Norton 66252916222 Surface Grinding Wheel 46 Grit 7in

Product Description

The NORTON 66252916222 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous metals and high-performance alloys. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and shape retention under wet grinding conditions. It measures 7 inches in diameter, 0.5 inches thick, with a 1-1/4 inch arbor hole, and is rated to a maximum of 3600 RPM. At a coarse 46 grit and G hardness code, the wheel is well-suited for aggressive material removal while maintaining controlled surface finish. The semi-friable grain structure allows for self-sharpening behavior during use. Weighing 1.5 pounds, this is a single-unit wheel packaged for individual installation.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs on soft carbon steels, tool steels, and super alloys. Wet operation is supported, making it appropriate for production grinding environments where coolant is applied to extend wheel life and control workpiece temperature. The white aluminum oxide construction under the 38A Type 1 series designation is a common specification in tool room and production grinding applications where precise material removal on harder or heat-sensitive materials is required.

Key Features

• Aluminum oxide abrasive with vitrified bond for shape retention and consistent cut rate
• 46 grit coarse grade for aggressive stock removal
• G hardness rating with semi-friable grain for controlled self-sharpening
• Rated to 3600 RPM maximum operating speed
• Wet operation compatible for use with grinding coolants
• Type 1 flat wheel profile with no recess, no taper
• Specification code 38A46-GVP2 for direct cross-reference

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. Arbor hole size of 1-1/4 inches must match the machine spindle or require an appropriate bushing reducer.

Installation Notes

Grinding wheel installation must be performed by a qualified operator following ANSI B11.9 and applicable shop safety standards. Always perform a ring test before mounting to check for cracks or damage. Power down and lock out the grinder before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel, and verify the machine spindle speed before operation.
