Norton 66252940895 Surface Grinding Wheel 80 Grit 7 in

Product Description

The NORTON 66252940895 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of ferrous and non-ferrous metals. It measures 7 inches in diameter and 1/2 inch thick, with a 1-1/4 inch arbor hole. The abrasive is aluminum oxide bonded in a vitrified bond matrix, rated at medium grade (hardness code I) with an 80 grit cut. Specification designation is 32A80-IVBE. Rated at a maximum of 3,600 RPM, this wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It weighs 1.59 pounds.

This wheel is appropriate for medium-duty grinding applications in both production and toolroom environments. It performs on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified structure promotes cool cutting and chip clearance, making it a practical choice for flat surface work and form grinding where consistent finish and dimensional accuracy are required. Licensed grinder operators and toolroom machinists are the typical end users.

Key Features

• Aluminum oxide abrasive with vitrified bond for cool, consistent cutting action
• 80 grit medium grade — balanced material removal rate and surface finish
• Hardness code I (medium) resists loading on a broad range of metals
• Porous wheel structure improves chip clearance and reduces heat buildup
• 1-1/4 inch arbor hole fits standard surface and cylindrical grinder spindles
• 3,600 RPM maximum operating speed for safe use on rated machines

Compatibility

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

Installation Notes

Wheel mounting and dressing should be performed by a qualified machine operator following ANSI B7.1 safety standards for abrasive wheel use. Always power down and lockout the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation using the ring test, and verify that the machine spindle speed does not exceed the 3,600 RPM maximum rating stamped on the wheel. Use appropriate flanges and blotters per the grinder manufacturer specifications.
