3M 7100214075 Cut and Grind Wheel 4 in 3/8 in Arbor

Product Description

The 3M 7100214075 is a reinforced resin-bonded cut and grind wheel designed for use on angle grinders in metal fabrication, welding, and maintenance applications. At 4 inches in diameter with a 3/8 inch arbor, this depressed-center wheel handles both cutting and grinding tasks without a wheel change. It is powered by 3M Precision-Shaped Grain, which delivers a fast cut rate and extended abrasive life. The rigid construction allows back gouging, bevel grinding, and general stock removal on mild steel and stainless steel. Licensed trades and metalworkers install this wheel where versatility and reduced downtime between operations matter most.

This wheel is suited for light industrial, fabrication, and field maintenance work involving mild steel and stainless steel. Its depressed-center profile allows it to function as both a standard grinding wheel and a cut-off wheel, making it appropriate for tasks such as back gouging and weld bevel preparation. The wheel requires less operator pressure than conventional abrasive wheels, which helps reduce fatigue during extended use. It is sold individually and fits standard 4-inch angle grinders with a 3/8 inch arbor.

Installation Notes

Wheel mounting and replacement should be performed by a qualified operator following the angle grinder manufacturer's instructions and applicable ANSI B7.1 safety standards. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Ensure the grinder is fully powered down and unplugged before changing wheels. Always use the appropriate guard and personal protective equipment when operating abrasive wheels.
