External Deburring Chamfer Tool for Bolts and Fasteners Key Benefits Removes burrs efficiently by using the lowest drill speed and applying light pressure. External chamfer works by shearing metal layer by layer for a smooth edge. Safety conscious design minimizes the risk of hand cuts during use. for repairing damaged bolts and fasteners, restoring usability. How it works Attach to a drill, set to the lowest speed, and apply light pressure to begin burr removal. The tool gradually shears burrs and forms a clean external chamfer. Material and maintenance Construction: hard steel. Lubrication: lubricating oil can be used to improve tool performance when working with hard steel. Safety and usage Follow standard drill safety practices. Secure the workpiece to prevent movement and keep hands clear of the rotating area. Applications Repairing damaged bolts and fasteners in automotive, machinery, and hardware projects. Deburring and chamfering external ends of bolts and fasteners during assembly or maintenance. Finishing newly machined external surfaces on metal parts to remove sharp edge burrs.
