Norton 662530-49045 Type 27 Grinding Wheel 9in Aluminum

Product Description

The NORTON 662530-49045 is a Type 27 depressed-center grinding wheel engineered for aggressive material removal on aluminum. Built with Gemini Aluminum Oxide abrasive, this wheel delivers consistent cut rate and long service life on non-ferrous stock. The 9-inch diameter and 1/4-inch thickness make it well suited to heavy grinding passes, while the 5/8-11 threaded arbor provides a secure mount on standard angle grinders. Maximum operating speed is 6600 RPM. Metal fabricators, welders, and pipefitters routinely reach for this wheel when removing welds, smoothing rough cuts, or reshaping aluminum workpieces.

This grinding wheel is designed for use on aluminum and other non-ferrous materials in fabrication shops, maintenance facilities, and field service environments. The Type 27 depressed-center profile positions the grinding face slightly below the flange plane, improving clearance and operator control during flat and beveled surface work. It mounts on angle grinders fitted with a standard 5/8-11 threaded spindle.
