3M 7100218056 Cut Grind Wheel 7 in 5/8-11 Arbor

Product Description

The 3M 7100218056 is a quick-change cut and grind wheel engineered for dual-purpose use on a single angle grinder. It functions as both a depressed center grinding wheel and a cut-off wheel, eliminating the need to swap wheels when moving between cutting and grinding tasks. At 7 inches in diameter with a 5/8-11 arbor mount, it is sized for standard large-angle grinders used by fabricators, ironworkers, and general tradespeople working on mild steel and stainless steel. The wheel is reinforced resin bonded and powered by 3M Precision-Shaped Grain, delivering fast material removal with less applied pressure than conventional abrasive wheels.

This wheel is suited for fabrication, structural steel work, weld back gouging, and bevel grinding in both shop and field environments. Its rigid construction supports aggressive cutting passes as well as controlled surface grinding without wheel flex. The reduced pressure requirement makes it practical for extended use sessions where operator fatigue is a concern. It is sold individually and fits grinders with a standard 5/8-11 threaded spindle.

Installation Notes

Installation and wheel changes must be performed by a qualified operator following the grinder manufacturer's instructions and ANSI B7.1 safety standards for abrasive wheels. Ensure the grinder is fully powered down and unplugged before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and confirm the grinder's rated RPM meets or exceeds the wheel's maximum operating speed. Always use the appropriate guard for the wheel diameter.
