3M 7100218043 Cut Grind Wheel 9 Inch 5/8-11 Arbor

Product Description

The 3M 7100218043 is a quick-change cut and grind wheel designed for metal fabrication and welding applications. This 9-inch diameter wheel mounts on a 5/8-11 arbor and functions as both a depressed-center grinding wheel and a cut-off wheel in a single tool. Built with a rigid reinforced resin bond and powered by 3M Precision-Shaped Grain, the wheel delivers fast material removal and extended abrasive life. It requires less operator pressure than traditional abrasive wheels, which reduces fatigue during extended use. Each wheel ships individually and is suited for professional metalworking environments.

This wheel is engineered for cutting and grinding on mild steel and stainless steel. Typical applications include back gouging, bevel grinding, and general weld prep work. The quick-change design allows the operator to switch between cutting and grinding tasks without swapping wheels, reducing downtime on the job. It fits standard large-angle grinders equipped with a 5/8-11 threaded spindle, making it compatible with equipment commonly found in fabrication shops, structural steel work, and pipe fitting operations.

• 3M Precision-Shaped Grain delivers fast cut rate and long abrasive service life
• Reinforced resin bond construction provides rigidity under load
• Requires less pressure than conventional wheels, reducing operator fatigue
• Rated for mild steel and stainless steel cutting and grinding
• 9-inch diameter with 5/8-11 arbor for compatibility with standard large-angle grinders

Compatibility

Designed for use on large-angle grinders with a 5/8-11 threaded spindle. Suitable for mild steel and stainless steel workpieces in fabrication, welding, and structural applications.

Installation Notes

Wheel mounting and operation should be performed by qualified personnel following the grinder manufacturer's instructions and applicable ANSI B7.1 safety standards. Inspect the wheel for cracks or damage before each use and never operate above the rated RPM marked on the wheel. Power down and disconnect the grinder before mounting or removing the wheel. Always use appropriate guarding and personal protective equipment when operating abrasive wheels.
