I would say 50s, maybe 60s. Dad bought one in the early to mid 70s and it looks like what lilredex depicted.It looks like a 1/2 inch, if so it strongly resembles an older model that I have. Mine is known to be WW 2 era, yours is newer. The handle on the rear and the I.D. plate remind me of drills similar to mine from the 50's or 60's. That's about all I can provide from memory. The model # might be 1320-90. There should be a hole in the top with pipe threads for an additional handle. If you can read the serial number, it might reveal some more information from one of the vintage machinery sites. They were slow speed, high powered drills that were incredibly durable. Yours looks like it's been exposed to moisture and might need to be cleaned up but, if it's rehab-able should be a valuable addition to your tool crib.

I have the same drill; with the addition of a 1/2" red pipe handle on top.
The chuck is Jacobs attached with 33taper.
It has slow rpm but will break you arm with torque...
Chuck slippage as a feature, kinda like how my skil 77 slips when the blade is mounted correctly : )I have a Craftsman drill of that design. Boy was one of the posters accurate they have extreme torque. I was drilling out a floor from the basement with a 2" hole drill with a extension that had a hex end for the chuck. It hung up and about broke my arm. I learned that that hex end needs to be cut off so that the chuck can slip on the round shaft. Mine didn't have the pipe thread for a top handle it had like a 3/8 thread plastic handle up there that went by-by when that happened.
Part of the learning curve of using a 1/2 drill. I don't use anything over 3/8.As said earlier, the torque on those old drills is amazing. I have heard stories of guys getting thrown off ladders when the bit bound up. Serious injuries from that. Be careful if you get that old guy operational and decide to use it.![]()
Matter of fact, I've been thrown off a ladder by a Hole Hawg running a 4" hole saw. Fortunately, I was only about twenty feet off the ground and landed in the landscape shrubs. The Hole Hawg kept running until it wound the cord up enough to unplug itself (if you use an old Hole Hawg left-handed, which I was doing, it automatically locks itself on).As said earlier, the torque on those old drills is amazing.

OUCH !!!!Fortunately, I was only about twenty feet off the ground and landed in the landscape shrubs.
I was on scaffolding on a commercial job drilling a 1/2 hole through the web of a structural steel W-beam. Needed a mag drill, but didn’t have access to one. Corded hole hawg it was. I was drilling at head height and when it finally punched through, the bit caught and I was KO’d by the drill. It might have broke my jaw, I never got it checked. Almost came off that scaffolding!Matter of fact, I've been thrown off a ladder by a Hole Hawg running a 4" hole saw.

The shrubbery suffered more damage than I. Of course, I had to do my best to fix it.OUCH !!!!

I used a similar drill, provided by the homeowner, to bore 1/2" anchor holes through railroad ties that I was using to build a retaining wall. Every time I'd bore through the ties and the auger touched the ground it would trip the GFIC, which was a breaker in the box on the opposite side of the house. It slowed things down some.Drill like in the OP's picture shocked the hell out of me when I was 16. Havent trusted any old metal case power tool since. I know what I'd do with the one pictured if it was in my shop....![]()
Yep. If using it to drill into wet wood or beams with an auger bit, definitely need to use the pipe. The way the rear handle is, if the bit catches, it twists your wrist so quickly, you're in for a jolt. The pipe handle allows you to give some resistance to twist if that happens.As said earlier, the torque on those old drills is amazing.

I've used one of those drills to turn over small tractors.

Offer to safely dispose of them.I recently found a bunch of'60's through 90's era power tools at work. Some of them still work, but they have cracked housings, broken buttons, or frayed power cables, and are thus not allowed to be used.
Bummer.
Far away from the site!Offer to safely dispose of them.
Check to see if OSHA had banned them from worksites. That will give you leverage.I have a standing offer. LOL. They are mostly Old Craftsman, Black and Decker (back when they were an industrial brand), DeWalt, and a few others. Some with metal housings. Unfortunately, the inventory control specialist is...difficult to work with at times.
If they have worn, cracked cords or missing ground pins, yes, they have.Check to see if OSHA had banned them from worksites. That will give you leverage.
