ABSTRACT:
A drill bit or other working tool is provided with driven end segments which are removably received in longitudinal slots formed in a shank. The slots bottoms are contacted by the driven end segments to align the working tool with the shank; and, slot side walls contact the driven end segments for transmission of torque to the working tool. The working tool and shank are formed separately, then connected together, and the shank is connected to and driven by a rotary device.
