Actually about $50-$80 which is why I made my own for much less. The
chisel tip I used cost a few bucks at Harbor Freight. I cut it in half
and ground the chisel half to shape so it could still be used in the
demo hammer. The other half of this hex shaped tool was a
drive-it-in-with-a -hammer fit to a short scrap of conduit. The conduit
went from round to hex as it was formed by force. With sufficient
conduit driven on you could "secure" the conduit to the tool with
tape. I lightly tack welded mine and when the weld failed I SERIOUSLY
welded it and it is still holding after many uses. Tape would also
work. The conduit is to keep the driver from slipping off the copper
clad rod. It doesn't transfer any mechanical force to help drive the rod.
