3M 7100045075 Cubitron Ii 6 Inch 120 Grit Abrasive Disc

Product Description

The 3M 7100045075 is a coated abrasive disc built around 3M Precision Shaped Grain technology. The ceramic mineral is formed into a triangular shape that slices through material rather than plowing or gouging like conventional abrasives. The result is a disc rated to cut up to two times faster and last up to four times longer than standard abrasive discs. At 6 inches in diameter and 120 grit, it suits medium-to-fine stock removal passes on metal, composites, and painted surfaces. The PSA (Stik-it) backing allows fast disc changes without tools. Maximum operating speed is 10,000 RPM. This disc is used by fabricators, welders, and metal finishing technicians.

The 7100045075 is designed for aggressive stock removal in grinding and finishing operations. It performs well on ferrous and non-ferrous metals, fiberglass, and hard plastics. The 120 grit level targets applications where significant material removal is needed while leaving a surface finish suitable for the next process step. The PSA attachment system is compatible with hook-and-loop or adhesive-backed backup pads rated for 6-inch discs. Pack quantity is 250 discs per unit of measure, making it a fit for high-volume production or shop environments with regular disc turnover.

Installation Notes

Disc installation and changes should be performed with the tool powered off and unplugged or air supply disconnected. Verify the backup pad is rated for the RPM of the tool before mounting. Do not exceed the 10,000 RPM maximum speed marked on the disc. Inspect each disc for tears or delamination before use and discard damaged discs.
