3M 7000118431 Cubitron Ii Roloc Fibre Disc 982C 60 Grit 2 in

Product Description

The 3M 7000118431 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 and 60 grit, this disc is sized for tight-access work where a standard larger disc will not fit. It uses 3M Precision Shaped Grain (PSG) technology, which maintains sharp cutting points throughout the disc life, removing material faster and with less applied pressure than conventional abrasive grains. A stiff fiber backing and strong resin bond give the disc the structural integrity required for demanding tasks such as weld grinding and edge work on carbon steel fabrications. Licensed trades and fabrication shops install this disc in right-angle grinders equipped with a Roloc-compatible mandrel.

This disc is suited for residential and commercial metal fabrication, structural steel work, weld blending, and surface preparation on carbon steel. The 2-inch diameter makes it practical for confined weld joints, pipe saddles, tight corners, and other areas where larger discs cannot reach effectively. The Roloc attachment system allows fast disc swaps between grits or disc types without tools, reducing downtime during multi-step grinding and finishing operations. It is appropriate for use by welders, pipefitters, ironworkers, and metal fabricators who require consistent stock removal in restricted work envelopes.

Key Features

• 3M Precision Shaped Grain maintains sharp cutting points for fast stock removal with reduced applied pressure
• Runs cooler than conventional abrasives, minimizing metal discoloration, oxidation, and heat-related stress cracks
• Stiff fiber backing and strong resin bond provide tear-resistance for high-pressure weld grinding
• Roloc attachment system allows tool-free disc changes between grades and applications
• Extended disc life means more parts completed per disc and fewer change-outs during production runs
• 2-inch diameter targets confined areas and tight-access weld joints inaccessible to larger discs

Compatibility

Designed for use with right-angle grinders fitted with a Roloc-compatible mandrel. Intended for medium to high pressure grinding applications on carbon steel surfaces.

Installation Notes

Mounting is performed by pressing the Roloc disc firmly onto a compatible threaded mandrel until it locks in place. Verify the grinder RPM rating meets or exceeds the disc RPM rating before operation. Always install and remove abrasive discs with the grinder powered off and disconnected from its power source. Wear appropriate PPE including eye protection and a face shield when operating grinding discs.
