Norton 66252941611 Surface Grinding Wheel 7in 60 Grit

Product Description

The NORTON 66252941611 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of metals and hard materials. Built on a vitrified bond with a silicon carbide abrasive, this wheel delivers consistent cut rate and controlled wear on materials including stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, and is rated to a maximum of 3600 RPM. The J hardness code places it in the medium grade range, balancing wheel life against aggressive material removal. Weighing 1.35 pounds, it is a practical bench or machine-mount option for shop and field grinding work.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and maintenance environments. Its silicon carbide grain makes it particularly effective on non-ferrous metals, cast materials, and hard non-metallic surfaces such as masonry and natural stone. The vitrified bond provides a rigid, porous-free structure that holds form well under consistent feed pressure, making it a reliable choice for flat surface work where dimensional accuracy matters. It is used by machinists, tool-and-die workers, and maintenance technicians in industrial and fabrication settings.

Key Features

• Silicon carbide abrasive grain — effective on non-ferrous metals, cast iron, masonry, and natural stone
• Vitrified bond construction — rigid, non-porous structure maintains wheel form under load
• 60 grit, J hardness (medium grade) — balanced stock removal and wheel longevity
• Type 1 flat wheel profile — no recess, no taper, straight-sided geometry
• 3600 RPM maximum speed rating
• Series 39C specification (39C60-JVMT)

Compatibility

Compatible 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. Fits spindles with a 1-1/4 inch arbor hole.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive wheel safety. Power down and lock out the machine before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips before mounting — do not use a damaged wheel. Ensure the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel, and always use appropriate flanges and blotters per ANSI B11 and OSHA 29 CFR 1910.215 requirements.
