3M 7100218279 Cut Grind Wheel 4.5 Inch 5/8-11 Arbor

Product Description

The 3M 7100218279 is a quick change cut and grind wheel designed for metal fabrication and welding work. This 4.5-inch reinforced resin-bonded wheel fits a 5/8-11 arbor and functions as both a depressed center grinding wheel and a cut-off wheel in a single tool. Powered by 3M Precision-Shaped Grain, it delivers a fast cut rate and extended abrasive life. The rigid construction handles back gouging, bevel grinding, and general metal removal without requiring a wheel swap between operations, cutting downtime on the job.

This wheel is suited for cutting and grinding on mild steel and stainless steel in fabrication shops, pipe work, structural steel, and general metalworking environments. The wheel requires less operator pressure than conventional bonded abrasive wheels, which reduces fatigue during extended use. It is packaged individually and is part of the 3M Advanced Series Abrasives line, offering a balance of performance and cost efficiency for production and maintenance applications.
