TX205C cast steel carbide tip fish tail pilot bit. Texoma "TX Series" digger derrick pilot bit. This is what starts the auger into the ground and keeps it centered in the hole. This is an upgrade pilot bit to replace what comes stock on (TXD) dirt and (TXC) carbide rock augers. This fish tail as well as the standard dirt fishtail will fit almost any style digger derrick auger pilot.
This carbide version helps not only cut drilling time but also increase the life of the fist tail.
