Norton 66253364337 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253364337 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and open grain exposure throughout the wheel life. At 14 inches in diameter, 1-1/2 inches thick, and with a 5-inch arbor hole, this coarse-grade wheel runs at a maximum of 1800 RPM. The 46-grit, J-hardness (medium) specification makes it well suited for aggressive material removal where surface finish tolerances are moderate. Weighing 17.19 pounds, it is a full-size production wheel intended for professional machine shop and industrial applications.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified structure promotes chip clearance and coolant flow, making it effective for both wet and dry grinding operations in production environments. The Series 32A specification identifies the aluminum oxide grain type and bond formulation used in this wheel family.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, repeatable cut rates
• 46 grit, coarse grade with J hardness rating for aggressive material removal
• Porous wheel structure promotes chip clearance and reduces heat buildup
• Compatible with surface grinders, cylindrical grinders, and CNC tool machines
• Rated for a wide material range including stainless, carbon steels, tool steels, aluminum, and cast iron
• No recess, no taper — standard Type 1 flat wheel geometry

Compatibility

Suitable for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Appropriate 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 machine operator or toolroom technician in accordance with ANSI B7.1 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before installing or removing the wheel. Never exceed the rated maximum speed of 1800 RPM.
