Norton 66253364339 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253364339 is a Type 1 surface grinding wheel engineered for precision 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 cutting action and free-cutting performance at coarse 46 grit. It measures 14 inches in diameter, 1-1/2 inches thick, with a 5-inch arbor hole, and weighs 17.19 pounds. The vitrified bond provides rigidity and porosity that helps clear swarf efficiently during heavy-duty surface grinding operations. Rated at a maximum of 1800 RPM, this wheel is designed for industrial-grade grinders where controlled material removal and flat surface finish are the priority.

This wheel is suited for production and toolroom surface grinding applications in both shop and manufacturing environments. It performs across a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible grinding equipment includes CNC cutting tool machines, cylindrical grinders, and surface grinders. The coarse grade and K hardness rating make it an appropriate choice when aggressive stock removal is needed before finishing passes.

Key Features

• Aluminum oxide abrasive for effective cutting on ferrous and non-ferrous metals
• Vitrified bond construction provides rigidity and open porous structure for swarf clearance
• 46 grit coarse grade suited for high material removal rates
• K hardness rating for medium wheel hardness — resists glazing on softer materials
• Type 1 straight wheel profile, no recess, compatible with standard surface grinder spindles
• Rated to 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

Wheel mounting and dressing should be performed by a qualified grinding machine operator following ANSI B11.9 safety standards and the machine manufacturer's specifications. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Perform a ring test and run the wheel at operating speed for at least one minute in a guarded position before applying it to the workpiece.
