Norton 66252942666 Surface Grinding Wheel 60 Grit 7in

Product Description

The NORTON 66252942666 is a Type 1 surface grinding wheel built for demanding material removal on hard and non-ferrous metals. It measures 7 inches in diameter and 1 inch thick with a 1-1/4 inch arbor hole. The wheel is made from silicon carbide abrasive bonded with a vitrified bond system, producing a hard, consistent cutting action rated at 60 grit and I hardness (medium grade). It is rated to a maximum of 3,600 RPM. This wheel suits machine shops, fabrication environments, and trade professionals who need reliable stock removal on a range of ferrous and non-ferrous workpiece materials.

This grinding wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 300 Series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. It is well suited to production grinding operations where a consistent, medium-grade silicon carbide wheel is required. The non-porous, non-tapered, non-recessed Type 1 profile makes it a straightforward drop-in for standard surface grinding spindle setups.

Key Features

• Silicon carbide abrasive grain for effective cutting on non-ferrous metals, stainless steel, and masonry
• Vitrified bond provides rigid wheel structure and consistent grit exposure throughout wheel life
• 60 grit medium grade (I hardness) delivers balanced stock removal and surface finish
• 3,600 RPM maximum rated speed for safe operation on compatible equipment
• Type 1 flat-wheel profile with no recess and no taper for straightforward mounting
• Green wheel color consistent with silicon carbide series identification

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. Part of the NORTON 39C Type 1 series, specification 39C60-IVMT.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment operator following all machine manufacturer guidelines and ANSI B7.1 safety standards for abrasive wheel mounting. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Ensure the machine spindle speed does not exceed the 3,600 RPM maximum rating stamped on the wheel. Power down and lock out the grinder before changing wheels, and use the correct flanges and blotters for the 1-1/4 inch arbor bore.
