Norton 66253246911 Surface Grinding Wheel 46 Grit 14 in

Product Description

The NORTON 66253246911 is a Type 1 surface grinding wheel engineered for aggressive stock removal on ferrous and non-ferrous metals. Constructed from aluminum oxide abrasive bonded in a vitrified matrix, it measures 14 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The 46-grit, coarse-grade specification delivers fast cutting action on medium to hard materials, and the I hardness rating maintains consistent wheel integrity under sustained grinding pressure. Rated to 2320 RPM, this wheel is sized for production-level surface and cylindrical grinding applications. Installation and operation are performed by qualified grinding machine operators or maintenance machinists.

This wheel suits industrial and job-shop environments running surface grinders, cylindrical grinders, and CNC cutting tool machines. 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 Series 32A designation identifies it within the NORTON aluminum oxide line, and the blue and gray color coding is consistent with that product family. It is a non-porous, non-tapered, no-recess Type 1 flat wheel appropriate for flat surface stock removal and OD grinding operations.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent cut rate and thermal resistance
• 46 grit coarse grade removes stock quickly on steels, cast iron, and aluminum
• I hardness rating (medium) resists loading while exposing fresh abrasive at appropriate intervals
• Type 1 flat wheel geometry with no recess and no taper for straightforward mounting
• 2320 RPM maximum operating speed — do not exceed in service
• Specification code 46I8V32A provides full wheel identification for documentation and reorder

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.

Installation Notes

Mounting and dressing of grinding wheels must be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation — never mount a damaged wheel. Confirm machine spindle speed does not exceed the 2320 RPM rating marked on the wheel.
