Topic tags/keywords: jet jdp-15mf jet drill press

I could write a review, but I won’t. Let’s just say that I am generally unhappy with this drill press and I lack the permission to get something better.

That being said, the chuck has to go. It is a total piece of crap. No matter how hard you tighten it, the thing will not hold a bit secure. I have had numerous instances of a bit slipping, which is very frustrating.

Does anyone have a suggestion for a replacement chuck? Jet JDP-15MF 3/4hp.

Jacobs chucks are the standard of excellence as far as I know, but there are some pretty good clones available.
Just be sure to get the correct taper.

Last year I purchased a beast of a drill & mill at auction the chuck was a old Jacobs that had seen a pipe wrench a few too many times. I purchased a 3/4” made in china on ebay for around $25 (don’t recall the exact price but that is close). It came with a #2 morse and a R-8 taper. I am very pleased holds well and runs true. It will not grip drills 1/8” or smaller but I expect that is because it is a really big chuck. I have a 3/8 chuck also made in china that I use for small drills.

Chucks do have a minimum drill size. Use a micro chuck in the big chuck and put the small drills in the mico chuck. I have a 5/8 Tiawan chuck on my press and it stops holdin when you get smaller than 1/8. this was my cure.

Chucks have a life. A machinist once told me that they would change every chuck in the shop, once a year.

Are there other issues with the tool that could be addressed? A drill press is a pretty simple piece of machinery, and generally not a source of frustration. I bet the collective wisdom of LJ could help you turn it into a sweetheart tool, with very little expenditure.

Lee, other than the cheapest key money could buy, which really ircks me, the chuck is my main source of frustration. I probably only have 4 – 5 hours of run time on it since I purchased the drill new that past summer.

And it doesn’t seem to be dependent on shank diameter. I’ve had bits spin from 1/8” up to 1/2” in the middle of a hole. Not always, but my dad’s old Craftsman never did this.

I’m just really annoyed to the point of purchasing an aftermarket chuck. Thoughts?

You may have just gotten a lemon chuck. Contact Jet and see if they’ll send you a new one. Their 15” press is a good one.
