3M 7100303858 Cubitrona 3 Ceramic Cut-off Wheel 3 in

Product Description

The 3M 7100303858 is a 3-inch ceramic abrasive cut-off wheel engineered for high-speed metal cutting in demanding trade applications. Built with 3M Precision Shaped Ceramic Grain, the wheel delivers a fast cut rate and extended service life compared to conventional abrasive wheels. At 0.045 inches thick and rated at 60 plus grit, it is designed for perpendicular cutting using the outer edge of the wheel. Licensed tradespeople working on fabrication, maintenance, and repair tasks will find this wheel suited for continuous production cutting where changeover time and wheel consumption directly affect job cost.

This cut-off wheel is designed 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 is appropriate for both shop and field use where a thin-kerf, fast-cutting wheel is required. The 3-inch diameter suits right-angle die grinders and cut-off tools commonly used by HVAC technicians, pipefitters, welders, auto body technicians, and general maintenance tradespeople.

Key Features

• Precision Shaped Ceramic Grain fractures continuously to expose sharp cutting points, reducing heat buildup and extending wheel life
• Delivers up to 10% faster cut rate compared to Cubitrona II Performance Abrasives, reducing operator pressure and cycle time
• Removes up to 3 times more material per wheel compared to Cubitrona II Performance Abrasives, reducing changeover frequency
• 0.045-inch thickness produces a narrow kerf for clean perpendicular cuts on tubing, pipe, and sheet metal
• Compatible with almost all metals including stainless steel, mild steel, and aerospace alloys

Compatibility

Designed for use with standard right-angle grinders and cut-off tools that accept 3-inch diameter 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 of cut-off wheels should be performed by qualified tradespeople following the tool and wheel manufacturer safety guidelines. Always power down and disconnect the grinder or cut-off tool before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never operate above the rated RPM marked on the wheel or its packaging. Eye protection, gloves, and appropriate PPE are required during cutting operations.
