Reply:What would you drill with something like these?
Reply:I like the welds in #2,3 and 4. Looks like it's ment to be decorative.
Reply:thats some nice work!
Reply:Almost looks like what I'd imagine they use to run pipelines under highways.I see them doing it, but have never seen the boring end of the machine.Neat work"Any day above ground is a good day"http://www.farmersamm.com/
Reply:Lots of carbide buttons on some of those.   Buncha $'s right there, unless they buy the less than industrial grade.
Reply:Mean looking machinery! very nice work...

Reply:I've never seen those configurations before.  I wonder what the advantage of the first bit is.Common sense in an uncommon degree is what the world calls wisdom.
Reply:Grimm,All that nice welding you mentioned is done with Hard Facing Rod. this is to prevent wear when rotating underground.The theory behind using these is a small (6" or 8" hole) is drilled first, then these bits are run to open the hole further. The high pressure water or other fluid (depending upon formation type) is pumped down the center pipe and is blasted out the nozzles shown to lubricate the cutters, cool the cutters and to flush the cuttings back to the surface, cleaning out the hole while drilling.The first 'Bit' (pic #2) looks like it was designed to cut in both directions (being pushed ahead or being pulled backwards). Larger drum-shaped bits look to be made where earth is softer. The open-framed ones have the cutters much closer together for use in harder formations.Lane

Reply:I know what hard facing is, I do a little myself. I've just never seen a patern like that. Thought it looked interesting.
