Norton 66252942699 Surface Grinding Wheel 60 Grit Type 5

Product Description

The NORTON 66252942699 is a Type 5 surface grinding wheel designed for aggressive stock removal on a wide range of ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and long service life under production grinding conditions. It measures 7 inches in diameter and 1 inch thick, with a 1-1/4 inch arbor hole and a one-side recess of 1/2 inch depth at 2-3/4 inches diameter. Rated to a maximum of 3600 RPM, this wheel carries a 60 grit, I hardness (medium grade) designation, making it well-suited for moderate material removal with controlled surface finish. The 32A60-IVBE specification identifies the full abrasive bond system. Installed by machinists and grinding technicians on surface and cylindrical grinders in job shops and production environments.

This wheel is applicable across 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. It is intended for use on surface grinders and cylindrical grinders. The Type 5 recessed wheel profile provides clearance for the flange and spindle assembly, which is common in pedestal and surface grinder setups where wheel-to-workpiece contact area needs to be managed. The gray, porous structure of the wheel supports coolant penetration and chip clearance during wet or dry grinding operations.

• Vitrified bond construction for rigidity and thermal stability during grinding
• Type 5 one-side recessed profile accommodates standard surface and cylindrical grinder flanges
• 60 grit, medium grade (hardness code I) balances cut rate and surface finish
• Porous structure aids coolant flow and chip evacuation
• Rated to 3600 RPM maximum operating speed

Compatibility

Designed for use with surface grinders and cylindrical grinders. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron, as specified by the manufacturer for this wheel.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding technician. Always power down and de-energize the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B11.9 or applicable safety standard. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
