Norton 66253364247 Surface Grinding Wheel 14in 60 Grit

Product Description

The NORTON 66253364247 is a Type 1 straight surface grinding wheel built for precision stock removal on a range of ferrous metals. Manufactured from aluminum oxide abrasive in a vitrified bond matrix, this wheel carries a 60-grit, medium-grade specification suited for controlled material removal without excessive surface damage. The wheel measures 14 inches in diameter, 1-1/2 inches thick, with a 5-inch arbor hole, and is rated to a maximum of 1800 RPM. At 17.19 pounds, it is a substantial wheel intended for stationary surface grinding applications. The internal specification designation is 38A60-IVBE. Licensed grinding technicians and machining professionals are the primary installers and operators of this wheel.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its aluminum oxide composition and medium hardness rating make it well-suited for grinding soft carbon steels, tool steels, and super alloys. The vitrified bond provides rigidity and form-holding capability, making it a reliable choice for flat surface work and precision profile grinding in both job shop and production machining environments.

Key Features

• Type 1 straight wheel profile with no recess, compatible with standard surface grinder spindle setups
• Aluminum oxide abrasive, semi-friable grade, for consistent cutting action on ferrous metals
• Vitrified bond construction provides rigidity and maintains wheel form under repeated passes
• 60-grit medium grade balances material removal rate with acceptable surface finish
• Non-porous, non-tapered wheel geometry for predictable, uniform grinding contact
• White wheel color aids visual inspection for loading, glazing, or uneven wear

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for soft carbon steels, tool steels, and super alloys per manufacturer specification.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 requirements. Before mounting, inspect the wheel for cracks or chips using the ring test. Always confirm the machine spindle speed does not exceed the 1800 RPM maximum rating marked on the wheel. Use proper flanges and blotter materials when securing the wheel to the spindle arbor, and dress the wheel before initial use to true the running surface.
