3M 7100045074 Cubitron Ii 6 Inch 120 Grit Abrasive Disc

Product Description

The 3M 7100045074 is a coated abrasive disc from the Cubitron II line, featuring 3M Precision Shaped Grain technology. The triangular ceramic mineral is engineered to slice through material rather than gouge or plow, delivering faster stock removal compared to conventional abrasive discs. At 6 inches in diameter and 120 grit, this disc runs at up to 12000 RPM and attaches via the Stikita pressure-sensitive adhesive backing for quick pad changes. It is suited for metalworking, fabrication, and surface preparation tasks where consistent cut rate and disc longevity matter.

This disc is designed for stock removal applications across a wide variety of substrates including steel, stainless steel, aluminum, and other metals. The Stikita backing system allows the disc to mount directly to compatible Stikita backup pads without additional hardware. It is commonly used in production grinding, weld blending, and general surface conditioning in shop and field environments. Licensed trades and fabrication professionals working on metal components will find it suited to both handheld random orbital and fixed-speed grinder setups.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or the air supply disconnected.

Wear appropriate eye and hearing protection during operation, per standard shop safety requirements.
