Norton 66253246896 Surface Grinding Wheel 12in 46 Grit

Product Description

The NORTON 66253246896 is a Type 7 recessed surface grinding wheel engineered for demanding material removal on ferrous and non-ferrous metals. It is constructed with aluminum oxide abrasive bonded in a vitrified bond matrix, delivering consistent stock removal across a wide range of metals. The wheel measures 12 inches in diameter and 2 inches thick with a 5-inch arbor hole, a two-sided recess configuration, and a recess depth of 0.5 inches and recess diameter of 7.5 inches. Rated at a maximum of 2,070 RPM, it carries an H hardness code and coarse 46-grit designation. Licensed trades and industrial grinding shops rely on this wheel for both wet and dry grinding operations.

This wheel is suited for surface grinders and cylindrical grinders in both shop and industrial settings. Compatible material applications include 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 toolrooms, fabrication shops, and production grinding environments where aggressive stock removal on a broad range of base metals is required in a single wheel specification.

Installation Notes

Grinding wheel mounting and dressing should be performed by qualified personnel following ANSI B11.9 and OSHA 1910.215 guidelines for abrasive wheel machinery. Always inspect the wheel for cracks or damage before mounting and perform a ring test prior to installation. Power down and lock out the grinder before mounting or changing wheels. Never exceed the maximum rated RPM of 2,070 and confirm the machine spindle speed before operating.
