Norton 66253044017 Surface Grinding Wheel 8in 100 Grit

Product Description

The NORTON 66253044017 is a Type 1 surface grinding wheel designed for precision stock removal on a range of ferrous and non-ferrous materials. Built with a silicon carbide abrasive and vitrified bond, this wheel measures 8 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. It carries a 100-grit, fine-grade specification and is rated to 3600 RPM. The vitrified bond provides consistent cut rate and good wheel breakdown characteristics, making it well-suited for flat surface grinding applications in tool rooms and production environments. Licensed HVAC, machining, and maintenance trades rely on this type of wheel for surface grinder work on hard and semi-hard materials.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs across a broad material range including 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. The green silicon carbide formulation in the 39C series is especially effective on non-ferrous metals and hard, brittle materials where a cooler cut is required to prevent workpiece damage or heat distortion.

Key Features

• Silicon carbide abrasive in a vitrified bond for consistent, controlled cut rate
• 100 grit, fine grade for finish grinding and light stock removal
• Type 1 flat wheel profile with no recess, compatible with standard surface grinder chucks
• Rated to 3600 RPM maximum operating speed
• Non-porous, non-tapered construction for uniform contact across the wheel face
• 39C series specification: 39C100-IVMT

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone.

Installation Notes

Mounting and dressing of grinding wheels should be performed by qualified personnel following ANSI B7.1 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to installation. Power down and lock out the grinder before changing wheels. Never exceed the maximum rated RPM of 3600 under any operating condition.
