3M 7100044455 Cubitron Ii 6 Inch 80 Grit Abrasive Disc

Product Description

The 3M 7100044455 is a Cubitron II coated abrasive disc engineered for high-speed stock removal on metal, wood, and composite substrates. It uses 3M Precision Shaped Grain technology, a ceramic mineral formed into a triangular shape that slices through material rather than plowing like conventional abrasives. The result is a disc rated to cut up to twice as fast and last up to four times longer than standard abrasive discs. At 6 inches in diameter and 80 grit, it is sized for angle grinders and random orbital tools running up to 10000 RPM. The Stikfit pressure-sensitive adhesive backing allows fast disc changes without tools.

This disc is suited for fabrication shops, metalworking operations, and surface prep applications where aggressive material removal is the priority. Common use cases include weld blending, deburring, and rough stock removal on steel and stainless steel. The 80-grit designation places it in the coarse range, making it appropriate for initial shaping passes rather than finish work. It is sold per each and is a standard choice for professional metal fabricators and industrial maintenance technicians.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive tool safety. Confirm the tool spindle speed does not exceed the 10000 RPM rating of the disc before mounting. Ensure the tool is powered off and unplugged before removing or attaching discs. Always use appropriate eye protection, hearing protection, and respiratory PPE when operating coated abrasive discs.
