3M 7100076922 Cubitron Ii Roloc Disc 3 Inch 60 Grit

Product Description

The 3M 7100076922 is a 3-inch Cubitron II Roloc abrasive disc designed for edge grinding and finishing applications in metal fabrication and welding environments. It runs at up to 20000 RPM and cuts at 60 grit, making it suitable for aggressive stock removal on edges and contoured surfaces. The disc uses 3M Precision-Shaped Grain technology, which delivers sharp, consistent cutting with lower heat buildup compared to conventional abrasive grain. A poly-cotton X-weight backing resists tearing and fraying, which is especially important when working against hard edges. The Roloc threaded hub attachment allows fast disc changes without tools.

This disc is built for edge work on metal surfaces where durability under lateral stress matters. Typical applications include weld blending, edge chamfering, and surface conditioning on structural steel, sheet metal, and fabricated parts. It is commonly used by metal fabricators, welders, and maintenance technicians using 3-inch right-angle grinders or die grinders fitted with a Roloc mandrel. The 60-grit cut rate suits initial material removal before transitioning to finer finishing steps.

Key Features

• 3M Precision-Shaped Grain provides sharp, cool, consistent cutting action across the disc life
• Evenly spaced grain layout creates gaps that allow debris to escape and resist loading
• Heavy X-weight poly-cotton backing resists tearing and fraying during edge work
• Roloc threaded attachment allows tool-free disc changes in seconds
• 3-inch diameter at 60 grit rated to 20000 RPM

Compatibility

Designed for use with 3-inch Roloc-compatible right-angle grinders and die grinders fitted with a Roloc mandrel attachment.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from the power source. Thread the Roloc hub onto a compatible Roloc mandrel until fully seated before operating. Do not exceed the rated 20000 RPM maximum speed. Disc inspection before each use is recommended per ANSI B7.1 guidelines; discard any disc showing tears, fraying, or hub damage.
