Norton 66252942096 Surface Grinding Wheel 80 Grit 7 in

Product Description

The NORTON 66252942096 is a Type 1 surface grinding wheel engineered for precision stock removal on a range of metals and hard materials. Built on a vitrified bond with a silicon carbide abrasive, it delivers consistent cut rate and wheel integrity across extended grinding sessions. The wheel measures 7 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole, and is rated to 3600 RPM. At 80 grit and J hardness (medium grade), it produces a controlled, moderately fine finish suitable for production and tool-room surface grinding applications.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The silicon carbide abrasive makes it particularly effective on non-ferrous metals and hard, brittle materials. Documented material applications include 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. The wheel series designation is 39C Type 1, specification 39C80-JVMT.

Key Features

• Silicon carbide abrasive for effective grinding of non-ferrous metals, stainless, and hard materials
• Vitrified bond provides rigid wheel structure and consistent cut-rate throughout wheel life
• 80 grit, J hardness (medium grade) balances material removal rate with surface finish quality
• Non-porous, non-tapered Type 1 flat wheel geometry with no recess — straightforward mounting
• 3600 RPM maximum speed rating for standard surface and cylindrical grinder spindles
• Green wheel color for easy abrasive-type identification at a glance

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 per manufacturer application data.

Installation Notes

Installation and dressing of grinding wheels should be performed by a qualified machinist or tool-room technician following ANSI B7.1 safety code for the use, care, and protection of abrasive wheels. Always ring-test the wheel for cracks before mounting and never exceed the rated maximum RPM of 3600. Ensure the spindle speed of the machine is confirmed before mounting, and use proper flanges and blotters as required. Guard the wheel per machine manufacturer specifications before powering on the grinder.
