Norton 66252942701 Surface Grinding Wheel 7in 60 Grit

Product Description

The NORTON 66252942701 is a Type 5 surface grinding wheel built for demanding material removal on ferrous and non-ferrous metals. It features an aluminum oxide abrasive grain bonded in a vitrified bond matrix, producing consistent cutting action and predictable wheel breakdown. The wheel measures 7 inches in diameter and 1 inch thick, with a 1-1/4 inch arbor hole and a one-side recess of 0.5 inches deep by 2.75 inches in diameter. Rated at a maximum of 3,600 RPM, this wheel carries a 60 grit, J hardness (medium grade) specification, identified by the wheel spec code 32A60-JVBE. It is suited for use on surface grinders and cylindrical grinders.

This wheel is designed for production and maintenance grinding of a wide range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Type 5 recessed profile allows clearance for flanges on compatible spindle setups, making it well-suited for both automated surface grinder applications and manual precision grinding work in machine shops and fabrication environments.

Key Features

• Aluminum oxide abrasive for versatile ferrous and non-ferrous material removal
• Vitrified bond provides rigidity, porosity, and consistent cutting performance
• Type 5 one-side recessed wheel design for flange clearance on grinder spindles
• 60 grit medium grade delivers a balance of stock removal and surface finish
• J hardness rating (medium) suits a broad range of workpiece hardnesses
• Porous structure aids coolant flow and chip clearance during grinding

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.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machinist or grinding technician following ANSI B7.1 safety standards. Always power down and de-energize the grinder before mounting or removing wheels. Inspect the wheel for cracks or chips before installation and perform a ring test per standard practice. Never exceed the 3,600 RPM maximum speed rating marked on the wheel.
