  • Looking for a genius to tell me what this is?

    So I'm bidding on some scrap steel on the weekend at an estate sale.
    i go to collect my steel and found a few of these things sitting behind the steel.
    they are about 30lbs each
    look to be a crusher or grinding attachment for something.

    If if you know what they are can you let me know wether to clean them up and sell them or take them to the scrap yard, or make a fancy anchor.
    thaks to all of you that can help me.

    They look like the business end of a drilling rig for either water or oil wells.

      They are tri-cone drill heads for rock, they worth something to the right person. I believe there is a company that buys / refurbishes them as long as they are not too bad, you just have to look around on Google

          Tri cone rock bit for in ground drilling rock.
          There sized by Dia. & thread type.
          By look of condition sell for scrap.
          The inserts are carbide but not easy to remove. I normally just sell for scrap as they wolnt pay for carbide unless cleaned.

            If i had found that i would have think i struck gold, I would have cleaned it (shot blasting, ultrasonic etc...), obviously i'm not from a drilling area.

            Is it the type of drill bit howard hughes patented when he was 19 years old for his father drilling exploitations ?

            Could it be used for drilling with these home made drilling machines that guys on many forums (maybe here too) are looking for plans??

            I think my english grammar sucks

                  No, too big and would take a lot of power.

                    Sell them to Snow Bird in post #6. He thinks they are gold. They are too worn out to use for drilling.

                      These bits look to be in bad shape but don't be too quick to scrap. There are people who buy and re-tip them.

                          yup you might have a few dollars there for sure. clean them up and give them a good coat of paint. try letting them soak in a bucket of deisel for a few days them wire brush them then soak them again til they are nice and clean.after that put them on ebay.as for scrapping them you might be able too if they aren't hotmost stuff thats been used for drillin is hot scrap yards won't touch it. to bad they wasn't diamond tip bits.
