Norton 66252836816 Surface Grinding Wheel 6in 80 Grit

Product Description

The NORTON 66252836816 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 grain and a vitrified bond, it measures 6 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The wheel carries an 80 grit, medium grade specification and is rated to a maximum of 4140 RPM. It weighs 0.75 pounds and features a non-porous, green-colored wheel body. Licensed tradespeople and skilled machinists typically reach for this wheel when they need consistent, controlled cutting action on hard-to-grind materials.

This wheel is suited for surface grinding applications in both production and tool-room environments. It handles a broad range of materials including 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Compatible equipment includes CNC cutting tool machines, cylindrical grinders, and surface grinders. Its medium grade and vitrified bond make it a practical choice when both cut rate and workpiece finish quality matter.

Key Features

• Silicon carbide abrasive grain — effective on hard, brittle, and non-ferrous materials
• Vitrified bond provides rigidity and consistent grain exposure throughout the wheel life
• 80 grit, medium grade balances material removal rate with surface finish quality
• Rated to 4140 RPM maximum for safe use on standard surface and cylindrical grinders
• Non-porous, Type 1 flat wheel geometry — no recess, no taper, straightforward mounting
• Series 39C specification (39C80-IVMT) for traceability and replacement ordering

Compatibility

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

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or tool-room technician following ANSI B11.9 safety standards for grinding machines. Before mounting, inspect the wheel for cracks or chips using a ring test — do not install a damaged wheel. Ensure the machine spindle speed does not exceed the 4140 RPM maximum rating stamped on the wheel. Power down and lock out the machine before changing wheels, and allow the wheel to reach full operating speed before bringing it into contact with the workpiece.
