Texoma TXC series digger derrick rock augers are made with 3/8 thick flighting. The auger stem is 3 3/4 inch O.D. C-1026 heavy wall tubing. The standard are TX56 and TX 58 carbide rock auger teeth and TX 205 pilot bit.

For increased performance the TX-50-C pilot bit can be used on these. This pilot will hold four TXC series rock auger teeth and will drill much better then the standard TX205 fish tail pilot bit.

Texoma TXC rock augers will increase the drilling performance of digger derricks in loose and compacted soils, stiff clay, shale, cobbles, and medium rock. The TXC rock rock auger teeth also last much longer then standard dirt auger teeth due to the carbide used.
