Norton 66254433503 Deburring Wheel 3 Inch Aluminum Oxide

Product Description

The NORTON 66254433503 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 Density 5 construction, it delivers consistent cut and controlled flexibility across the wheel face. The 3-inch diameter and 1/8-inch face width make it well suited for detail work in tight areas. This wheel is installed on die grinders, inline grinders, straight grinders, flexible shaft grinders, and pencil grinders, and is commonly used by machinists, fabricators, and maintenance technicians in production and job shop environments.

This deburring wheel fits standard small-tool grinder applications where controlled abrasive action is needed without aggressive stock removal. It is appropriate for deburring drilled holes, easing sharp edges, and blending weld seams on ferrous and non-ferrous metals. The 3/8-inch center hole matches common mandrel sizes found on die grinders and similar rotary tooling. Density 5 provides a medium-firm structure that holds up during repeated passes while conforming slightly to contoured surfaces.

Key Features

• Aluminum oxide abrasive provides reliable cutting action on steel, stainless, aluminum, and similar metals
• Medium grade and Density 5 structure balance cut rate with surface finish quality
• Unitized wheel construction bonds abrasive throughout the wheel body for consistent performance as the wheel wears
• 3-inch diameter with 1/8-inch face width targets detail deburring and edge work in confined areas
• 3/8-inch center hole fits standard mandrels for die grinders, pencil grinders, straight grinders, inline grinders, and flexible shaft grinders
• Lightweight at approximately 0.03 pounds, reducing operator fatigue during extended use

Compatibility

Designed for use with die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders. Requires a compatible arbor or mandrel with a 3/8-inch shank to seat the wheel properly.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and disconnect the grinder from its air supply or electrical source before mounting or removing the wheel. Verify that the grinder spindle speed rating meets or exceeds the wheel's rated maximum RPM before operation. Inspect the wheel for cracks or damage before each use and do not use a damaged wheel.
