Norton 66253044198 Surface Grinding Wheel 60 Grit 8 in

Product Description

The NORTON 66253044198 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. Built with an aluminum oxide abrasive grain and a vitrified bond, it delivers consistent cut rate and wheel life on surface grinders, cylindrical grinders, and CNC cutting tool machines. The wheel measures 8 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole. At 60 grit and G hardness (medium grade), it is suited for moderate material removal where surface finish and dimensional control are both required. Rated at a maximum of 3600 RPM, this wheel is installed by tool room machinists and grinding machine operators in production and maintenance environments.

This wheel is appropriate for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It fits surface grinders and cylindrical grinders with a 1-1/4 inch spindle arbor. The porous, vitrified bond structure promotes coolant flow and chip clearance during wet or dry grinding, making it a practical choice across general-purpose tool room and production grinding applications.

Key Features

• Aluminum oxide abrasive grain suitable for ferrous and non-ferrous workpiece materials
• Vitrified bond with porous structure supports coolant flow and reduces heat buildup
• 60 grit, G hardness (medium grade) balances material removal rate with workpiece finish
• Type 1 flat wheel profile with no recess — direct mount on standard surface grinder spindles
• Series designation 32A60-GVBEP confirms OEM-style Norton specification for tool room traceability
• 3600 RPM maximum operating speed — do not exceed rated RPM

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with a 1-1/4 inch arbor. 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

Grinding wheel mounting and dressing should be performed by a qualified machine operator or tool room technician following ANSI B11.9 and OSHA 29 CFR 1910.215 requirements. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and verify that the machine spindle speed does not exceed the 3600 RPM rating marked on the wheel. Use proper flanges and blotters as required by the machine manufacturer.
