Norton 66252942211 Surface Grinding Wheel 46 Grit Type 5

Product Description

The NORTON 66252942211 is a Type 5 surface grinding wheel designed for use on surface grinders and cylindrical grinders in professional metalworking environments. It is constructed from aluminum oxide abrasive with a vitrified bond and carries a coarse grade rating at 46 grit with an I hardness code. The wheel measures 7 inches in diameter and 3/4 inches thick with a 1-1/4 inch center hole. A one-sided recess of 1/4 inch depth and 2-3/4 inch recess diameter is built into the wheel profile. Rated to 3600 RPM maximum, this wheel is suited for material removal tasks on ferrous and non-ferrous metals. It weighs 2.28 pounds and is manufactured under the 32A series specification.

This grinding wheel is intended for use on surface grinders and cylindrical grinders in commercial and industrial shop environments. It is well suited for tool rooms, maintenance shops, and production grinding operations. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Machinists, tool and die makers, and metal fabricators are the typical end users for this wheel type.

Installation Notes

This wheel should be installed by a qualified machinist or grinding equipment operator. Always inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 safety standards. Ensure the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Use the correct flanges and blotters as required by the grinder manufacturer, and never force the wheel onto the spindle arbor.
