Norton 66253160747 Surface Grinding Wheel 46 Grit 10 in

Product Description

The NORTON 66253160747 is a Type 1 vitrified surface grinding wheel designed for material removal on ferrous and non-ferrous metals in precision grinding applications. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal and dimensional accuracy. The wheel measures 10 inches in diameter by 1 inch thick with a 3-inch arbor hole, carries a 46-grit coarse grade, and is rated to a maximum of 2485 RPM. At 6.097 pounds, it is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Licensed grinding professionals and toolroom operators are the typical installers.

This wheel is appropriate for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Its coarse 46-grit specification makes it well matched to aggressive stock removal passes rather than finish grinding. The porous structure of the wheel promotes chip clearance and coolant flow during wet or dry surface grinding operations on production and toolroom equipment.

Key Features

• Aluminum oxide abrasive for broad ferrous and non-ferrous material compatibility
• Vitrified bond provides rigidity and form-holding during precision surface grinding
• 46-grit coarse grade optimized for aggressive stock removal
• H hardness code with soft hardness rating for effective self-dressing action
• Porous wheel structure promotes chip evacuation and reduces heat buildup
• Type 1 flat wheel profile with no recess, compatible with standard surface grinder spindles

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. Series designation is 32A Type 1, specification code 32A46-HVBE.

Installation Notes

Mounting and dressing of grinding wheels must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always perform a ring test before mounting and confirm the spindle RPM does not exceed the 2485 RPM rating marked on the wheel. Power down and lock out the grinder before changing wheels, and use proper flanges and blotters as required. Inspect the wheel for cracks or chips before each use and never exceed the rated speed under any operating condition.
