Norton 66253313966 Surface Grinding Wheel 60 Grit 14in

Product Description

The NORTON 66253313966 is a Type 1 straight surface grinding wheel engineered for precision stock removal on soft carbon steels, tool steels, and super alloys. It measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole. The wheel is made from white aluminum oxide abrasive bonded in a vitrified bond matrix, rated at medium grade with an H hardness code. At 60 grit, it delivers consistent material removal suited to surface grinding applications requiring controlled finish and dimensional accuracy. Rated at a maximum of 1800 RPM, it is installed and operated by qualified grinding machine technicians.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The 38A Type 1 series designation identifies it as a standard straight-profile wheel without recesses or tapers. Primary material applications include soft carbon steels, tool steels, and super alloys, making it a practical choice for tool rooms and production grinding cells working with a range of ferrous and specialty metals.

Key Features

• White aluminum oxide abrasive for consistent cutting action on steels and super alloys
• Vitrified bond provides rigidity and resistance to heat during grinding
• 60 grit medium grade for balanced stock removal and surface quality
• H hardness code with semi-friable abrasive for self-dressing characteristics
• Non-porous, no-recess, non-tapered Type 1 straight profile for broad machine compatibility
• Maximum rated speed of 1800 RPM

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. Verify arbor size, flange specifications, and maximum operating speed against your machine requirements before mounting.

Installation Notes

Grinding wheel installation must be performed by qualified personnel following ANSI B7.1 safety standards. Inspect the wheel for cracks or chips using a ring test before mounting. Power down and lock out the grinder completely before changing wheels. Never exceed the 1800 RPM maximum speed rating marked on the wheel, and always use proper guards and flanges as specified by the machine manufacturer.
