Thread Chasers

Handled Thread Chasers (as shown) can be used to repair damaged external or internal threads by holding them against a threaded bar as it slowly rotates in a Lathe.

They can also be used in this way to cut threads in wood (e.g. for projects such as box lids). The external Thread Chaser has its cutting teeth on the end of the blade and internal Thread Chaser have cutting teeth on one side face. They are available for standard TPI.
