Norton 66253364323 Surface Grinding Wheel 46 Grit 14 in

Product Description

The NORTON 66253364323 is a Type 1 surface grinding wheel engineered for heavy-stock removal on a wide range of ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and open pore structure that resists loading during aggressive passes. At 14 inches in diameter, 2 inches thick, and a 5 inch arbor hole, it is sized for industrial surface grinders and cylindrical grinding machines. The coarse 46 grit and I hardness code place it firmly in the medium-hard, fast-cutting range. Rated to 1800 RPM maximum, it weighs 22.92 pounds and carries the 32A46-IVBE specification designation.

This wheel is suited for surface grinding operations in machine shops, tool rooms, and production grinding environments. It handles a broad material range including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes CNC cutting tool machines, cylindrical grinders, and surface grinders. Its porous, vitrified structure promotes coolant flow and chip clearance, making it a practical choice for both wet and dry surface grinding setups where material removal rate matters.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, repeatable cut performance
• 46 grit coarse grade designed for high material removal rates
• I hardness code provides medium-hard wheel structure that holds form under load
• Porous wheel construction promotes coolant penetration and reduces heat buildup
• 32A46-IVBE specification for traceability to Norton standard grinding grades
• Rated at 1800 RPM maximum operating speed

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

Grinding wheel mounting and dressing should be performed by a qualified machinist or tool and die technician following ANSI B11.9 and OSHA 1910.215 safety standards for abrasive wheel machinery. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before every installation using the ring test, and never exceed the 1800 RPM maximum speed rating. Ensure flanges, blotters, and arbor hardware are clean, undamaged, and properly seated before running the wheel.
