Norton 662529-40148 Type 27 Grinding Wheel 7x1/4x5/8-11

Product Description

The NORTON 662529-40148 is a Type 27 depressed-center grinding wheel designed for aggressive material removal with reduced wheel wear over the service life of the disc. Constructed from aluminum oxide abrasive, it is suited for grinding ferrous metals including steel and iron. The 7-inch diameter and 1/4-inch thickness make it a standard choice for angle grinder work in fabrication, construction, and mechanical service applications. Licensed tradespeople and experienced fabricators rely on this wheel where consistent stock removal and extended wheel life matter on the job.

This grinding wheel is intended for use on 7-inch angle grinders and compatible right-angle grinders operating within the rated RPM range. It is well suited for weld grinding, surface preparation, and deburring operations on structural steel, pipe, plate, and similar ferrous workpieces. The 5/8-11 threaded arbor is the standard mounting interface for most 7-inch angle grinders used in commercial and industrial trade settings. Minimum order quantity is 10 wheels per order.
