Norton 66252940276 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 66252940276 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals in machine shop environments. It measures 7 inches in diameter, 3/8 inches thick, and carries a 1-1/4 inch arbor hole. The abrasive grain is aluminum oxide, bonded with a vitrified bond in a porous structure, rated at 60 grit and K hardness for medium-grade cutting action. Rated to a maximum of 3600 RPM, this wheel is well suited for surface grinders and cylindrical grinders where consistent finish and wheel integrity under load are required. The 32A60-KVBE specification identifies the full wheel composition for cross-reference purposes.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in industrial and machine shop settings. 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. It is a practical choice for production grinding or toolroom work where a medium-grit aluminum oxide wheel is specified.

Compatibility

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

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel following ANSI B7.1 safety standards. Always inspect the wheel for cracks or damage before mounting and perform a ring test. Power down and lockout the machine before changing wheels, and verify the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Use the correct flanges and blotters as specified by the grinder manufacturer.
