Norton 66253048896 Type 27 Depressed Center Wheel 9 in

Product Description

The NORTON 66253048896 is a Type 27 depressed center grinding wheel engineered for use with angle grinders in demanding material removal and grinding applications. Built with a ceramic alumina abrasive and a resinoid bond, this wheel delivers aggressive stock removal while maintaining consistent cutting performance across its service life. It measures 9 inches in diameter with a 1/8-inch thickness and features a 7/8-inch arbor hole for standard angle grinder spindle mounting. The wheel is rated to a maximum of 6,600 RPM. It weighs approximately 1 pound, making it practical to handle and swap during extended work sessions.

This wheel is suited for metal grinding, weld dressing, and surface preparation in both residential construction and light industrial environments. The Type 27 depressed center profile keeps the wheel hub raised above the work surface, allowing a low grinding angle and improved operator control during flat or contoured surface work. Licensed tradespeople including ironworkers, pipefitters, fabricators, and general contractors commonly specify ceramic alumina wheels for harder metals and high-production grinding where heat buildup and rapid wear are concerns.

Installation Notes

Mounting and operation of grinding wheels should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect or de-energize the angle grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never operate above the marked maximum RPM. Appropriate personal protective equipment including face shield, gloves, and hearing protection is required during operation.
