Norton 66253246876 Surface Grinding Wheel 14in 60 Grit

Product Description

The NORTON 66253246876 is a Type 5 vitrified aluminum oxide surface grinding wheel built for industrial material removal on ferrous and non-ferrous metals. At 14 inches in diameter and 1.5 inches thick with a 5-inch arbor hole, it is sized for heavy-duty surface and cylindrical grinding operations. The wheel carries a 60-grit medium-grade abrasive with a K hardness code and vitrified bond, delivering consistent stock removal on materials ranging from soft carbon steel to cast iron. Maximum operating speed is 2,320 RPM. Total package weight is 11.43 pounds.

This wheel is designed for use on surface grinders and cylindrical grinders in production and maintenance grinding environments. It is suited for shop applications involving 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The one-side recessed profile (Type 5) with an 8-inch recess diameter and 0.5-inch recess depth clears the wheel hub and provides clearance at the work face, making it practical for surface grinding passes where flange clearance is required.

Installation Notes

Installation should be performed by a qualified grinding machine operator or toolroom technician following ANSI B7.1 safe use of abrasive wheels standards. 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 rated RPM of 2,320; verify the machine spindle speed before mounting.
