Norton 66252942697 Surface Grinding Wheel 60 Grit 7in

Product Description

The NORTON 66252942697 is a Type 5 surface grinding wheel engineered for aggressive stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 7 inches in diameter, 1 inch thick, with a 1-1/4 inch bore. The 32A series specification (32A60-HVBE) identifies a medium-grade, H-hardness wheel rated to 3600 RPM. The porous, vitrified structure promotes cool cutting and consistent performance across extended grinding sessions. At 2.6 pounds, it fits standard surface and cylindrical grinders equipped with a 1-1/4 inch arbor. Licensed machinists, tool-and-die technicians, and grinding specialists are the primary installers and operators of this wheel.

This wheel is suited for precision surface grinding applications in job shops, maintenance facilities, and manufacturing environments. It handles a broad range of material types including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders and cylindrical grinders. The one-side recessed profile (recess depth 0.5 inches, recess diameter 2.75 inches) allows clearance for flanges and mounting hardware on appropriate spindle configurations.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, cool cutting action
• Type 5 one-side recessed wheel geometry for flange clearance on compatible grinders
• 60 grit, H hardness (medium grade) for balanced material removal and wheel life
• Rated to 3600 RPM maximum operating speed
• Porous wheel structure aids chip clearance and reduces heat buildup
• Covers a wide material range including stainless, carbon steels, tool steels, aluminum, and cast iron

Compatibility

Designed for use with surface grinders and cylindrical grinders accepting a 1-1/4 inch arbor bore. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron workpieces.

Installation Notes

Grinding wheel mounting must be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always ring-test the wheel before mounting and inspect for cracks or damage. Never exceed the maximum rated speed of 3600 RPM. Power down and lock out the grinder before changing wheels, and use proper flanges and a blotter gasket as required by the grinder manufacturer.
