Norton 66253160750 Surface Grinding Wheel 46 Grit 10 in

Product Description

The NORTON 66253160750 is a Type 1 straight surface grinding wheel engineered for high-stock-removal work on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and wheel integrity across sustained surface grinding operations. The wheel measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a 46-grit coarse grade for aggressive material removal. Hardness code I indicates a medium-hard wheel structure that holds its form under moderate grinding pressure. Rated at 2,485 RPM maximum, this wheel suits production-level surface grinding setups where dimensional accuracy and surface finish are both requirements.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. It is rated for use on 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Series 32A vitrified bond construction makes it a dependable choice for shops that cycle through material types without changing wheels. Licensed machinists and grinding specialists are the primary installers and operators.

Material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Series designation is 32A Type 1; wheel specification is 32A46-IVBE.

Installation Notes

Grinding wheel installation must be performed by a qualified machine operator or toolroom technician following ANSI B11.22 and applicable OSHA abrasive wheel standards. Always ring-test the wheel for cracks before mounting and confirm the machine spindle RPM does not exceed the 2,485 RPM maximum rating stamped on the wheel. Power down and lock out the machine before mounting or removing the wheel. Never exceed the rated speed, and always use the correct flanges and blotters for the arbor size.
