3M 7100313187 Cubitrona 3 Cut-off Wheel 4.5 in 36 Grit

Product Description

The 3M 7100313187 Cubitrona 3 Cut-Off Wheel is a 4.5-inch abrasive cut-off wheel engineered for high-speed material removal on metal fabrication and maintenance tasks. It uses 3M Re-Engineered Precision Shaped Ceramic Grain, a proprietary molecular bonding technology that forms sharp, angular structures. These structures continuously fracture to expose fresh cutting edges, allowing the wheel to run cool and wear evenly. At 0.125 inches thick with a 36-plus grit rating, it is built for trades that demand fast, clean cuts and extended wheel life on demanding materials.

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 appropriate for tight clearance work and repetitive cuts in metal fabrication shops, automotive service, marine maintenance, and industrial maintenance applications. Licensed tradespeople and experienced fabricators working with angle grinders will find it applicable across a wide range of ferrous and specialty metal cutting tasks.

Key Features

• Re-Engineered Precision Shaped Ceramic Grain continuously fractures to maintain sharp cutting edges and run cool throughout use
• Up to 10 percent increased cut rate compared to Cubitrona II Performance Abrasives, reducing time and pressure required per cut
• Removes up to 3 times more material compared to Cubitrona II Performance Abrasives, reducing changeover frequency
• 4.5-inch diameter with 0.125-inch thickness supports perpendicular cuts through a wide range of metal profiles
• Compatible with almost all metals including stainless steel, mild steel, and aerospace alloys

Compatibility

Designed as a replacement and upgrade over Cubitrona II Performance Abrasives for use on angle grinders accepting 4.5-inch cut-off wheels. Suitable for cutting stainless steel, mild steel, aerospace alloys, autobody and marine sheet metal, exhaust components, clamps, and rusted fasteners.

Installation Notes

Installation and mounting of cut-off wheels should be performed by qualified personnel following the grinder manufacturer's instructions and applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the grinder from its power source before changing wheels. Inspect the wheel for cracks or damage before mounting and confirm the grinder's rated RPM meets or exceeds the wheel's maximum operating speed. Never use a cut-off wheel for side grinding.
