Those are great drill presses. That one looks well cared for. They were made for Sears by Walker Turner, a well respected industrial manufacturer.
They have a wide following here on GJ and elsewhere. Check the thread dedicated to the use and repair of those classic machines. Frank Lee is your authority.......
Thanks for the advice so far. It doesn't appear to have the third pulley. Any idea what the slowest speed is without it?
WOW ! Prices must be expensive there. Floor standing decent drill presses are usually around $100.00 to $150 depending by me.
I suggest IF you are going to be drilling metal, get a two belt setup. Slower speeds are best for metal and using holesaws. Some expensive one do have lower speeds if you can find you.
Check Craigslist and facebook marketplace.


Are you sure about that? Many of the same model drill press say "King-Seeley" right on the label.
$250 would be a high price in the Chicago area unless it had the optional third pulley for slower speeds. And ideally they would be the 150 version with the quick-change depth rod and the tilting motor mount.
A similar DP as the OP's (not a 150) but has the third pulley has been on CL for awhile now at $200:

That's too much for that unit. If you intend to drill metal, you're going to put another $150 into it. Just look for a three pulley unit.
Unfortunately all the thee pulley units I’m seeing in my area (Los Angeles) start around $400 and are pretty beat up at that price point. If I do spend $150 for the third pulley I’ll be all in at $375...not a steal by any means but pretty reasonable I think for my area for the unit I’m getting.
Thanks all for your thoughts. Prices seem to be inflated in my area...the seller and I have agreed on $225 and I'm going to go check it out (and hopefully bring it home) on Thursday. Any tips on things to check while I'm there?
I do plan on drilling metal at least occasionally so I'll need to find a way to slow it down. I'm sure there are a couple threads here to help with that.![]()
I am always a fan of spending a little more and not getting a big project. Small projects are fine. This is after many years of restoring machines!
Per the Craftsman 100 docs I have, the lowest speed is 625rpm with a 1725rpm motor.
A few options to slow it down more.
1) Buy a 1140 rpm single phase motor. Lowest speed drops to ~417 rpm. I see them for $53 shipped on Ebay. Remember that a 1/3 HP 1140 motor has about the same torque as a 1/2"HP 1725 motor.

2) Make it variable speed using a knob or keypad. Buy a 1140rpm 1/2HP 3 phase motor off of Ebay for $63 shipped and add a 120VAC Variable Frequency Drive. I would avoid the cheap Chinese Huanyang VFDs as they have had so many issues the electrical forum on Practical machinist will not allow discussion of them.

3) I personally like to use industrial (Baldor, Leeson, Reliance, Pacific Scientific for example) 90VDC motors + variable speed DC drives that run off of 120VAC wall power for this application. The motors tend to cost more but the used drives cost less on Ebay. My hearing is quite good and the DC drives do not have the whine of the VFD chopper output drives. Photos below are the Leeson 1/2HP motor with Minaric NEMA 1 enclosed drive I need to bolt back on my model 100 drill press.

4) Or build your own step down pulley speed reducer and use the standard motor. I like the Cardinal Machine long discontinued #18 slo-drive design as a starting point (see below). I would use just one belt not two for the first reduction since it is only 1/2 HP. Not too hard to make using pillow blocks, ground rod, spacers and pulleys.
