• Longer disc life means more parts completed per disc and fewer change-outs during production
• Roloc twist-lock attachment system enables quick disc swaps between grades or tasks
• Stiff fibre backing with strong resin bond provides tear resistance for high-pressure weld grinding

Compatibility

Designed for use with Roloc compatible angle grinders and right-angle die grinders that accept 3-inch twist-lock fibre discs. Optimized for grinding on carbon steel in medium to high pressure applications.

Installation Notes

Installation and disc changes should be performed by a qualified operator following the grinder manufacturer's safe operating procedures. Always power down and disconnect the grinder before mounting or removing the disc. Verify that the tool's rated RPM meets or exceeds the disc's maximum rated speed before use. Inspect the disc for damage before each use and discard any disc that shows signs of cracking, delamination, or excessive wear.
