Norton 66253262841 Surface Grinding Wheel 46 Grit 12in

Product Description

The NORTON 66253262841 is a Type 1 surface grinding wheel designed for precision stock removal on a range of ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, it measures 12 inches in diameter, 1 inch thick, with a 5-inch arbor hole. The 46-grit, coarse-grade aluminum oxide delivers aggressive material removal while the vitrified bond maintains wheel integrity under high-heat grinding conditions. Rated at a maximum of 2070 RPM, this wheel is sized for industrial surface grinders and CNC cutting tool machines. Licensed tradespeople and grinding machine operators use this wheel in production and tool-room environments.

This grinding wheel suits surface grinding applications on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse 46-grit specification makes it well suited for aggressive material removal passes rather than finish grinding. The wheel carries the internal specification designation 32A46-GVBEP and belongs to the NORTON 32A Type 1 series.

Key Features

• Aluminum oxide abrasive for effective grinding of steels, cast iron, and aluminum
• Vitrified bond construction provides rigidity and thermal stability during grinding
• 46 grit coarse grade for high material removal rates
• Type 1 flat wheel profile with no recess, compatible with standard surface grinder arbors
• Porous structure promotes coolant flow and chip clearance
• Maximum rated speed of 2070 RPM

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. Specification code 32A46-GVBEP identifies exact wheel composition for cross-reference purposes.

Installation Notes

Mounting and dressing of grinding wheels must be performed by qualified personnel following ANSI B11.9 and applicable shop safety standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each installation using a ring test. Never exceed the maximum RPM stamped on the wheel blotter or listed in the manufacturer documentation.
