3M 7100138406 Ceramic Cutoff Wheel 3 in for Steel

Product Description

The 3M 7100138406 is a ceramic abrasive cutoff wheel designed for use with angle grinders in metal cutting applications. At 3 inches in diameter and 0.035 inches thick, this thin-kerf wheel minimizes material loss during cuts. The 1/4 inch arbor hole fits standard small-angle grinders. A resinoid bond holds the ceramic grain matrix together, and the wheel is fiberglass-reinforced for structural integrity at operating speed. Maximum rated speed is 25,465 RPM. The black wheel is suited for cutting steel and stainless steel in fabrication, maintenance, and repair environments. Sold individually with a minimum order quantity of 50 units.

This wheel is intended for cutting steel and stainless steel with a small angle grinder. Its 3 inch diameter and thin 0.035 inch profile make it well suited for tight clearance cuts and detail work where a larger wheel would be impractical. Typical users include metalworkers, pipefitters, HVAC technicians, welders, and maintenance mechanics who need a compact, fast-cutting wheel for ferrous and stainless applications in the field or shop.

Installation Notes

Cutoff wheels must be mounted and operated by personnel familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always verify the grinder speed does not exceed the wheel maximum RPM of 25,465 before mounting. Inspect the wheel for cracks or damage before each use and never use a damaged wheel. Wear appropriate PPE including eye protection and a face shield during operation.
