I started looking at the Taig micro mill, planning out what parts I will need, etc. One of them probably being a drill chuck.

The option I found first was using the Taig accessories:
- (Taig 1091) 0-1/4" Jacobs drill chuck, commercial quality 3/8-24 thd.
- (Taig 1140) Drill chuck arbor (3/8-24 thread), attaches Jacobs chucks to headstock spindle. (3/8" straight shank).

Then I found these at LittleMachineShop:
- Arbor, Drill Chuck 3/8" Straight to 2JT
- Drill Chuck, 3/8", 2JT

Which (if it works), seems better than the taig option.


There are also some fancier chucks on LMS, but they are all 33JT. And the smallest straight shank to 33JT adapter I could find is 1/2" (here). Is it unreasonable to use such a large chuck on a small machine?

Are there any other options people have found?


Thank you

If you got a lathe, just make your own adapter for a drill chuck. Thats what I did for my Sherline mill, my cost $2 for a flea market chuck and didn't cost me anything to make the adapter. Of course I work nites at a tool and die shop so I was lucky and they had the right die for the thread I needed. But I could have threaded it on the lathe if I had to.

Here is another option:

I use this adapter to screw directly to the E-16 thread and then screw in the 3/8 x 24 Jacobs chuck. I have the 1/4", 3/8", and 1/2" chucks. They all work fine this way. (though the 1/2" chuck looks a little big)

I'm using a 0 to 1/8 keyless chuck on a 3/8 straight shank on my ER16 Taig. This works well and runs true.
