Norton 66252838464 Type 27 Grinding Wheel 5in 36 Grit

Product Description

The NORTON 66252838464 is a Type 27 depressed center grinding wheel designed for aggressive material removal in metalworking and fabrication applications. Built with a ceramic alumina abrasive and resinoid bond, it delivers consistent cutting action at a coarse 36 grit rating. The wheel measures 5 inches in diameter with a 1/16 inch thickness and a 7/8 inch arbor hole. It is rated for a maximum of 12,225 RPM, making it compatible with standard angle grinders. Licensed tradespeople and fabricators working in structural steel, weld prep, and surface conditioning will find this wheel suited for high-stock-removal tasks.

This wheel is intended for use with angle grinders in industrial, commercial, and heavy trade environments. Its Type 27 flat profile is well suited for surface grinding and weld blending on flat or slightly contoured workpieces. The ceramic alumina grain stays sharp longer than standard aluminum oxide, reducing wheel wear during extended grinding sessions. It is a non-flexible wheel, making it appropriate for rigid grinding rather than cutting or flexible finishing work.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following all applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and disconnect the angle grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never exceed the rated maximum RPM. Ensure the guard is properly in place before operating the grinder.
