13/16 diameter, 21 inch long TE-Y fitting hammer drill bit.  These were obtained a few years ago in an airfield repair kit I bought at a government surplus auction.  They would have been used for drilling anchors into concrete runway to hold down temporary runway plating to cover bomb craters.  The pictures show the sole used one I have, which is not in this sale.  The bits in this sale are new and unused.

ebay default 5/10/15 % discount is setup for 1, 2, or 3+ quantities.  If actual shipping is less than estimator shows, I'll refund any  overage.
