3M 7100006574 Cubitron Ii Roloc Fibre Disc 982C 60 Grit 4 in

Product Description

The 3M 7100006574 is a Cubitron II Roloc Fibre Disc in the 982C series, designed for medium to high-pressure grinding on carbon steel. It measures 4 inches in diameter and carries a 60-grit rating. The disc uses 3M Precision Shaped Grain (PSG) technology, which maintains sharp cutting points that remove material fast while generating less heat than conventional abrasive grain. The stiff fiber backing and strong resin bond make it well suited for demanding applications such as weld grinding and deburring. Installers and fabricators handling smaller workpieces will find this disc practical where a full-size wheel is impractical.

This disc is intended for use in metal fabrication, structural steel work, and maintenance grinding applications where a compact 4-inch disc is required. It is particularly effective on carbon steel surfaces that are sensitive to heat-related discoloration or oxidation. The Roloc quick-change attachment system allows fast swaps between grit grades or disc types without additional tooling, making it efficient for production environments where multiple finishing steps are performed in sequence.

Key Features

• 3M Precision Shaped Grain (PSG) delivers fast cutting with reduced pressure requirements
• Cooler running grain minimizes metal discoloration, oxidation, and heat-related stress cracks
• Extended disc life completes more parts per disc and reduces change-out frequency
• Roloc quick-change attachment system enables fast disc swaps between grades or applications
• Stiff fiber backing with strong resin bond provides durability and tear resistance for high-pressure weld grinding

Compatibility

Designed for use with Roloc-compatible angle grinders and die grinders that accept 4-inch quick-change fibre discs. Intended for grinding applications on carbon steel.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Ensure the grinder is powered off and disconnected from its power source before mounting or removing the disc. Confirm the tool spindle speed does not exceed the maximum RPM rating marked on the disc. Inspect the disc for damage before each use and discard any disc that shows cracks, tears, or unusual wear.
