3M 7100076895 Cubitron Ii Roloc Disc 4 Inch 120 Grit

Product Description

The 3M 7100076895 is a Cubitron II Roloc durable edge abrasive disc designed for fast, consistent material removal on corners, edges, and contoured surfaces. Built on a heavy X-weight poly-cotton backing, this 4-inch, 120-grit disc resists fraying and tattering even under sustained edge pressure. The Roloc threaded attachment system allows quick disc changes without tools. Rated to 12,000 RPM, it suits high-speed angle grinders and die grinders used in metal fabrication, weld blending, and surface prep applications. Licensed metalworking professionals and fabricators are the primary installers and users of this disc.

This disc is suited for metal grinding, weld seam blending, deburring, and edge finishing on steel, stainless steel, and other ferrous metals. The 120-grit rating positions it for intermediate finishing work where a smooth surface profile is required after heavier stock removal. The Roloc attachment is compatible with standard Roloc-style backer pads used on right-angle grinders and die grinders common in fabrication and maintenance shops.

Installation Notes

Installation is performed by metalworkers, fabricators, and maintenance technicians. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Thread the Roloc disc onto a compatible backer pad until it seats firmly, and confirm the tool RPM rating does not exceed the disc maximum of 12,000 RPM. Always wear appropriate PPE including eye and face protection when operating rotary abrasives.
