    hello to all group members,

    please tell me were i can get
    a small ultrasonic driller for drill holes in hard granite stones with
    the depth of 2 inches and the diameter of holes is 5m.m to 10 m.m.that
    driller must be able to carry by a men.
  2. An ordinary electric drill with a hammer option will do the job using
    tungsten carbide bits. You will need an inverter if you want to run the
    drill off a car battery. Are you collecting samples for analysis?

    How about a hammer drill ?

    May not do smooth work but it'll sure place a hole
    in that rock! :)

    The OP should look into the drills that cavers use when
    placing climbing bolts. Cavers have *serious* constraints
    on battery weight/life, since the drill may need to be lugged
    for many hours through rugged passages to get to where it
    is needed.

    Best regards,
