I am looking to buy a cole drill for a job. Does anyone have one they would sell? Is this type of drill being made anywhere? Has anyone made one?
Thanks, Paul L

I think they are used in hard to get at places where you can't put any pressure on the bit due to location. Used on ships and boiler rooms and things like that.Originally posted by Carld- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.
It is true, there is nothing free about freedom, don't be so quick to give it away.Comment

They are a wonderful little device that do allow portable drilling in otherwise difficult locations. But they also allow drilling of materials that you really can't even power drill. For instance, you can drill through very hard materials using common bits because of the enormous pressure generated. And you don't even break a sweat doing it. It'll sink a 1" drill through a piece of truck frame in under 30 seconds with no effort to speak of. However, it is a bit bulky, so in some cases, difficult to get into position for the work.Russ

Hmm, seen them before but didn't know they are Cole drills.It's only ink and paperComment

So I've heard that they can drill hardened steels etc, can anyone explain how this is possible? I mean I can put alot of pressure on a drill in a press and all it will do is dull the bit against hardened steels.Comment

I have one but it's not for sale. If you're close, you can borrow it! I've used it three times this year and would have been lost without it. The only other option would have been drilling the holes with a cutting torch. Stuff that's too large for a drill press or mill or too remote for electric are ideal candidates for the Cole drill.Comment

PM sent I have one to sell KenComment

Cole Drill
I have one. Would not part with it for any amount of money. It will drill anything that won't break the drill outright. Glass, Granite, Hardened steel, Grey Cast Iron - right through a weld, all have succumbed to my Cole drill at one time or another. Even drilled a half inch hole through a grinding wheel. Why? To take $50 off a loudmouth willing to bet me I could not do it.Comment

So if I understand it. The bit is held rigidly in the spindle and as the handle is turned there is a thread on the spindle that forces the bit downwards?
Like a tap stand with a thread added to the spindle instead the of tap spindle free spinning.
If that's how it works... what's the TPI of the thread? Would seem to be fairly fine otherwise you'd be taking a hell of a bite, but also needs to take a lot of force. hmmmComment

There is a rathchet on the downfeed nut so you can dial it in a butthair or hog it in.Comment

It looks like you have to use a big wrench on the downfeed nut? And the spindle slips through the nut. So you tighten the nut, crank the handle, tighten the nut.. etc... ?
I found a brochure here showing some uses for it and it says that it can put 1000lbs of force using a 10tpi thread. But doesn't go in to the operation.
