3M 7100077044 Cubitron Ii Roloc Disc 3 Inch 40 Grit

Product Description

The 3M 7100077044 is a 3-inch Cubitron II Roloc abrasive disc designed for aggressive edge grinding and surface preparation in metal fabrication and finishing applications. The disc uses 3M Precision-Shaped Grain technology, which delivers sharp, consistent cutting action while running cool to extend abrasive life. A heavy X-weight poly-cotton backing resists tearing and fraying, making the disc well suited for sustained edge work where standard discs typically break down prematurely. The Roloc quick-change attachment system allows fast tool mounting without additional hardware. Rated to 20000 RPM, this disc handles demanding grinder speeds used in professional metalworking environments.

This disc is intended for metal edge work, weld blending, deburring, and material removal on ferrous and non-ferrous surfaces. The 40-grit designation places it in the coarse range, appropriate for rapid stock removal and shaping rather than finishing passes. Fabricators, welders, and metal tradespeople working with angle grinders or die grinders equipped with Roloc-compatible mandrels will find this disc a practical fit for daily production use.

Installation Notes

Installation and operation of abrasive discs should be performed by qualified tradespeople familiar with grinder safety procedures. Always confirm the tool's rated RPM meets or does not exceed the disc's 20000 RPM maximum before mounting. Inspect the disc for damage before each use and never operate a damaged or frayed disc. Follow ANSI B7.1 and applicable employer safety standards when using abrasive wheels and discs.
