PHASOR ORTHO offers (1) quick-connect interchangeable drill bit driver with (2) K-wire driver option.  Intended for distal upper and lower extremity applications. PHASOR ORTHO can engage bits from the "Small-Frag" sets, is compatible with other AO Quick-Connect Bits, but intended for smaller bone procedures.  The standard universal AO-connection allows for bits as well as the K-wire driver itself to connect, with variable sizes for differing K-wires.
