Does anyone know for sure what the drill chuck taper is on a 6” Craftsman drill press?

I get a lot of run out and would like to upgrade the chuck, but I don’t the exact taper the press takes.

Any help here is greatly appreciated!

Can you take the chuck off and take it with you to get a new one?

Being this small, it is likely to be threaded with a 3/8 fine thread. Put a 3/8 allen wrench in the chuck and HIT it hard to the left. It will either unscrew or if it is tapered, it will come off. Either way you will have a sample to renew with.

And he should probably mention that you hit the wrench… not the chuck… since that wont do what you want… lol…

6” drill press? Mind my asking what its capable of? It sounds it like something used to bore the wheel holes, for HotWheels cars….

I had a similar problem with a drill press I restored earlier this year. I needed a replacement chuck and wanted to make sure I purchased the right one.

Here is technical info on the taper dimensions top and bottom. Use calipers to measure the top and bottom diameters and you can narrow down (pun intended) the choice of taper. Mine and, from what I’ve read most drill presses, had a JT33 taper.

Thanks for everyone’s input.
I guess the drill press is 12” not 6”. It is the common bench top style with a 1/2” drill chuck.
I like it, but the chuck has too much runout. You can see and feel the drills wobble.
Thinking I’ll just take the advice to remove it and take it in for a possible match.

Just thought someone would know right off what the taper for Craftsman’s were.

Appreciate it all!
