nice find

Looks like a bit to me. The holes would be for moving material up and out behind the drill head.

I found similar pieces with other drilling/mining equipment at an old gold mining camp in Canada.

Maybe part of a heavy duty house jack ?

Hi: a replacable bit for machine drilling holes, basically in mining. Being about 1 " in diameter, that is the size of a standard stick of explosive no?

I have a box of them in back.

P.S the threads are rounded not sharp or square.

Bunch of correct responses here. It is a bit for drilling rock for explosives. It is flushed with water that comes out of the hole in the center which carries that pulverized rock out along the sides of the reduced shaft. I have one that is three feet long and about 1 3/4 inches in diameter.

Digemall is correct, it is called a rock bit.... it is attached to a long normaly hexagonal shaft called a jumper rod with a hole right through the centre, this is where water is passed through to keep the bit cool. Those cutting edges are normally very hard (Tungsten) as they have to drill into rock. I used to sharpen these on a gold mine that I worked on. Ours were called button bits, ours had buttons of tungston instead of blades for cutting.
The threads will also be very course and left handed.
