Norton 66252941008 Surface Grinding Wheel 7in 100 Grit

Product Description

The NORTON 66252941008 is a Type 1 surface grinding wheel engineered for precision flat-surface stock removal on a wide range of ferrous and non-ferrous metals. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The abrasive is aluminum oxide with a vitrified bond, rated at a medium hardness (J hardness code) and a fine 100-grit grade. The wheel specification designation is 32A100-JVBE. It is rated to a maximum of 3600 RPM. The porous structure of the wheel assists with chip clearance and coolant flow during extended grinding passes.

This wheel is suited for surface grinding operations on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The fine 100-grit grade makes it appropriate for finishing passes where tight surface finish tolerances are required rather than aggressive material removal.

Key Features

• Aluminum oxide abrasive for consistent cut on ferrous and non-ferrous metals
• Vitrified bond provides rigid structure and controlled wear rate
• J hardness (medium) balances wheel life with cutting action across a range of workpiece hardnesses
• 100 grit fine grade suited for finish grinding and close-tolerance surface work
• Porous wheel structure aids coolant penetration and swarf evacuation
• Maximum 3600 RPM rating — verify spindle speed before mounting

Compatibility

Designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for material applications including 400 series stainless, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Part of the NORTON 32A Type 1 series.

Installation Notes

Grinding wheel installation must be performed by a qualified machine operator or maintenance professional following ANSI B7.1 safety standards. Power down and lock out the grinder before mounting or removing any wheel. Always perform a ring test before installation and run the wheel at operating speed with the guard in place for at least one minute before engaging the workpiece. Never exceed the maximum RPM stamped on the wheel.
