    Hello. I'm a home hobbyist who thought it would be fun to make my
    own semi-precious beads....pbbhhhhtt. I bought a rock tumbler and
    several kinds of rough. The best I've come up with for drilling the
    holes is diamond-coated 3/32" bits in a Dremel, and even though I
    performed the entire operation with the stone (tiger iron jasper,
    Mohs 7-8, I think) immersed in water for lubrication, I burned
    through two bits to make one 8mm long hole. The smallest regular
    masonry bits I could find were 3/16", a big hole for a bead. Without
    making a massive investment, is there a better way to do this? Are
    these bits just not up to snuff? What kind of investment would be
    required to do it right? Any suggestions would be appreciated.
    Thanks!
