Norton 66253262696 Surface Grinding Wheel 12in 80 Grit

Product Description

The NORTON 66253262696 is a Type 1 straight surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and good wheel life on surface grinders, cylindrical grinders, and CNC cutting tool machines. It measures 12 inches in diameter, 1 inch thick, with a 5-inch arbor hole. The 80-grit, J-hardness (medium grade) specification suits applications requiring a balance between material removal rate and surface finish quality. Rated at a maximum of 2070 RPM, it is well suited for production grinding environments where controlled wheel wear is a priority.

This wheel is designed for use on surface grinders and cylindrical grinders in both shop and production settings. It performs on 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 structure promotes coolant flow and chip clearance during extended grinding passes, making it a practical choice for production floors and tool rooms where wheel dressing intervals need to be predictable.

Key Features

• Aluminum oxide abrasive for broad metal compatibility including stainless, carbon steels, and cast iron
• Vitrified bond with porous structure for improved coolant flow and chip clearance
• 80 grit, J hardness (medium grade) balances stock removal and surface finish
• Type 1 straight wheel profile with no recess — fits standard surface and cylindrical grinder spindles
• Specification grade 32A80-JVBE for consistent lot-to-lot performance
• Maximum operating speed of 2070 RPM

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 series stainless steel, 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 machinist or grinding machine operator with the machine fully de-energized and locked out before mounting. Always inspect the wheel for cracks or chips before mounting — ring-test per ANSI B7.1 guidelines. Confirm the spindle speed does not exceed the wheel's maximum rated RPM of 2070 before operation. Use proper blotters and flanges as required by machine manufacturer specifications.
