what piece of machinery does this fit?
Hello again, first off I know what it is, what I don't know is what it goes to. It's a 90 degree 1 to 2 drive, the only thing I can find is: on the inside it says " made in USA" the input shaft is a 5/16"x24 thread( I put the nut on) , the hole for the brace(?) is 5/16"x18 thread. It has a 1/4" Jacobs chuck (usa) . Hell, I don't even know where I got it. Any ideas?

It's a 90* drill adapter chuck. Chuck the threaded end/nut in any drill that is large enough to hold it & your bit in the chuck & then drill. I have a similar one somewhere around here that I don't use cause I have several 90* drills. I am not sure what the threaded hole in the webbing on yours is for. Maybe for some kind of handle?

Re: what piece of machinery does this fit?
I think due to the threaded shaft it is some sort of machine part. I dunno

It's a 90 degree adaptor for an electric drill.
I think the input shaft thread size is specific for a particular brand of drill. Black and decker used 3/8 UNF. There might be a drill that used 5/16 UNF. The threaded hole would be for a handle. You would need a handle to steady it in use. |

Re: what piece of machinery does this fit?
Those old drills were monster sized compared to today. A 90 could save you a lot of grief in tight spots.

Re: what piece of machinery does this fit?
I agree with "Mart". Years ago, a friend of mine had one that looked a lot like that (I don't remember the threaded hole, though). He found it completely useless; it was almost impossible to control.

Re: what piece of machinery does this fit?
Yeah what throws me is the input shaft is threaded like it's supposed to thread into maybe like the old shopman?

Re: what piece of machinery does this fit?
There are several similar ones on eBay right now. This one has the threaded input shaft like yours. The other ones listed have the smooth shank. The handle attaches as shown in the listing. Looks like a beast and heavy duty. Built to last.

Re: what piece of machinery does this fit?
I had one similar, but smaller, many years ago. It had a smooth shank and fit into a 1/4 or 3/8 drill. It had a buffing wheel on it when I got it. You could hold the head in the palm of your hand. It was good for getting into tight places if you did not want to remove a part from the car. I could see that with all the different discs available now it might be handier than 50 years ago.

Re: what piece of machinery does this fit?
Some industrial stuff was flex shaft driven back in the day. The motor would be hanging around near the job at hand with a flex shaft much like a speedometer cable to drive different appliances that would connect to it. Foredom took this stuff to a science. They make some damn good die grinding type equipment.
The one in question may just be a 90 degree drill adapter but all I can observe is that it is oddly shaped and somewhat large compared to some I've seen. The bolt hole looks to have been to mount it to something unless it was for some sort of handle. The chuck looks to be a normal size Jacobs type. |

Re: what piece of machinery does this fit?
The OP's 90° adapter, is for use on a drill motor. The stud would be removed and screwed on to the drill motor, after the drill motor chuck is removed.
The threaded hole, as Mart says, is for a handle, to put pressure on and control the drill. I'm not sure if the stud would have been part of the original adapter or it could be a spare to mount another chuck, of a larger or smaller size, in place of the mounted chuck.

Re: what piece of machinery does this fit?
I have the exact same 90 degree tool without the
threaded adapter. Remove the chuck from the drill motor and install the 90 degree tool then screw the chuck onto the other end. Never had a handle ,but cut alot of 3" holes in my soffit for vents. |

Re: what piece of machinery does this fit?
I have an old Craftsman one that’s similar. Mine will hook up to the drill on either end so you can run half speed or twice the speed of your drill. I really have only used it for drilling floor joists and studs for running plumbing and wiring.......Mark

Re: what piece of machinery does this fit?
I also have an old one that I use in places that you just can't get to with a straight drill, like between studs. When you need it, you will be glad you have it.
