Norton 66253246794 Surface Grinding Wheel 14in 60 Grit

Product Description

The NORTON 66253246794 is a Type 1 straight-profile surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. Built on an aluminum oxide abrasive with a vitrified bond, the wheel runs at a maximum of 2320 RPM and carries a J hardness code with a medium grade designation. At 14 inches in diameter, 1 inch thick, and bored to a 5-inch hole, it fits standard surface grinder spindle configurations. Weighing 11.43 pounds, this wheel is sized for production-floor and tool-room work performed by machinists and grinding technicians. The Series 32A vitrified bond provides consistent grain exposure across the wheel face for repeatable finish results.

This wheel is suited for surface grinding applications on a wide range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. Typical use cases include flat surface finishing, tool steel reconditioning, and production grinding in both job shop and industrial environments where consistent grit exposure and wheel integrity are required.

Key Features

• Aluminum oxide abrasive for broad metal compatibility including stainless, carbon steels, and cast iron
• Vitrified bond provides rigid grain support and consistent cut rate throughout wheel life
• 60 grit medium grade for balanced stock removal and surface finish
• J hardness code offers moderate wheel hardness suitable for a range of workpiece materials
• Non-porous, non-tapered Type 1 profile with no recess for straightforward mounting
• Maximum operating speed of 2320 RPM — do not exceed this rating

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. 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 technician following applicable ANSI B7.1 safety standards for abrasive wheel mounting. Power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before every installation — do not mount a damaged wheel. Confirm that the machine spindle speed does not exceed the 2320 RPM maximum marked on the wheel.
