Norton 69936662082 Surface Grinding Wheel 46 Grit 7in

Product Description

The NORTON 69936662082 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous metals. It measures 7 inches in diameter and 1/2 inch thick, with a 1-1/4 inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond, producing a ruby-colored wheel rated at a coarse 46 grit and I hardness code (medium hardness rating). Rated to a maximum of 3600 RPM, it supports both wet and dry operation. This wheel is a standard specification 48A46-IVBE unit and is intended for use by machinists and tool-and-die professionals on surface and cylindrical grinding equipment.

This grinding wheel is suited for material removal on hard carbon steels, soft carbon steels, and tool steels. Typical applications include surface grinding of workpiece flats and cylindrical grinding of shafts and tooling blanks. It is non-porous and non-tapered, with no recess, making it a straightforward drop-in wheel for compatible spindle arbors. The combination of coarse grit and vitrified bond provides aggressive cutting action with good form retention across production and maintenance grinding tasks in both shop and CNC environments.

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a 1-1/4 inch arbor hole and a 7 inch diameter Type 1 wheel. Suitable for grinding hard carbon steels, soft carbon steels, and tool steels.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 and OSHA 1910.215 grinding safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test per manufacturer guidelines. Power down and lock out the grinder before changing wheels. Never exceed the maximum RPM stamped on the wheel blotter or listed on the wheel itself.
