Norton 66252843179 Type 27 Grinding Wheel 4 in 24 Grit

Product Description

The NORTON 66252843179 is a Type 27 depressed center grinding wheel designed for aggressive material removal on angle grinders. It measures 4 inches in diameter with a 0.25-inch thickness and a 3/8-inch arbor hole. The abrasive material is zirconia alumina at a coarse 24 grit, bonded with a resinoid bond and rated to a maximum of 15,280 RPM. The hardness code is S, indicating a firm wheel suited for high-pressure grinding applications. This wheel is commonly used by metal fabricators, pipefitters, ironworkers, and other trade professionals who need fast stock removal on steel and other ferrous materials.

This wheel is intended for use with standard angle grinders that accept a 3/8-inch arbor. The Type 27 depressed center profile keeps the grinding surface slightly elevated from the workpiece, making it well suited for flat surface grinding and weld blending. It is appropriate for both shop and field use in fabrication, construction, and maintenance applications where coarse, high-speed grinding is required.

Compatibility

Designed for use with angle grinders accepting a 3/8-inch arbor connection. The Type 27 profile and arbor size are standard across a wide range of corded and cordless angle grinders used in fabrication and construction trades.

Installation Notes

Installation and wheel changes must be performed by a qualified operator with the grinder powered off and unplugged or battery removed. Always confirm the grinder's rated RPM meets or exceeds the wheel's 15,280 RPM maximum before mounting. Inspect the wheel for cracks or damage before each use and never use a damaged wheel. Follow ANSI B7.1 safety standards for the proper use, handling, and protection of abrasive wheels.
