Saw this on ebay (Aus) under antique blacksmith tools. Does anyone know what it was used for??? Had stated that it was ex military.

Some kind of pipe threading type machine?

I used to have one of these & been told by someone who used to use one that it's for working on water mains. Can't remember exactly how it's used but he seemed pretty sure.

Looks like some sort of reamer.

Internal wrench? Does it have a brand name on it? I was thinking reamer at first as well, but for some reason I think internal wrench. It would fit inside in inverted cap on a pressured line perhaps or drainage.

Hi guys
Its a hand drill wrench, the photo actually has it upside down. The pointed bit goes against a stong arm arrangement that you clamp or attach to whatever you want to drill or you can even use a chain going right around say a boiler or such with a plate so as the point has something to stick into. The drills used will have a square tapered shank that will fit into a square tapered socket the end opposite to the pointy end. To use, you have a spanner on the hex section which winds the pointy bit out (its on a thread) as you turn the drill around using the ratchet handle. Slow but it was used before Mag drills and rotabroaches. Still usefull to drill large holes for example on steel bridge repair, where you havent a large amount of holes to drill but the position is difficult re headrom etc for a mag drill.
We used strongarm with a big rightangle air drill to drill 10off 27mm dia holes in our 5cwt massey anvil which was still in situ, to repair a broken dovetail. We placed a large slab of 100mm plate on the hammer bed plate as close to the anvil as I could get it, then welded a piece of 50dia bar vertically and swung the strongarm off that so as we could reach all the marked hole positions on our anvil.

I agree, i think its a hand drill wrench, ive used the underwater when i was a commercial diver, or something very similar, very effective for big holes.

Thanks to all the info that came back as to a brand name it may be DOMINO or known as a Domino tool (Stamped on it) cheers might have to see how much it goes????

A tool very similar looking to this was used for setting the headspace on PAK/HOW guns. But with the advent of chargebags became obsolete.
