High-quality materials: The deburring tool is made of high-strength high-speed steel, which is hard and abrasion-resistant, to ensure a long service life and consistently effective chamfering results. Features: This deburring tool is specially designed to repair damaged bolts and fasteners. It can easily deburr the rough edges of pipe cutting bolts. Using a lubricant will greatly improve its efficiency, and the polished bolt will be smoother and more complete. Versatile: The metal deburrer can be effectively used on stainless steel, threaded rods, copper, brass, aluminum, plastic and wood. Efficient chamfering: The carbide blades are sharp enough to quickly and accurately remove burrs from the surface of the workpiece, resulting in smoother edges and precise chamfering. Easy to use: The deburrer cuts the metal layer by layer. It does not cut your hands when using it, and does not produce sparks or burns. It can quickly repair damaged bolts and tighten nuts in place.
