Norton 66253246914 Surface Grinding Wheel 14in 46 Grit

Product Description

The NORTON 66253246914 is a Type 1 vitrified aluminum oxide surface grinding wheel engineered for aggressive stock removal on ferrous and non-ferrous metals. The wheel measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole. At 46 grit coarse grade with an I hardness rating and a 2320 RPM maximum speed rating, it delivers consistent cut rates on production grinding applications. The vitrified bond provides rigidity and porosity control suited to surface and cylindrical grinding operations. Total package weight is 11.43 pounds.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. It is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse grit and medium hardness combination makes it a practical choice for high-removal passes where surface finish is secondary to material removal rate.

Key Features

• 46 grit coarse grade aluminum oxide abrasive for aggressive stock removal
• I hardness (medium) vitrified bond resists loading on a wide range of metals
• Type 1 straight wheel profile with no recess — fits standard surface and cylindrical grinder spindles
• 2320 RPM maximum speed rating for safe operation on compatible machines
• Non-porous construction maintains consistent wheel geometry through the grind
• Rated for 400 series stainless, carbon steels, tool steels, aluminum, and cast and ductile iron

Compatibility

Rated 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 operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or damage before mounting and perform a ring test. Power down and lockout the grinder before installing or changing wheels. Never exceed the 2320 RPM maximum speed marked on the wheel.
