I have an extra gundrill for sale. It's .750 x 6.75" of bore depth. The shank is .850" dia. and has a 9/16 x 18tpi threaded end. This works great for boring ring billets, stepped forearms, etc. Price is $30 shipped to the 50 states. SOLD If you need a threaded adaptor to hold it in a 1/2" drill chuck, I can make one for $20 extra but you will have to drill it for air fittings once you get it. I included a picture of the one I made for my drill.
Thanks,
Dave

For anyone interested, I made one out of a bit just like this for my taig lathe, I turned down the threads and made a collar out of brass and threaded the flat part in front of the threads for the air fitting. I put a pin in the brass where the threads were on the bit, and it has worked great. I can post a pic in if anyone is interested.
 
I told a couple people I would post pics of how I made a couple of these bits work for my taig. I cut pieces off an old brass punch, that's why it looks a little rough. I made these pieces on my large bore headstock. With the threaded air fitting I don't have to worry about epoxy.
