Norton 66253246915 Surface Grinding Wheel 46 Grit 14 in

Product Description

The NORTON 66253246915 is a Type 1 vitrified aluminum oxide surface grinding wheel engineered for demanding material removal on ferrous and non-ferrous metals. At 14 inches in diameter, 1 inch thick, and with a 5-inch arbor hole, it runs at a maximum of 2,320 RPM. The 46-grit, J-hardness (coarse grade) specification delivers aggressive stock removal while the vitrified bond maintains wheel integrity under heavy surface grinding loads. Weighing 11.43 pounds, this wheel is built for production-level use in machine shops and tool rooms. Licensed grinding technicians and machinists are the primary installers and operators.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications in both production and job-shop environments. The aluminum oxide abrasive makes it effective across a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It carries the 32A Type 1 series designation and is non-porous with no recess and no taper, making it a straightforward mount for standard surface grinder spindle setups.

Key Features

• Compatible with a wide range of ferrous and non-ferrous materials including stainless, carbon steels, tool steels, and cast iron

Compatibility

Designed for use with 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

Mounting and dressing of grinding wheels should be performed by qualified machine operators or grinding technicians following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always verify the machine spindle speed does not exceed the 2,320 RPM maximum rating marked on the wheel before installation. Inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the rated speed and ensure the wheel guard is properly secured before operation.
