If you've had to drill out a sheared shaft these are useful to clear the remnants from the hole. If the thread is damaged you can sometimes shave off the damage to restore it, otherwise, drill it larger, tap a new thread and use a large shaft for the repair (if the assembly will allow it).

Use to...

  • Repair damaged internal threads.
  • Clean dirty internal threads.
  • Cut new internal threads.

Buying Tips

  • Buy a T-handle if not included.
  • Available as a kit with a matched drill bit.
  • Consider a full tap, die and drill set.
