Norton 66253364074 Surface Grinding Wheel 46 Grit 14 in

Product Description

The NORTON 66253364074 is a Type 1 surface grinding wheel engineered for heavy stock removal on a wide range of ferrous and non-ferrous metals. Built with an aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cutting action and open-pore structure that resists loading during aggressive passes. At 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole, it fits production-grade surface grinders and cylindrical grinders. The coarse 46-grit specification and G hardness rating make it well suited to fast material removal rather than finish grinding. Rated at a maximum of 1800 RPM, it weighs 11.46 pounds. Norton designates this wheel under the 32A46-GVBEP specification.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in job shop and production environments. It performs across a broad material range including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified construction promotes chip clearance and coolant penetration, which reduces heat buildup during prolonged cuts on harder alloys. It is appropriate for both maintenance shops and high-volume grinding operations where wheel life and cut rate are the primary considerations.

Key Features

• Aluminum oxide abrasive grain for consistent, aggressive stock removal on steel, iron, and aluminum
• Vitrified bond with open porous structure promotes chip clearance and reduces heat buildup
• 46-grit coarse grade removes material quickly; suited to roughing operations rather than finishing
• G hardness rating provides a softer bond that releases dull grains and maintains sharp cutting action
• Type 1 flat wheel profile with no recess; 5-inch hole accommodates standard production grinder arbors
• Norton 32A46-GVBEP specification for traceable quality and consistent lot-to-lot performance

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

Wheel mounting and dressing should be performed by a qualified grinding machine operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Before mounting, inspect the wheel for cracks using the ring test; do not mount a wheel that produces a dull thud. Ensure the machine spindle speed does not exceed the 1800 RPM maximum stamped on the wheel. Use properly sized, clean flange sets with blotters, and never force the wheel onto the arbor.
