Chuck for drill press

I have an old Montgomery Ward table dill press that Needs a chuck. I don’t know much about it except it is a 1/2” and presses on a tapered shaft. If anyone knows where I might find one I’ll try to post more info. I’m guessing it was made in the 1950’s.

There are two measurements regarding drill press chucks, a Morse taper fits in the hole in the drill press, it is just a matter of measuring the width of the opening and comparing it to the attached chart to determine the Morse taper size.

There is a second tapered hole in the chuck, this is a Jacobs taper and can be determined by comparing the measurement to the chart as well.

Replacement chucks are sold separately or with an arbor, if you still have the arbor in your drill press then you just need to find a chuck with a Jacobs taper to fit. If there is no arbor then you need both with a Morse taper to fit.

Any brand of chuck will work as long as it has the proper tapers to fit, best deals are on Ebay but they are available at most tool stores if you are in a hurry.

Do you still have the old chuck? The taper will be stamped on it. Do you have the model number of the drill press? There are sites with info on antique machinery that sometimes have the manuals. I found the one for my 5Os Sears jointer. A manual would most likely have the taper info. A little research and you may learn who made your press. See where it goes unless you can get accurate enough measurements of the taper to buy with confidence.

If the specs on your drill press match this one from Einstein, I can highly recommend this replacement chuck and arbor, https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 .

Just guessing, JT33 is a pretty common 1/2" drill chuck taper.

Just checked and the chuck has; Jacobs Multi Craft Chuck, MC33R33, 5/64-1/2 in. capacity. Would this be the same as the JT33? Also the model # on the press is TRT-2577.

It would appear that it is a common JT33, just make sure you can return the chuck if it doesn't fit.

Just did some research on the old gal and it seems it was made by Delta Manufacturing Co. around 1946. It is called a 32 in. Radial drill press. The motor has been changed and works great. The chuck key doesn't fit tight which makes it hard to tighten a bit.

Maybe a new chuck key will solve your problem, cheaper than a new chuck.

Secret to most chucks with three holes is to go around and tighten each of them.

There seems to be a large number of keys out there. I haven't been able to find one that fits. I use the three hole method and it helps but I would like to get it working correctly.

besides the taper fit, you also need to consider the jaw capacity - minimum that is. there are many chucks that can't tighten to 1/16" or less making it difficult for small bits. Jacobs 14n.

As I stated earlier my current chuck capacity is 5/64-1/2” and that works for me. There is nothing wrong with my arbor( at least I don’t think there is ) so I think all I need is a new chuck w/ key. I may try the Einstein, I’ve waisted $28 before.
