Got a hammer drill with a 3/4" bit to drill random holes and then use a hammer and a largepointed chisel? RENTAL STORES RENT ELEC BREAKERS AND BITS FOR LESS THAN 60.00 You're almost there ,that tool you're using is working you to death. The large elec breaker will take you longer to wrap up the cord and put it back on the truck than it will to break out the concreteLOL You Can Do It!!!!!!!!!!!!!
