TRANSMITTER HOUSINGS AND BITS
Sonde Housings & Bits
Railhead
Railhead products are built tough and fit all major brands of mini-HDD machines on the market.
Dirt Boring Projects
The Endurance product line consists of a series of conventional bits and a sonde housing that is designed for contractors who do not drill in the kind of conditions that require an INCREDIBIT®.

Solid Connection
The key feature of the Endurance line is how we attach the bits to the housing. We've developed a keyway system that takes the side stress off the bolts which virtually eliminates the problem of drill bits breaking off the housing.

Durable Housing
While the Endurance housings are designed specifically for the Endurance bits, they incorporate many of the most popular features of our INCREDIBIT® housing, but at a much lower cost. We've used the Tri-Lock door and sonde blocks to protect the transmitter. We also use housing savers so, if the threads get messed up, you don't have to buy a whole new housing. We believe the Endurance housings will outlast any other dirt housing that's on the market today.
Versatile
The Endurance line uses all of our current connections to the most popular HDD machines, including the Railhead Quick Connect System. For contractors who use the INCREDIBIT®, the Endurance bits are designed to also fit the INCREDIBIT® housing.

Reliable
From the INCREDIBIT® to the Endurance line, Railhead's products are designed to provide contractors the ultimate reliability in downhole tooling.
Rock Boring Products
Railhead's INCREDIBIT® drill head is named for its ability to bore and steer through tough, rocky conditions. Its patented technology allows contractors to accomplish bores in ground that cannot be drilled with conventional bits. Andit allows smaller machines to drill through some conditions that would otherwise require a mud motor. It is truly a multipurpose bit that steers through soft conditions as well as rock and cobble.
