Norton 66252941018 Surface Grinding Wheel 120 Grit 7in

Product Description

The NORTON 66252941018 is a Type 1 surface grinding wheel engineered for precision stock removal and finishing on metallic workpieces. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention across a wide range of ferrous and non-ferrous metals. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The 120 grit, fine-grade designation makes it well suited for finish grinding passes where surface quality matters. Rated at 3600 RPM maximum, it fits standard surface and cylindrical grinders used in production and toolroom environments.

This wheel is designed for use in metalworking shops, tool and die operations, and machine shops requiring controlled grinding of hard and soft carbon steels, tool steels, stainless steel, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond structure is porous, promoting coolant flow and chip clearance during wet or dry grinding cycles.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous and non-ferrous metals
• Vitrified bond with porous structure for improved chip clearance and coolant flow
• 120 grit fine grade suitable for finish grinding and light stock removal
• Hardness code L, medium hardness rating for balanced wheel life and cut rate
• Type 1 flat wheel geometry with no recess, no taper
• 3600 RPM maximum operating speed

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Series designation 32A Type 1 with specification code 32A120-LVBE.

Installation Notes

Installation should be performed by a qualified machine operator or toolroom technician following applicable ANSI B7.1 safety standards for abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder completely before changing wheels. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
