Norton 66253246868 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253246868 is a Type 5 vitrified surface grinding wheel engineered for aggressive stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and rated at a coarse 46 grit with H hardness, it delivers consistent cutting action across a wide range of materials including stainless steel, tool steel, cast iron, and aluminum. The wheel measures 14 inches in diameter and 1.5 inches thick, with a 5-inch arbor hole, a one-side recess depth of 0.5 inches, and a recess diameter of 8 inches. Maximum operating speed is 1,775 RPM. Weighing 11.43 pounds, it is sized for industrial surface and cylindrical grinder applications. The specification code is 46H8V32A.

This wheel is suited for use on surface grinders and cylindrical grinders in production and job-shop environments. It is appropriate for both light-duty maintenance grinding and heavier material removal passes. Compatible material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The blue and gray vitrified bond construction provides consistent wheel breakdown and coolant retention during wet or dry grinding operations.

Installation Notes

Installation and mounting of grinding wheels should be performed by a qualified operator following ANSI B11.9 and applicable OSHA standards for abrasive wheel machinery. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the maximum RPM marked on the wheel, and always use the correct flange size and arbor hardware for a 5-inch hole mount.
