Norton 66253246880 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253246880 is a Type 5 vitrified surface grinding wheel engineered for heavy stock removal on ferrous and non-ferrous metals. Built around a 32A aluminum oxide abrasive, it delivers consistent cut rate and free cutting action at coarse 46 grit. The wheel measures 14 inches in diameter and 2 inches thick, with a 5-inch arbor hole and a single-side recess measuring 8 inches in diameter and 1 inch deep. Maximum operating speed is 2,320 RPM. Hardness code I places it in the medium range, balancing wheel wear against material cut rate. Weighing 11.43 pounds, this wheel is sized for production surface and cylindrical grinding applications.

This wheel is suited for use on surface grinders and cylindrical grinders in industrial and job-shop environments. Material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46 grit designation makes it a strong choice for rough grinding and rapid material removal passes rather than finish work. The vitrified bond provides rigidity and porosity control appropriate for wet or dry grinding depending on the machine setup.

Key Features

Compatibility

Designed for use with surface grinders and cylindrical grinders. 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

Wheel mounting and dressing should be performed by a qualified grinding machine operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always inspect the wheel for cracks or damage before mounting and perform a ring test. Ensure the machine spindle speed does not exceed the 2,320 RPM maximum marked on the wheel. Power down and lock out the grinder before changing wheels, and use proper flanges and blotters as required by the machine manufacturer.
