Norton 66253044161 Surface Grinding Wheel 46 Grit 8in

Product Description

The NORTON 66253044161 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals in industrial grinding applications. Built with an aluminum oxide abrasive grain and a vitrified bond, this wheel carries a coarse 46 grit rating and a J hardness code, placing it in the medium hardness range. It measures 8 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole, and is rated to a maximum of 3600 RPM. The 32A46-JVBE specification identifies the exact bond and grade combination. Licensed tradespeople and industrial machinists install this wheel on compatible surface and cylindrical grinders.

This wheel suits a range of production and maintenance grinding tasks on hard and soft carbon steels, 400 series stainless steel, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse grit and vitrified bond combination supports aggressive material removal while maintaining wheel integrity under repeated dressing cycles. Typical installations include tool rooms, maintenance shops, and production grinding cells.

Key Features

• Aluminum oxide abrasive grain suited for ferrous and select non-ferrous materials
• Vitrified bond provides rigidity and allows consistent dressing for precise form control
• 46 grit coarse grade for high material removal rates
• J hardness (medium) balances wheel wear against workpiece bite
• Porous structure promotes coolant flow and chip clearance during grinding
• Rated to 3600 RPM maximum operating speed

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel installation and dressing must be performed by qualified personnel following applicable ANSI B11 and OSHA 1910.215 standards for abrasive wheel machinery. Before mounting, inspect the wheel for cracks or chips using the ring test, and verify that the machine spindle speed does not exceed the 3600 RPM rating marked on the wheel. Always use proper flanges and blotters, and allow the wheel to run at operating speed in a guarded area before bringing it into contact with the workpiece. Disconnect and lock out power to the grinder before removing or installing any wheel.
