Pilot Nose Wire Insert Taps

 
  Our Pilot Nose taps have been developed for the repair of damaged sparking plug threads without the need for additional drilling.

This type of tap uses the original thread to guide the tap. It has reamer faces behind the pilot thread which cut the hole to size prior to tapping of the wire insert thread form.

They are simple and easy to use and in 1 single operation ensure that the wire insert thread is concentrically aligned to the original thread.
