5″ Direct Bore I – 2.875″ API REG. (P)-Direct Bore Bit


DirectBore Tooling is for those jobs that do not require a Railhead lncredibit. Made from the finest alloys available, the DirectBore tooling is available in sizes to fit 15,000 up to 80,000 pound drills. The box end on the housing allows the DirectBore Rock Bits to be screwed in without the use of any shims or pins. The Sonde Blocks can be clocked to align the sonde inside the housing. This is easily changed should the bit become over-torqued on the housing. The housings incorporate many features found in Railhead housing . Tri-lok doors reduce twisting of the housing and keep your electronics in place.

Housings require a Housing Saver which connects to the drill rod or quick connect system being utilized.
