ot drill+point hole and thread together

[reggio]

hi to all and apologize if I am ot, it is a bit of time that I am rethinking to a tool that I had seen qlc year ago and I do not remember what it is called and especially who produced it.. .

in practice it treated a drill or a special tip that while forging it created (by hot deformation) also a "inspection" that was then used to be threaded... the result was something similar to the annex.

I would now need to drill and fill tubular with low thickness and we want to avoid internal bushings or various rivets... .

Can you tell me his name and who produces it?

thanks to all; for the record and to finish the speech, I turn you qlc price: we hang around 350/400euro... (February/2010)

about 180euro between point & point port, the rest is the cost of each single tip ø8 ø10 ....

there are tips that create the upper edging and others that instead "cut" it away and leave a top floor.

it is mounted on high speed drills 3/5000 rpm and with discreet powers (it does not work on the hobbies column drill to understand).
