I originally posted this in the metal working newsgroup, some folks there
thought the part might be recobnized by somone here - so, it's worth a try -
any clues?

thanks:



I think this is probably quite old, but so far I have no idea what it is (or
was part of) - there is another like it that has been sharpened to use as a
boring bar - clearly that was not its original purpose. the one pictured in
the drop box appears to be original - but orignal what, is the question.

here are the links to the drop box:

Anyone got any clues about this item?

The text file from the drop box is reproduced below:

Mystery Pratt & Whitney tool - the cylindrical shank is exactly .500 inches,
it says on the

shank, the following:

NO. 32
HS.-36
E-12

P&W
MFD CT
Made in USA

it is NOT a drill bit. The part that extends beyond the 1/2 inch diameter
shows a wear line

like it was riding in a keyway. The point seems to be lathe turned, the 1/2
inch shank

appears to be ground

first guess was a spot facing borer
but the wearline contraindicates that.
maybe a machinable dead centre for some special tooling jig.
