Norton 66253007162 Surface Grinding Wheel 8in 46 Grit

Product Description

The NORTON 66253007162 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous metals in surface grinding and cylindrical grinding applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and form stability under repeated use. It measures 8 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. The 46-grit, coarse-grade specification makes it well suited for aggressive material removal rather than fine finishing. Rated at a maximum of 3,105 RPM, it is sized and dressed for production environments where reliable geometry and safe operating speed are essential. Licensed grinding machine operators and tool room technicians are the primary installers and users of this wheel.

This wheel is rated for use on hard carbon steels, soft carbon steels, and tool steels. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond structure is porous, which promotes coolant flow and chip clearance during wet or dry grinding operations. The Series 32A Type 1 designation identifies the wheel's internal specification code as 32AA46-IVTRP, providing a direct reference point when cross-referencing shop orders or replacement wheels in a production tool crib.

Key Features

• Aluminum oxide abrasive for effective grinding of carbon steels and tool steels
• Vitrified bond with porous structure supports coolant flow and chip evacuation
• 46-grit coarse grade optimized for high material removal rates
• Type 1 flat wheel geometry with no recess and no taper for straightforward mounting
• Maximum operating speed of 3,105 RPM rated for surface and cylindrical grinder use
• Series specification 32AA46-IVTRP for precise cross-referencing in tool crib records

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for grinding hard carbon steels, soft carbon steels, and tool steels per the manufacturer material application data.

Installation Notes

Grinding wheel installation must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Always power down and lock out the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and verify that the machine spindle speed does not exceed the 3,105 RPM maximum rating stamped on the wheel. Use properly sized flanges and blotters; never force the wheel onto the arbor.
