3M 7100312963 Cubitrona 3 Ceramic Cut-off Wheel 7 in

Product Description

The 3M 7100312963 Cubitrona 3 Cut-Off Wheel is a high-performance abrasive wheel engineered with 3M Precision Shaped Ceramic Grain. At 7 inches in diameter and 0.09 inches thick, with a 36-plus grit rating, it is built for fast, consistent cutting across a wide range of materials. The proprietary ceramic grain continuously fractures to expose sharp cutting points, which allows the wheel to run cooler and wear more evenly over its service life. Fabricators, welders, and metalworkers reach for this wheel when cut rate and wheel longevity both matter on the same job.

This cut-off wheel is suited for demanding metal fabrication tasks in industrial, automotive, marine, and aerospace environments. Typical applications include cutting stainless steel tubing, mild steel plate, exhaust pipes, clamps, rusted fasteners, and autobody or marine sheet metal. It is designed for use with angle grinders and cut-off tools that accept 7-inch wheels. The perpendicular cutting action, applied through the outer edge of the wheel, produces clean through-cuts with minimal secondary finishing required.

Key Features

• Precision Shaped Ceramic Grain fractures continuously to maintain sharp cutting points and extend wheel life
• Delivers up to 10 percent increased cut rate compared to the Cubitrona II Performance Abrasives line
• Removes up to 3 times more material per wheel compared to Cubitrona II Performance Abrasives
• 7-inch diameter and 0.09-inch thickness optimized for perpendicular cuts on tubing, pipe, and sheet stock
• Compatible with stainless steel, mild steel, and aerospace alloys
• Runs cooler than conventional abrasive grain, reducing workpiece heat distortion risk

Compatibility

Designed as a direct-fit cut-off wheel for angle grinders and cut-off machines that accept 7-inch abrasive wheels. Suitable for use on stainless steel, mild steel, and aerospace alloys.

Installation Notes

Mount and operate this wheel only on tools rated for 7-inch cut-off wheels and only at or below the maximum RPM marked on the wheel. Power down and disconnect or lock out the tool before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and discard any damaged wheel immediately. Always wear appropriate eye protection and a face shield when operating abrasive cut-off wheels, and ensure the work area is clear of flammable materials when cutting metals that produce sparks.
