    What were you thinking for the counter sink portion? All I can really come up with is using a forstner bit but I'd hate to chew it up. If the rock is soft enough to get 100 drills out of it, it would be worth machining to accept a 3/8 drill bit. Most the stone grinders I can think of are too big, hole saws would take several sizes or some chisel action. I have a ton of vertical real estate in my new pico and think this would be perfect, I hate seeing plugs.

    I was originally about welding a couple of flat wings onto a drill bit, but I think that would likely jump around too much and make a mess of the rock.

    How about nesting a bunch of diamond tipped glass hole saws around the 3/8” drill bit? Glass hole saws are super cheap and you should be able to get a ton of use out of them when cutting something soft like calcium carbonate live rock.
