3M 7100006573 Cubitron Ii Roloc Fibre Disc 982C 4 Inch 80 Grit

Product Description

The 3M 7100006573 is the Cubitron II Roloc Fibre Disc 982C, a coated abrasive disc engineered for medium to high pressure grinding on carbon steel. Built on a stiff fiber backing with a strong resin bond, this disc uses 3M Precision Shaped Grain (PSG) technology to deliver fast, consistent stock removal with less operator pressure. At 4 inches in diameter and 80 grit, it is sized for applications where a compact disc is required without sacrificing cut rate or disc life. Licensed tradespeople in fabrication, welding, and metal finishing are the primary installers and operators.

This disc is designed for medium to high pressure grinding applications on carbon steel, including weld grinding, surface preparation, and deburring. The 4-inch diameter and 80-grit cut make it well suited for tight access areas and situations where a smaller disc profile is operationally necessary. The Roloc attachment system allows fast disc swaps between grits or applications without additional tooling, improving workflow efficiency on the job site or in the shop.

Key Features

• Precision Shaped Grain (PSG) maintains sharp cutting points for fast stock removal at reduced pressure
• PSG runs cooler than conventional abrasive grain, minimizing metal discoloration, oxidation, and heat-related stress cracks
• Stiff fiber backing and strong resin bond provide durability and tear resistance for heavy-duty weld grinding
• Roloc attachment system enables quick disc changes between grades or applications
• Extended disc life completes more parts per disc and reduces change-out frequency

Compatibility

Designed for use on carbon steel in medium to high pressure grinding applications. Compatible with Roloc-style angle grinders and die grinders that accept 4-inch quick-change fibre discs.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with abrasive disc safety practices. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Verify that the tool spindle speed rating meets or exceeds the disc maximum RPM before operation. Always use appropriate personal protective equipment including eye protection and gloves when grinding.
