Norton 66252941954 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66252941954 is a Type 1 surface grinding wheel engineered for precision material removal on soft carbon steels, tool steels, and super alloys. The wheel measures 7 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole. It uses white aluminum oxide abrasive bonded in a vitrified matrix, producing a coarse, 46-grit cut rated K hardness. The semi-friable grain structure promotes consistent stock removal while minimizing heat buildup. Rated for a maximum of 3600 RPM, this wheel suits production and tool-room environments where dimensional accuracy and surface finish are both priorities.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production settings. Its aluminum oxide composition and vitrified bond make it well-suited for ferrous applications, particularly soft carbon steels, tool steels, and super alloys. The Type 1 flat profile fits standard surface grinder spindles and is appropriate for face and peripheral grinding operations performed by machinists and grinding specialists.

Key Features

• White aluminum oxide abrasive for aggressive, cool cutting on ferrous metals
• Vitrified bond provides rigidity and maintains wheel form during precision grinding
• 46 grit, K hardness, coarse grade for high stock removal rates
• Semi-friable grain structure extends wheel life while controlling heat
• Type 1 flat wheel profile with no recess, non-porous construction
• Maximum operating speed of 3600 RPM for compatibility with standard surface grinder spindles

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. Series designation 38A Type 1 with internal specification 38A46-KVBE.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or grinding specialist. Always power down and lock out the machine before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips before every use and perform a ring test per ANSI B11.9 guidelines. Never exceed the rated maximum RPM of 3600 stamped on the wheel blotter.
