3M 7100076923 Cubitron Ii Roloc 947A Disc 4 Inch 60 Grit

Product Description

The 3M 7100076923 is a Cubitron II Roloc 947A Durable Edge Disc engineered for aggressive, consistent material removal on metal and fabricated surfaces. It combines 3M Precision-Shaped Grain technology with a poly-cotton X-weight backing and a Roloc quick-change attachment system. The disc runs at up to 12000 RPM and measures 4 inches in diameter with a 60-grit cut, making it well-suited for edge grinding, weld blending, and surface preparation where abrasive durability and cut consistency are critical. Licensed fabricators and metal finishing technicians rely on this disc for production-level throughput.

This disc is designed for edge work and general grinding on ferrous and non-ferrous metals in fabrication shops, maintenance environments, and light manufacturing. The Roloc attachment system allows fast disc changes on compatible Roloc-style angle grinders and disc pads, reducing downtime between passes. The 60-grit grade positions it for stock removal and coarse surface conditioning rather than finishing passes.

Key Features

• 3M Precision-Shaped Grain provides sharp, cool, and consistent cutting action throughout disc life
• Evenly spaced grain layout creates debris escape paths that reduce loading and extend abrasive life
• Poly-cotton X-weight backing delivers high tensile strength for edge work without tattering or fraying
• Roloc quick-change attachment enables fast, secure disc-to-tool mounting without tools
• Rated to 12000 RPM for use on standard pneumatic and electric angle grinders

Compatibility

Designed for use with Roloc-style disc pads and compatible right-angle grinders or die grinders that accept the Roloc attachment system.

Installation Notes

Installation and disc changes must be performed with the grinder powered off and disconnected from the air supply or electrical source. Inspect the disc for damage before each use and do not exceed the 12000 RPM maximum rated speed. Eye protection, gloves, and appropriate guarding are required per ANSI B11 and applicable shop safety standards. Do not apply excessive lateral pressure to the disc during edge grinding operations.
