Norton 614636-24505 Vitrified Mounted Wheel W164 38A

Product Description

The NORTON 614636-24505 is a vitrified mounted grinding wheel designed for precision material removal in industrial and trade grinding applications. Built to the W164 shape specification with a 38A Medium abrasive grade, this wheel measures 0.25 inches in diameter and 0.75 inches in thickness. It mounts via a J2 shank style with a 0.125-inch spindle diameter and is rated for a maximum operating speed of 45,900 RPM. Sold in a box of 5, it is suited for machine shops, fabrication environments, and maintenance technicians who require consistent abrasive performance in tight or hard-to-reach areas.

This vitrified mounted wheel is used in die grinders, rotary tools, and spindle-driven machines for tasks such as deburring, port grinding, surface blending, and internal diameter finishing. The W164 shape makes it appropriate for contoured or recessed grinding work where standard bench wheel geometry is impractical. Typical users include machinists, tool-and-die makers, and maintenance professionals working on ferrous metals and similar materials requiring a medium-grade abrasive cut.

Compatibility

Designed for use with die grinders and spindle-driven rotary machines accepting a J2 shank with a 0.125-inch spindle diameter. Always verify machine RPM rating meets or exceeds the wheel maximum speed of 45,900 RPM before installation.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians following applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and de-energize the grinding machine before mounting or removing the wheel. Inspect the wheel for chips or cracks prior to installation and never exceed the rated maximum spindle speed. Proper guards must remain in place during operation.
