Norton 66252838173 Surface Grinding Wheel 80 Grit 6in

Product Description

The NORTON 66252838173 is a Type 1 straight surface grinding wheel designed for precision material removal on a wide range of metals and hard materials. Built to the 39C series specification, it uses a silicon carbide abrasive bonded in a vitrified matrix, producing a free-cutting action well suited to non-ferrous metals, stainless steel, and masonry surfaces. The wheel measures 6 inches in diameter by 1 inch thick with a 1-1/4 inch arbor hole, runs at a maximum of 4140 RPM, and carries an I hardness code rated as medium grade. The green-colored wheel is non-porous with no recess and no taper, making it straightforward to mount and dress. Machinists, tool-and-die technicians, and CNC maintenance personnel are the primary installers.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job-shop and production environments. The 80 grit, medium-grade combination delivers a balance of stock removal rate and surface finish quality. Typical applications include grinding 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Its vitrified bond provides good form-holding under moderate to heavy grinding passes, making it a practical choice for flat surface work and light cylindrical operations where consistent cut geometry is required.

Key Features

• Silicon carbide abrasive for effective cutting on non-ferrous metals, stainless steel, and masonry
• Vitrified bond construction holds wheel form and resists loading during continuous grinding passes
• 80 grit medium grade balances material removal rate with acceptable surface finish
• Type 1 straight wheel profile with no recess and no taper for direct mounting
• 4140 RPM maximum speed rating for surface and cylindrical grinding machine spindles
• Green wheel color conforms to 39C series silicon carbide identification standards

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with a 1-1/4 inch arbor. Suitable for grinding 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment technician. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B11.9 guidelines. Do not exceed the rated maximum RPM of 4140 under any operating condition.
