3M 7100077041 Cubitron Ii Roloc Disc 4 Inch 40 Grit

Product Description

The 3M 7100077041 is a Cubitron II Roloc durable edge abrasive disc designed for aggressive, consistent material removal on metal and other hard surfaces. Built on a heavy X-weight poly-cotton backing, this 4-inch disc runs at up to 12000 RPM and uses 3M Precision-Shaped Grain technology to deliver sharp, cool cutting action throughout the life of the disc. The Roloc quick-change attachment system allows fast, tool-free disc swaps. Licensed tradespeople and fabricators working on grinding, blending, and edge-finishing applications will find this disc well suited to sustained production use.

This disc is intended for edge work, deburring, weld blending, and surface conditioning on metal fabrication and structural steel applications. The 40-grit designation makes it appropriate for aggressive stock removal rather than fine finishing. The Roloc attachment is compatible with standard Roloc-style backing pads found on right-angle grinders and die grinders used in industrial, HVAC fabrication, and general metalworking settings.

Key Features

• 3M Precision-Shaped Grain provides sharp, cool, consistent cutting action with reduced heat buildup
• Evenly spaced grain layout allows debris to escape, resisting disc loading and extending abrasive life
• Heavy X-weight poly-cotton backing resists tearing and fraying during edge work
• Roloc quick-change attachment allows fast disc-to-tool mounting without tools
• 4-inch diameter at 40 grit rated to 12000 RPM for use on right-angle and die grinders

Compatibility

Designed for use with standard Roloc-style quick-change backing pads on right-angle grinders and die grinders. No specific model compatibility was provided in the product data.

Installation Notes

Installation and disc changes should be performed by qualified personnel following all applicable ANSI abrasive safety standards. Verify that the grinder's rated RPM meets or exceeds 12000 RPM before mounting this disc. Power down and disconnect the grinder from its power source before attaching or removing the disc. Always inspect the disc for damage before use and wear appropriate PPE including face shield and gloves.
