3M 7100303860 Cubitrona 3 Cut-off Wheel 3 in 60+ Grit

Product Description

The 3M 7100303860 is a Cubitrona 3 cut-off wheel engineered for fast, precise cuts through a wide range of metals. It measures 3 inches in diameter with a 0.035-inch thickness and carries a 60-plus grit rating. The wheel 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 cooler, wear more evenly, and maintain cut rate throughout its service life. It is suited for use by metalworkers, fabricators, auto body technicians, and marine service professionals.

This cut-off wheel is designed for perpendicular cutting using the outer edge of the wheel. Typical applications include autobody and marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners. It performs across a broad material range, including stainless steel, mild steel, and aerospace alloys. According to 3M, this wheel delivers up to 10 percent greater cut rate and removes up to three times more material compared to the Cubitrona II Performance Abrasive wheels, reducing changeover frequency on demanding jobs.

Key Features

• 3M Re-Engineered Precision Shaped Ceramic Grain continuously fractures to maintain sharp cutting edges and even wear
• 3-inch diameter, 0.035-inch thickness optimized for perpendicular cut-off work
• Up to 10 percent increased cut rate vs. Cubitrona II Performance Abrasives, reducing time and operator pressure
• Removes up to 3x more material per wheel vs. Cubitrona II, lowering changeover frequency
• Compatible with stainless steel, mild steel, aerospace alloys, exhaust components, and sheet metal
• Runs cooler than conventional abrasive wheels, reducing heat buildup at the cut zone

Compatibility

Designed for use on angle grinders and cut-off tools accepting 3-inch diameter wheels. Suitable for cutting stainless steel, mild steel, aerospace alloys, autobody sheet metal, marine sheet metal, exhaust pipes, clamps, and rusted fasteners.

Installation Notes

Installation and wheel changes should be performed by qualified personnel following the grinder or cut-off tool manufacturer's instructions and all applicable ANSI B7.1 safety standards. Always power down and disconnect the tool before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never exceed the maximum RPM rating marked on the wheel. Eye protection, gloves, and appropriate respiratory PPE are required during operation.
