Tie rod reamer

[GPster]

I don't suppose what I have can be refered to as a reamer. Like I said it is a tool for a mill and rather than having straight blade in a line it's blade have a curve to them almost like it would screw itself into the work. The taper seems to be correct and it is a cut-and-try and cut some more if need be proceedure. It keeps me out of trouble but I wouldn't use it comercially. GPster
