Norton 66253161034 Surface Grinding Wheel 46 Grit 10in

Product Description

The NORTON 66253161034 is a Type 1 surface grinding wheel engineered for high-stock-removal applications on ferrous and non-ferrous metals. It measures 10 inches in diameter, 1 inch thick, and carries a 3-inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond system, giving it consistent cutting action and the structural integrity needed for surface, cylindrical, and CNC tool-machine grinding. Hardness code H and a coarse 46-grit designation make this wheel well suited to aggressive material removal rather than fine finishing. Maximum operating speed is 2,485 RPM. Weight is 6.09 pounds.

This wheel fits surface grinders, cylindrical grinders, and CNC cutting tool machines in both production shop and job-shop environments. It is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous wheel structure promotes coolant flow and chip clearance, reducing heat buildup during extended grinding passes. Typical users include tool-and-die makers, machinist shops, and maintenance technicians working with a wide range of material types.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, repeatable stock removal
• 46 grit, coarse grade — optimized for aggressive material removal on metals
• Porous wheel construction promotes coolant flow and chip evacuation
• H hardness code provides a balance of wheel life and free-cutting action on harder steels
• No recess, no taper — standard Type 1 flat wheel geometry for broad machine compatibility
• Rated for surface grinders, cylindrical grinders, and CNC cutting tool machines

Compatibility

Rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a 10-inch diameter, 1-inch wide, 3-inch arbor hole Type 1 wheel.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or toolroom technician following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Always power down and de-energize the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation — never mount a damaged wheel. Conduct a ring test and run the wheel at operating speed with the guard in place for at least one minute before grinding contact.
