Norton 66253364341 Surface Grinding Wheel 14in 60 Grit

Product Description

The NORTON 66253364341 is a Type 1 straight surface grinding wheel designed for precision stock removal on ferrous and non-ferrous materials in industrial grinding applications. Built with an aluminum oxide abrasive and a vitrified bond, this wheel measures 14 inches in diameter, 1-1/2 inches thick, and carries a 5-inch arbor hole. The 60-grit, J-hardness (medium grade) specification delivers an efficient cut on a wide range of workpiece materials. Rated at a maximum of 1800 RPM, it is suited for use on surface grinders and CNC cutting tool machines in production and tool room environments. The vitrified bond provides rigidity and consistent performance across extended grinding cycles.

This wheel is used on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and tool room settings. Compatible material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a standard choice for machinists and grinding machine operators who require controlled, repeatable material removal on hardened or difficult-to-grind workpieces. The 32A Type 1 series designation identifies it within the Norton aluminum oxide vitrified bond family.

Key Features

• Type 1 straight wheel profile with no recess — mounts directly to surface and cylindrical grinders
• Aluminum oxide abrasive rated for ferrous metals including stainless, carbon, and tool steels
• Vitrified bond provides rigidity and consistent cut without loading
• 60 grit, J hardness (medium grade) balances cut rate with surface finish quality
• Porous structure supports coolant flow and chip clearance during wet grinding
• Maximum operating speed of 1800 RPM

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 per Norton specification 32A60-JVBE.

Installation Notes

Installation should be performed by a qualified grinding machine operator or machinist following ANSI B7.1 safety standards for abrasive wheel mounting. 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 operating speed of 1800 RPM marked on the wheel or blotter.
