    For some reason many big drill presses run 1175 RPM. Brian & I both have big Williams? drill press/Tappers that run about that speed. I just thought for $49 if anyone is close & don't have to pay shipping it's good yo have a couple around & a good price.

      Not as many as you can, you have a vast market of choices. But you know that as well as everything else.

        Same thinking here.

          -I wish I'd been able to find one back when I had a nice Rockwell vari-drive drill press. It was a great drill, but even at the slowest speeds, much too fast for bigger drills- it would have been fine for a woodworker, but even in aluminum, it was too fast for anything over about 3/8".

          I'd tried to find an inexpensive 1175 motor, but could only find one online- in which case shipping to Alaska was just too damn expensive.

          I eventually found an Arboga gearhead, and subsequently sold the Rockwell to a woodworker. Slowest speed on the Arboga is something like 80, and with the VFD, I can of course slow it down from there.

          Doc's Machine. (Probably not what you expect.)

            Doc, I have 12 new ones, a different brand & heavier 115# each.And if you really want to drill a 100 HP new motor but it's 3450 rpm. I got an Arboga radial drill in the 32 machine buy that was deleted, nice as it's 220 3 phase, has a large table so no tombstone needed. Also am Arboga dedicated tapper the size of a floor model drill press. I also have a PRATT & WHITNEY SIGOURNEY sensitive 3 head heavy as H*LL like this only 3 head I use mainly for gun work.
