Internal Reverse Threading Insert

[ashisroy]

I'm trying to do reverse threading in internal blind hole. My target is to easy chip evacuation as the holder will pull the chips while reverse threading from head stock towards tail stock. My question is, is it possible to use an external RH lay down threading insert in a reverse threading LH holder for internal RH threading? I've the attached holder. Please advice.

You could use a normal right hand external threading insert in this holder, that if it fits. But yes with a left hand tool if you start from the inside and cut towards the outside of an internal thread it will give you a right hand thread.

Use M04 for RH internal threads, if machining left-to-right.
The tool holder should be held in the proper orientation so that it cuts on M04.
