Norton 66253246796 Surface Grinding Wheel 14in 60 Grit

Product Description

The NORTON 66253246796 is a Type 1 straight-wheel surface grinding wheel designed for precision stock removal on a broad range of ferrous and non-ferrous metals. Built with an aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention across extended production runs. It measures 14 inches in diameter, 1 inch thick, and carries a 5-inch arbor hole. Rated at a maximum of 2,320 RPM, it is suited for heavy-duty surface grinding applications where dimensional accuracy and wheel durability are both priorities. Weight is 11.43 pounds. Hardness code K and medium grade classify it as a moderately hard wheel that holds its shape well in aggressive grinding passes.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in industrial and shop environments. Typical applications include finish and stock-removal grinding on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is installed and dressed by machinists, tool grinders, and skilled trades personnel operating production or toolroom grinding equipment. The Series 32A designation reflects a well-established aluminum oxide grain specification commonly specified in toolroom and production-grinding environments.

Installation Notes

Grinding wheel mounting must be performed by qualified personnel following ANSI B11.9 and applicable OSHA standards for abrasive wheel machinery. Always ring-test the wheel before mounting and inspect for cracks or damage. Power down and lock out the grinder before changing wheels. Never exceed the maximum RPM rating stamped on the wheel, and always dress the wheel with an appropriate diamond dresser before the first grinding pass.
