Norton 66252939207 Type 27 Depressed Center Wheel 7 in

Product Description

The NORTON 66252939207 is a Type 27 depressed center grinding wheel designed for use with angle grinders in demanding material removal and surface grinding applications. Built with an aluminum oxide abrasive bonded with a resinoid bond, this wheel delivers consistent stock removal on ferrous metals and general-purpose materials. It measures 7 inches in diameter with a 1/8 inch thickness and a 7/8 inch arbor hole, and is rated to a maximum of 8,600 RPM. The wheel is sold individually and is a standard consumable for HVAC fabricators, pipefitters, ironworkers, and general maintenance trades working with steel and similar materials.

This wheel is suited for grinding, blending, and weld cleanup on flat and slightly contoured surfaces. The Type 27 depressed center profile keeps the grinding face at a low angle to the workpiece, making it effective for surface work where a flat or near-flat grinding plane is required. Typical applications include weld seam removal, edge deburring, and surface preparation prior to welding or coating. It is compatible with standard 7 inch angle grinders equipped with a 7/8 inch arbor.
