Norton 66254433506 Unitized Deburring Wheel 3 Inch

Product Description

The NORTON 66254433506 is an aluminum oxide unitized deburring wheel designed for light material removal, edge blending, and surface finishing on metal workpieces. At 3 inches in diameter with a 0.25-inch face width and a 0.375-inch center hole, this wheel mounts directly to die grinders, inline grinders, straight grinders, flexible shaft grinders, and pencil grinders. The medium-grade, density-5 abrasive construction delivers consistent cut rate and finish in a single-pass operation. Machinists, fabricators, and tool-and-die technicians rely on unitized wheels like this one to deburr bored holes, chamfer edges, and blend weld seams without loading or glazing.

This wheel is suited for shop and production floor use where hand-held rotary tools are the preferred method for finishing inside diameters, contoured surfaces, and drilled or punched edges. It is well-matched for ferrous and non-ferrous metals in both light manufacturing and maintenance-repair-operations environments. The compact 3-inch diameter fits into confined areas that larger bench-grinder wheels cannot reach, making it practical for deburring tubing, pipe ends, castings, and stamped parts.

Key Features

• Aluminum oxide abrasive — durable cutting action on steel, stainless, aluminum, and non-ferrous alloys
• Density 5, medium grade — balanced cut rate and surface finish for general deburring and edge blending
• Unitized wheel construction — abrasive is distributed throughout the wheel body for consistent performance as the wheel wears
• 3-inch diameter with 0.375-inch arbor hole — fits standard die grinder mandrels
• 0.25-inch face width — precise contact for narrow edges, bores, and contoured features
• Compatible with multiple rotary tool types including die grinders, pencil grinders, and flexible shaft grinders

Compatibility

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

Installation Notes

This wheel is installed by a machinist or metalworker onto a compatible grinder mandrel rated for the wheel diameter. Verify that the grinder spindle speed does not exceed the maximum RPM rating marked on the wheel before mounting. Ensure the arbor nut is secure and the wheel is properly seated on the mandrel before operating. Always wear appropriate eye protection and follow applicable shop safety and ANSI B7 grinding wheel standards during use.
