Norton 66253246884 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253246884 is a Type 5 vitrified aluminum oxide surface grinding wheel rated for demanding material removal on ferrous and non-ferrous metals. At 14 inches in diameter and 2 inches thick, this coarse-grade wheel carries a 46 grit, K hardness (Medium) specification and is engineered for use on surface grinders and cylindrical grinders. The vitrified bond provides a rigid, porous-free structure that holds grit securely under load, supporting a maximum operating speed of 2320 RPM. Weighing 11.43 pounds, the wheel mounts on a 5-inch arbor hole and features a one-side recess with an 8-inch recess diameter and 1-inch recess depth. Specification code 46K8V32A confirms grit, hardness, bond, and series.

This wheel is suited for production grinding operations in job shops, tool rooms, and manufacturing environments. Its coarse aluminum oxide abrasive performs across a wide range of materials including 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Type 5 recessed profile accommodates wheel flanges on surface and cylindrical grinder spindles where clearance is required. This is a single-unit package typically sourced by machinists, tool grinders, and industrial maintenance personnel.

Material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel installation and dressing must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test to confirm integrity. Disconnect and lock out power to the grinder before mounting, tightening flanges evenly and never exceeding the rated maximum RPM. A blade or diamond dresser should be used to true and balance the wheel before putting it into service.
