Norton 66252941036 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 66252941036 is a Type 1 surface grinding wheel designed for precision material removal on ferrous metals in industrial grinding applications. Built with white aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal with semi-friable grain breakdown that maintains a sharp cutting face throughout the wheel life. The wheel measures 7 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole, and is rated to a maximum of 3600 RPM. At medium grade with an I hardness code, it is well suited for controlled surface finishing passes on a range of metallic workpieces. Licensed grinding professionals and tool-room machinists are the primary installers and operators of this wheel.

This grinding wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in industrial and tool-room environments. Material applications include soft carbon steels, tool steels, and super alloys. The 38A series Type 1 profile means it mounts flat to the spindle with no recess, making it a straightforward fit for standard wheel flanges on compatible bench and production grinding equipment. It is appropriate for both single-piece toolroom use and repeat production grinding cycles where consistent surface finish is required.

Key Features

• White aluminum oxide abrasive provides clean, cool cutting action on steels and super alloys
• Vitrified bond holds grain securely while allowing controlled breakdown at the cutting face
• Semi-friable grain structure self-sharpens during use, extending wheel life between dressings
• 60 grit, medium grade, I hardness code suited for stock removal with moderate surface finish
• Non-porous, non-tapered Type 1 flat wheel profile with no recess for straightforward mounting
• 3600 RPM maximum operating speed rated for standard surface and cylindrical grinding spindles

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. Fits spindles accepting a 1.25-inch arbor hole with standard wheel flanges appropriate for a 7-inch Type 1 wheel.

Installation Notes

Grinding wheel installation must be performed by a qualified operator following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Perform a ring test before mounting to check for cracks, and run the freshly mounted wheel at operating speed behind a guard for at least one minute before bringing it into contact with a workpiece. Never exceed the maximum operating RPM stamped on the wheel.
