Norton 66252941041 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 66252941041 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous metals and high-performance alloys. Built on an aluminum oxide abrasive with a vitrified bond, it delivers consistent cut rate and controlled wear across a wide range of surface and cylindrical grinding applications. The wheel measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. At 60 grit with K hardness (medium grade), it strikes a balance between aggressive material removal and acceptable surface finish. Rated to 3600 RPM maximum, it suits production-environment grinders where consistent results are expected. Weight is approximately 1.59 pounds.

This wheel is suited for surface grinding operations on soft carbon steels, tool steels, and super alloys in both shop and production settings. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond structure is porous and semi-friable, which helps the wheel self-dress and maintain sharp cutting action over time, making it a practical choice for high-cycle grinding tasks where wheel condition consistency matters.

Key Features

• Aluminum oxide abrasive for reliable performance on carbon steels, tool steels, and super alloys
• Vitrified bond with porous, semi-friable structure promotes self-dressing and consistent cut rate
• 60 grit, K hardness (medium grade) balances material removal rate with surface finish
• Type 1 flat wheel geometry with no recess and no taper for straightforward mounting
• 3600 RPM maximum speed rating for use on standard production grinders
• Series 38A specification (38A60-KVBE) for precise replacement sourcing

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. The 1-1/4 inch arbor hole and Type 1 flat profile are standard for most bench and surface grinding spindles accepting 7-inch diameter wheels.

Installation Notes

Grinding wheel installation should be performed by a qualified machine operator or maintenance technician following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always perform a ring test before mounting and inspect the wheel for cracks or damage. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Use proper flanges and blotters as required by the grinder manufacturer.
