Norton 66252940888 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 66252940888 is a Type 1 flat surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and long wheel life under production grinding conditions. The wheel measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. At 60 grit with an L hardness code (medium grade), it balances aggressive material removal with controlled surface finish. Rated to 3,600 RPM, it is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The 32A60-LVBE specification identifies this as a Norton 32A series wheel.

This wheel is intended for professional grinding applications in machine shops, tool rooms, and manufacturing environments. It is compatible with a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified bond structure allows for free chip clearance and helps prevent heat buildup during extended grinding passes. Machinists, tool grinders, and maintenance professionals are the primary installers and operators of this wheel.

Installation Notes

Grinding wheel mounting and dressing should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test; never mount a damaged wheel. Ensure the arbor hole size, maximum RPM rating, and wheel dimensions are verified against the machine specifications before use.
