3M 7100076899 Cubitron Ii Roloc Disc 4 Inch 60 Grit

Product Description

The 3M 7100076899 is a 4-inch Cubitron II Roloc durable edge abrasive disc designed for aggressive material removal with long-lasting performance. It combines 3M Precision-Shaped Grain technology with a poly-cotton heavy X-weight backing and a Roloc quick-change attachment system. The disc runs at up to 12000 RPM and is rated for edge grinding applications where disc integrity under lateral stress is critical. Licensed HVAC sheet metal technicians, metal fabricators, and pipefitters use this disc for deburring, edge blending, and weld preparation on ferrous and non-ferrous substrates.

This disc is suited for edge work on flat stock, pipe, structural steel, and weld seams in both shop and field environments. The 60-grit classification makes it a general-purpose cut for stock removal without excessive surface finish requirements. Its evenly spaced grain pattern resists loading during extended use, which reduces downtime from disc changes. The Roloc attachment system allows fast disc swaps on compatible angle grinders and die grinders without additional hardware.

Key Features

• 3M Precision-Shaped Grain delivers sharp, consistent cutting action with lower heat buildup
• Evenly spaced grain with open gaps reduces loading and extends disc life
• Heavy X-weight poly-cotton backing resists tearing and fraying during edge contact
• Roloc quick-change attachment allows tool-free disc swaps on compatible grinders
• Rated to 12000 RPM for use on standard angle and die grinders
• 4-inch diameter at 60 grit suited for aggressive stock removal and weld blending

Compatibility

Designed for use with Roloc-compatible angle grinders and die grinders accepting 4-inch quick-change abrasive discs.

Installation Notes

Installation is performed by aligning the Roloc stem with the tool spindle and pressing until the attachment locks. Always verify the tool spindle speed does not exceed the disc maximum rating of 12000 RPM before operation. Wear appropriate eye and face protection per ANSI Z87.1 standards during grinding operations. Inspect the disc for damage before each use and discard any disc showing fraying, tears, or separation of the backing.
