Default Jet JDP-20EVS/230 Drill Press

In the parts I make for the boiler company, the size of the material, 3/8" - 1", requires lots of drilled and tapped holes, tapping a large number of 3/8"-16 to 1"-8 threads in thick plate is not fun. I ended up buying a Jet JDP-20EVS/230 drill press with a built in tapping head, a 20" industrial DP with a built in flood coolant system, an electronic variable speed controlled 2hp, 3 phase motor connected to a two speed gear box, giving ranges of speeds from 65-2000rpm, it uses a inverter type VFD and has 230 volt single phase input. After set the tap depth, tapping the plate is very smooth and easy, tapping is no longer a chore, I don't use it on taps smaller than 3/8, and only use either spiral point or machine taps. A massive 700#+ machine with a 22" x 19" table and a superior table locking system. A great machine, smooth, solid, and has a MT #3 taper and came with a very high quality 1"chuck. The bad part was the cost, about $3500.

That looks like one heckuva nice machine, Jack.
How small will that chuck grip? Looks like a Jacobs 20N?

Looks like a very nice press Jack. I have an Ellis 9500 that I use exclusively for tapping. If I had to do it over again, I would go with this one as it is around the Same money as your Jet. Ellis is a great company and good guys to deal with.

BTW, what brand of DP vise is that on the table?

Cutter,

Its a privately branded Japanese chuck, made for Jet, all ball bearing, its 3/16" to 1" capacity, very well made.



KB,

Yes, the Ellis is a nice looking piece, if at the time, it has been an option, I might have gotten that instead of the Jet. The DP and the Jet mill, were a package deal, the package price was real good, as the rep needed to sell $4000 more Jet products to get his product discount for the next year, so I got them for cost plus 10%. The DP vise is a 8" Palmgren, its mounted on the drill press adapter plate I made, with this DP, you want the piece to be rigidly gripped.

Jack

Very nice machines Jack. Is that the same drill vise mounting plate that was featured on here?
I agree that, when drilling those big holes, you don't want to just hold the piece with your hand.

On my tiny, 1937 Companion drill press, I just swing the vise around, so that it touches the column and won't spin. I also have the belt set to slip, if the bit hangs up. For heavy stuff, I use my mill/drill. That works pretty good, as it's more drill than mill.

Wow Jack, are you saying Christmas came early, or late?

I've read good things about the mill and find it more than adequate price wise for it's size and capacity.

Sounds like the price was right as well.

Dave,

Yes, that the plate that I did the thread on, making it possible to have 4 bolts holding the vise to the plate and 4 bolts holding the plate to the DP table. I run 3 drill presses, the big Jet, JDP-20EVS/230, for tapping, and large holes, another Jet, JDP-20MF, with a keyless chuck, for anything from 5/16" and below, and a 20" HF floor model DP, for everything in between. Here pictures of the different plates for each. The plates for the 2 smaller drill presses, are dilled for multiple different vises, both use a 6" Palmgren, but can also use a 6" ShopFox with jaws for round objects, and for a 4" Craftsman angle vise (a relabeled Palmgren).

1 - 8" Palmgren on a Jet model JDP-20EVS/230
2 - 6" Palmgren on a Jet model JDP-20MF
3 - 6" Palmgren on a 20" HF Drill Press

Nice set-up Platy, Much better than fiddling with C-clamps.
