Thread repair tools automatically adjust to any thread diameter and pitch, can be used on left hand or right hand threads, both inch and metric and need no prior measurement of the thread. Often the thread of a component is damaged at the end of the thread eliminating the use of taps or dies for carrying out the repair. These thread restorers have the capability to enter below the damaged area and work outwards to complete the repair. The blades are made of high quality hardened tool steel. The blades are guided by the existing undamaged section of thread, in order to regroove the damaged section. External Tools
