Engineers / Thread Chasers

Chasers are available to chase threaded parts having standard threads. The internal thread chaser has its cutting teeth located on a side face. The external thread chaser has its cutting teeth on the end of the shaft. The handle end of the tool shaft tapers to a point.

Thread chasers are used to rethread damaged external or internal threads.

Chasers are  available  to  chase  threaded  parts  having  standard  threads.    The  internal  thread  chaser  has  its  cutting  teeth located on a side face.  The external thread chaser has its cutting teeth on the end of the shaft. The handle end of the tool shaft tapers to a point.

Select the proper thread chaser for the job.  You must know the number of threads per inch on the work. If screw pitch gauges are available, use them to determine the number of threads per inch.  

Care  of  Thread  Chasers.    Never  attempt  to  sharpen  thread  chasers  yourself.    This  is  a  highly  specialised cutting process which involves precision work on hard tool steel of a shape altogether not suited for simple stroking on an oilstone.    Store  chasers  carefully  when  not  in  use.    Coat  with  a  light  film  of  oil  and  store  individually  so  that  the  cutting edges do not touch other metal.  For long periods of storage, coat chasers with a rust-preventive compound and store in a dry place.
