Norton 66253262689 Surface Grinding Wheel 12in 60 Grit

Product Description

The NORTON 66253262689 is a Type 1 surface grinding wheel built for demanding material removal on ferrous and non-ferrous metals. It measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and weighs 9.045 pounds. The wheel uses an aluminum oxide abrasive bonded with a vitrified bond matrix, delivering consistent stock removal and a predictable wear pattern. Hardness code K and a medium grade classification place it in a mid-range wheel that balances wheel life against cut rate. Maximum operating speed is 2,070 RPM. The gray, non-tapered, porous wheel body promotes coolant flow and chip clearance during grinding passes. This wheel is intended for installation and use by qualified grinding machine operators and tool room professionals.

This wheel is suited for surface grinding and cylindrical grinding applications across a broad range of materials. Rated material applications include 400 series stainless, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. It fits production tool rooms, maintenance shops, and machine shops where consistent flat or cylindrical stock removal is required on mixed material work.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, open cutting action
• 60 grit, K hardness, medium grade — effective balance of cut rate and wheel life
• Porous wheel structure promotes coolant penetration and reduces heat buildup
• Rated for 400 series stainless, carbon steels, tool steels, aluminum, and iron grades
• Type 1 flat wheel profile with no recess — mounts directly to standard surface grinder spindles
• Maximum operating speed of 2,070 RPM

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines requiring a Type 1, 12-inch diameter wheel with a 3-inch arbor hole. Rated for 400 Series Stainless, Hard Carbon Steels, Soft Carbon Steels, Tool Steels, Aluminum, Cast Iron, Ductile Iron, and Gray Iron.

Installation Notes

Installation should be performed by a qualified machine operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the maximum rated RPM of 2,070 stamped on the wheel blotter.
