Norton 66253262691 Surface Grinding Wheel 60 Grit 12 in

Product Description

The NORTON 66253262691 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention across high-cycle production and toolroom applications. It measures 12 inches in diameter, 1 inch thick, with a 5 inch arbor hole, and carries a 60 grit, K hardness (medium grade) specification. The vitrified bond structure is porous, promoting free cutting action and efficient chip clearance. Maximum rated speed is 2705 RPM. Installation is performed by qualified grinding machine operators or maintenance machinists following ANSI B7.1 safety standards.

This wheel is suited for surface grinding operations on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The 12 inch diameter and 5 inch hole sizing position this wheel for mid-to-large capacity production surface grinders common in job shops and manufacturing environments. The 32A60-KVBE specification identifies it within the Norton 32A Type 1 series, a well-established line for precision ferrous grinding.

Key Features

• Aluminum oxide abrasive for effective grinding of steels, cast irons, and aluminum
• Vitrified bond with porous structure for free-cutting action and reduced heat buildup
• 60 grit, K hardness (medium grade) delivers a balance of material removal rate and surface finish
• Type 1 straight wheel profile, no recess, no taper — fits standard surface and cylindrical grinder spindles
• Rated to 2705 RPM maximum operating speed
• Norton 32A series specification: 32A60-KVBE

Compatibility

Designed 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. The 5 inch arbor hole and 12 inch diameter must match the machine spindle and guard specifications before mounting.

Installation Notes

Grinding wheels must be installed by trained personnel following ANSI B7.1 safe practices for the use, care, and protection of abrasive wheels. Always perform a ring test before mounting and inspect the wheel for cracks or chips. Power down and lock out the grinder before changing wheels, and verify the machine RPM rating meets or exceeds the wheel maximum of 2705 RPM before operation. Never exceed the rated maximum speed marked on the wheel.
