Norton 66254433505 Unitized Deburring Wheel 3 in Aluminum Oxide

Product Description

The NORTON 66254433505 is a unitized deburring wheel designed for light material removal, edge blending, and surface finishing on metal workpieces. Built with aluminum oxide abrasive at a medium grade and a density rating of 3, this wheel delivers consistent cut and controlled aggression without loading or glazing quickly. The 3-inch diameter and 0.25-inch face width make it well-suited for detail work in tight areas. Unitized construction bonds the abrasive throughout the entire wheel body, so performance remains consistent as the wheel wears down over its service life. Machinists, fabricators, and maintenance technicians commonly use this wheel for deburring drilled holes, chamfering edges, and blending weld seams on steel, stainless, and aluminum.

This wheel fits die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders equipped with a 0.375-inch arbor. Its compact 3-inch diameter and narrow face make it practical for inline and pencil grinder applications where clearance is limited. The medium-density, medium-grade combination suits general-purpose deburring and finishing tasks across fabrication shops, maintenance facilities, and production lines handling ferrous and non-ferrous metal components.

Key Features

• Density 3 unitized construction delivers consistent abrasive action throughout wheel life
• Medium grade balances material removal rate with surface finish quality
• 3-inch diameter and 0.25-inch face width suit confined-space and detail finishing work
• 0.375-inch center hole fits standard die grinder and inline grinder mandrels
• Compatible with multiple grinder types including pencil, straight, and flexible shaft models

Compatibility

Designed for use with die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders. Requires a 0.375-inch arbor or mandrel for proper mounting.

Installation Notes

Installation is performed by qualified machinists or fabricators familiar with abrasive wheel safety. Before mounting, confirm the grinder spindle speed rating meets or exceeds the wheel's rated maximum RPM and that the arbor diameter matches the 0.375-inch center hole. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Follow ANSI B7.1 and the grinder manufacturer's guidelines for wheel mounting, guard requirements, and safe operating procedures.
