Pilot Nose Tap Information.

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.

Tap creates an oversized thread for use  with standard Helically wound wire inserts.
