Norton 614636-22366 Square Tip Grinding Plug 2x4in 5/8-11

Product Description

The NORTON 614636-22366 is a square tip grinding plug designed for precision material removal on hard-to-reach surfaces. Classified as Part 18R with a 57A24-R specification, this abrasive plug mounts via a 5/8-11 threaded arbor and measures 2 inches in diameter by 4 inches in length. It is intended for use with angle grinders and compatible grinding equipment in metal fabrication, weld dressing, and surface preparation applications. Licensed tradespeople and skilled fabricators rely on this type of plug for controlled, consistent stock removal in recessed or bore-style workpieces.

This grinding plug is suited for shop and field use in metalworking environments where standard wheel geometry will not access the work area. The square tip profile concentrates abrasive contact at the leading face, making it effective for flat-bottom bore grinding and cavity work. It is sold individually and is appropriate for both production grinding and maintenance applications in manufacturing, welding, and general metal finishing.

Key Features

• Square tip geometry for flat-bottom bore and cavity grinding
• 5/8-11 threaded arbor mount for compatibility with standard angle grinders
• 2 inches diameter x 4 inches length for reach into recessed work areas
• 57A24-R abrasive specification for consistent stock removal on ferrous metals
• Part 18R plug form factor for use where disc or cup wheels cannot access

Compatibility

Designed as an OEM-style abrasive plug for use with standard 5/8-11 threaded angle grinder spindles and compatible grinding machines accepting Part 18R plug geometry.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive product safety standards and applicable ANSI B7.1 guidelines. Always power down and disconnect the grinder before mounting or removing the plug. Thread the plug securely onto the 5/8-11 spindle and verify the abrasive is rated at or above the tool RPM before operating. Inspect the plug for cracks or damage before each use and do not exceed the maximum operating speed marked on the product.
