Norton 66253044810 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253044810 is a Type 5 surface grinding wheel built for precision stock removal on a wide range of ferrous and non-ferrous metals. It measures 8 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 and 3-1/4 inch diameter. The abrasive is aluminum oxide bonded with a vitrified bond, producing a porous, free-cutting structure rated at medium grade with a K hardness code. Wheel specification is 32A60-KVBE. Rated to a maximum of 3,600 RPM, this wheel is suited for surface grinder and cylindrical grinder use. Weight is 3.88 pounds.

This wheel is designed for use on surface grinders and cylindrical grinders in production and maintenance grinding applications. It performs on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The vitrified bond and porous structure allow coolant penetration and efficient chip clearance, making it effective for both wet and dry surface grinding setups where consistent finish and dimensional control are required.

Key Features

• Type 5 recessed wheel profile with 1/2 inch recess depth and 3-1/4 inch recess diameter for clearance on flanged spindles
• Aluminum oxide abrasive with vitrified bond for rigid, consistent cut
• Porous structure promotes coolant flow and chip clearance during grinding
• 60 grit medium grade suited for stock removal with moderate surface finish
• K hardness code provides firm wheel integrity across a broad range of workpiece materials
• Rated at 3,600 RPM maximum operating speed

Compatibility

Designed for use with surface grinders and cylindrical grinders. Rated for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Installation should be performed by a qualified grinding machine operator or maintenance technician familiar with abrasive wheel safety. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B11.9 or OSHA 1910.215 guidelines. Never exceed the 3,600 RPM maximum speed rating marked on the wheel.
