3M 7010361842 Cubitron Ii Roloc Fibre Disc 982C 4 Inch 80 Grit

Product Description

The 3M 7010361842 is the Cubitron II Roloc Fibre Disc 982C, a coated abrasive disc engineered for medium to high pressure grinding on carbon steel. Built around 3M Precision Shaped Grain (PSG) technology, the disc maintains sharp cutting points that remove material fast while generating less heat than conventional abrasives. At 4 inches in diameter and 80 grit, it is sized for applications where a compact, aggressive disc is required. A stiff fiber backing and strong resin bond provide durability under the sustained load of weld grinding and heavy stock removal. Licensed tradespeople and fabricators in metal fabrication, structural steel, and pipeline work are the primary users of this disc.

This disc is suited for medium to high pressure grinding applications on carbon steel in both shop and field environments. The compact 4-inch format makes it practical for grinding in tight weld joints, corner welds, and areas with limited access. The 80 grit cut rate is appropriate for initial weld blending, surface conditioning, and rapid stock removal before finishing passes. The Roloc twist-on attachment system allows fast disc swaps between grit grades or between applications without additional tooling.

Key Features

• Precision Shaped Grain (PSG) maintains super-sharp cutting points for fast, aggressive material removal
• Cooler running grain reduces metal discoloration, oxidation, and heat-related stress cracking
• Extended disc life completes more parts per disc and reduces change frequency
• Roloc twist-on attachment system enables tool-free disc changes between grades or applications
• Stiff fiber backing and strong resin bond deliver tear-resistance under high-pressure weld grinding loads
• 4-inch diameter suits confined weld areas and applications where a smaller disc is required

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc pads rated for 4-inch coated abrasive fibre discs. Intended for grinding applications on carbon steel.

Installation Notes

Installation is performed by qualified metal fabricators or tradespeople using a Roloc-compatible right-angle grinder fitted with an appropriate disc pad. Confirm the grinder RPM rating meets or exceeds the disc RPM rating before mounting. Inspect the disc for damage before each use and do not use damaged or delaminated discs. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
