Norton 07660788245 Bench Grinding Wheel 6in Aluminum Oxide

Product Description

The NORTON 07660788245 is a Type 1 bench and pedestal grinding wheel designed for aggressive stock removal on ferrous metals and general-purpose tool sharpening. It measures 6 inches in diameter, 3/4 inches thick, with a 1-inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, producing a rigid, porous-free structure that holds its shape under sustained grinding pressure. Rated at a maximum of 4,140 RPM, it carries a coarse 36/46 dual-grit specification suited for rapid material removal rather than fine finishing work. A bushing is included to accommodate smaller spindle sizes.

This wheel is appropriate for bench grinders and pedestal grinders used in maintenance shops, fabrication facilities, and trade environments. The coarse 36/46 grit makes it well suited for deburring, rough shaping, and restoring edge geometry on tools such as chisels, drill bits, and lathe tools. It is typically installed by maintenance technicians, machinists, and trade professionals performing routine tool-room grinding tasks.

Designed as a standard Type 1 replacement wheel for 6-inch bench grinders and pedestal grinders with a 1-inch or reducible arbor; bushing included to fit smaller spindle diameters.

Installation Notes

Grinding wheel installation must be performed with the grinder fully powered down and unplugged. Always perform a ring test by tapping the wheel with a non-metallic mallet before mounting — a clear ring indicates an intact wheel; a dull thud indicates a crack and the wheel must not be used. Ensure the operating speed of the grinder does not exceed the 4,140 RPM maximum rating marked on this wheel. Replace the wheel guard before restoring power, and allow the wheel to run for at least one minute at operating speed with no load before beginning work, following ANSI B7.1 safety requirements.
