3M 7100076928 Cubitron Ii Roloc Abrasive Disc 80 Grit

Product Description

The 3M 7100076928 is a Cubitron II Roloc durable edge abrasive disc rated at 80 grit and designed for high-speed grinding and finishing work on metal surfaces. It runs at up to 30000 rpm and measures 1.5 inches in diameter. The disc uses 3M Precision-Shaped Grain technology to deliver sharp, cool, and consistent cutting action throughout its service life. A poly-cotton X-weight backing resists tearing and fraying, making it reliable for edge work where standard discs tend to break down. The Roloc quick-change attachment system allows fast, tool-free disc swaps during production grinding operations.

This disc is suited for metal fabrication, weld blending, deburring, and edge finishing in industrial and shop environments. The 1.5-inch diameter makes it well suited for tight areas, contours, and edge profiles where larger discs cannot reach. It is typically installed and used by metalworkers, welders, fabricators, and maintenance technicians working with die grinders and other Roloc-compatible pneumatic or electric rotary tools. The evenly spaced grain pattern helps debris escape during cutting, reducing disc loading and extending usable life on ferrous and non-ferrous workpieces.

Key Features

• 3M Precision-Shaped Grain for sharp, cool, and consistent cutting throughout disc life
• Evenly spaced grain with debris-escape gaps resists loading during use
• Poly-cotton X-weight backing provides high tensile strength and edge durability
• Heavy backing resists tearing and fraying on sharp workpiece edges
• Roloc quick-change attachment allows fast disc-to-tool connection without additional hardware

Compatibility

Designed for use with Roloc-compatible die grinders and rotary tools that accept 1.5-inch quick-change abrasive discs.

Installation Notes

Installation is performed by pressing the Roloc disc onto a compatible Roloc mandrel until it seats and locks. Confirm the tool is rated for at least 30000 rpm before mounting. Power down and disconnect the tool from its air or electrical supply before changing discs. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or unusual wear.
