Norton 66254433507 Unitized Deburring Wheel 3 in Aluminum Oxide

Product Description

The NORTON 66254433507 is a unitized deburring wheel designed for light-to-medium material removal on metal workpieces. Built with aluminum oxide abrasive at a medium grade and density 9 construction, it delivers consistent cutting action while conforming to contoured surfaces. The 3 inch diameter and 0.5 inch face width make it well-suited for precision deburring, blending, and surface conditioning tasks on smaller workpieces and tight geometries. At 0.1485 pounds, it is lightweight and easy to control during extended use. This wheel is installed and used by machinists, fabricators, and maintenance technicians working with die grinders and inline grinders in production or shop environments.

This unitized wheel is intended for use on ferrous and non-ferrous metals where edge deburring, weld blending, or surface prep is required. The 0.25 inch center hole size fits standard mandrel tooling used with die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders. It is well-matched to bench work, hand finishing on fabricated parts, and finishing passes on machined components where a consistent, repeatable cut is needed without aggressive stock removal.

Key Features

• Aluminum oxide abrasive at medium grade for controlled deburring and surface blending
• Density 9 unitized construction maintains wheel integrity and delivers even abrasive exposure
• 3 inch diameter with 0.5 inch face width fits compact tooling and confined work areas
• 0.25 inch center hole mounts directly to standard mandrels for die grinders and inline grinders
• Compatible with die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders
• Lightweight at 0.1485 pounds for reduced operator fatigue during detail work

Compatibility

Designed for use with die grinders, flexible shaft grinders, inline grinders, pencil grinders, and straight grinders equipped with a standard mandrel accepting a 0.25 inch center hole arbor.

Installation Notes

Mounting this wheel requires a mandrel matched to the 0.25 inch center hole — confirm mandrel fit before operation and tighten securely per the grinder and mandrel manufacturer instructions. Disconnect power from pneumatic or electric grinders before mounting or removing the wheel. Always confirm the grinder RPM rating meets or exceeds the wheel speed rating before use. Wear appropriate eye and face protection during all grinding and deburring operations.
