Norton 66253349850 Abrasive Square Tip Plug 24 Grit

Product Description

The NORTON 66253349850 is a Type 18 square tip abrasive plug wheel designed for aggressive material removal on ferrous metals, castings, and hard surfaces. Built with aluminum oxide abrasive at a coarse 24 grit, this plug is engineered for grinding applications where fast stock removal is the priority. It accepts a 5/8-11 threaded arbor and is rated to a maximum of 18,145 RPM, making it compatible with standard angle grinders and die grinders used in fabrication and finishing work. Licensed grinding technicians and metal fabricators typically reach for this type of mounted point when dressing weld seams, removing flash from castings, or grinding into confined areas that flat wheels cannot reach.

This plug wheel is suited for use in industrial and manufacturing environments as well as heavy mechanical service shops. The square tip profile provides flat-face contact on flat or slightly contoured surfaces, making it a practical choice for surface prep, deburring, and weld cleanup on steel and iron components. The coarse 24 grit rating means material removal rate is high, with little emphasis on surface finish refinement. This plug ships as a single unit and is sold in single-piece quantities.

Installation Notes

Mounting and removal of abrasive plug wheels should be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheel use. Always power down and unplug or lock out the grinder before changing mounted points. Inspect the plug for cracks or damage before each use and never exceed the rated maximum RPM of 18,145. Use the appropriate threaded adapter or spindle nut and confirm the wheel is fully seated and secure before operating.
