3M 7100076927 Cubitron Ii Roloc Disc 4 Inch 80 Grit

Product Description

The 3M 7100076927 is a 4-inch diameter abrasive disc combining Cubitron II precision-shaped grain technology with a Roloc quick-change attachment system. It is rated for speeds up to 12000 RPM and carries an 80-grit designation for aggressive material removal. The disc is built on a heavy X-weight poly-cotton backing that resists fraying and tearing under sustained edge work. It is designed for use by metalworkers, fabricators, and maintenance technicians who need consistent cut rates and reliable disc life across extended grinding sessions.

This disc is suited for edge grinding, weld blending, and surface stock removal on metal workpieces in both production and maintenance environments. The Roloc attachment system allows fast disc changes without tools, making it practical for high-volume work where downtime between disc swaps matters. The 80-grit construction balances cut rate with surface finish control, positioning it for intermediate material removal stages rather than final finishing.

Key Features

• Cubitron II precision-shaped grain delivers sharp, consistent cutting action while running cooler than conventional abrasive grain
• Evenly spaced grain layout with debris-escape gaps reduces loading and extends disc life
• Heavy X-weight poly-cotton backing resists tearing and fraying during edge work and contour grinding
• Roloc quick-change attachment allows fast, secure disc-to-tool mounting without hand tools
• 80-grit rating supports aggressive stock removal on metal surfaces
• 12000 RPM maximum speed rating compatible with standard right-angle grinders

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc holders that accept 4-inch quick-change abrasive discs.

Installation Notes

Installation is performed by pressing the disc firmly onto a Roloc-compatible mandrel until it seats and locks. Before mounting or removing the disc, confirm the grinder is powered off and disconnected from its power source. Inspect the disc for damage before each use and do not operate above the rated maximum speed of 12000 RPM. Follow ANSI B7.1 and applicable shop safety standards when operating grinding equipment.
