3M 7100076930 Cubitron Ii Roloc Disc 3 Inch 80 Grit

Product Description

The 3M 7100076930 is a 3-inch Cubitron II Roloc abrasive disc designed for edge grinding and surface finishing in metalworking applications. It combines 3M Precision-Shaped Grain technology with a Roloc quick-change attachment system, allowing fast disc swaps without extra tools. The disc is rated to 20000 RPM and backed by a heavy X-weight poly-cotton construction that resists fraying and tearing during aggressive edge work. Evenly spaced grain with built-in gaps helps debris evacuate the cutting surface, reducing loading and extending disc life. Licensed tradespeople working sheet metal, fabrication, and weld prep will find this disc suited to sustained production use.

This disc is used in metalworking environments where consistent edge grinding, weld blending, or surface conditioning is required. The Roloc attachment system is compatible with standard right-angle grinders and die grinders fitted with a Roloc-style mandrel. Applications include automotive body repair, structural steel fabrication, and HVAC sheet metal work. The 80-grit rating makes it appropriate for aggressive material removal while still leaving a workable surface finish. It is suited to both shop and field use in commercial and light industrial settings.

Key Features

• 3M Precision-Shaped Grain delivers sharp, cool, and consistent cutting action throughout disc life

• Heavy X-weight poly-cotton backing withstands edge contact without fraying or tattering
• Roloc quick-change attachment allows fast, secure disc-to-tool mounting without additional hardware
• 20000 RPM rating supports use with standard right-angle and die grinders
• 3-inch diameter and 80 grit suit aggressive edge grinding and weld blending tasks

Compatibility

Designed for use with right-angle grinders and die grinders equipped with a Roloc-compatible mandrel attachment. Verify mandrel thread size and RPM rating match tool specifications before use.

Installation Notes

Installation is performed by pressing the Roloc disc firmly onto a Roloc-style mandrel until it seats and locks. Confirm the tool RPM does not exceed the 20000 RPM disc rating before operation. Wear appropriate PPE including eye protection and gloves when mounting or operating abrasive discs. Inspect the disc for damage before each use and do not use a disc that shows cracking, fraying, or delamination.
