3M 7100304010 Cubitrona 3 Cut-off Wheel 5 in 36+ Grit

Product Description

The 3M 7100304010 Cubitrona 3 Cut-Off Wheel is a 5-inch diameter, 0.045-inch-thick abrasive wheel engineered for high-speed material removal across a wide range of metals. It uses 3M Re-Engineered Precision Shaped Ceramic Grain, a proprietary molecular bonding technology that creates sharp, angular structures. These structures continuously fracture to expose fresh cutting edges, allowing the wheel to run cooler, wear more evenly, and maintain cutting efficiency throughout its service life. This wheel is rated at 36+ grit and is designed for demanding metal fabrication and maintenance tasks performed by trade professionals.

This cut-off wheel is suited for use on stainless steel, mild steel, aerospace alloys, autobody sheet metal, marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners. It performs perpendicular cuts using the outer edge of the wheel, making it well matched to grinder-based cutting operations in fabrication shops, automotive service bays, marine yards, and industrial maintenance environments. The 0.045-inch profile keeps cuts narrow and minimizes material loss.

Key Features

• 5-inch diameter, 0.045-inch-thick wheel rated at 36+ grit for fast, controlled cutting
• Re-Engineered Precision Shaped Ceramic Grain continuously fractures to maintain sharp cutting edges and reduce heat buildup
• Delivers up to 10% faster cut rate compared to Cubitrona II Performance Abrasives
• Removes up to 3 times more material per wheel compared to Cubitrona II Performance Abrasives, reducing changeover frequency
• Designed for perpendicular cuts on metal including tubing, sheet metal, fasteners, and exhaust components
• Compatible with stainless steel, mild steel, and aerospace alloys

Compatibility

Designed for use on stainless steel, mild steel, aerospace alloys, autobody and marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners. Intended for use with standard 5-inch angle grinders accepting cut-off wheels of this profile.

Installation Notes

Cut-off wheels must be installed and operated by personnel familiar with angle grinder safety practices. Always inspect the wheel for cracks or damage before mounting and confirm the grinder RPM rating meets or exceeds the wheel rating. Power down and disconnect the grinder from its power source before changing wheels. Follow ANSI B7.1 guidelines for the safe use, handling, and protection of abrasive wheels.
