Downhole Directional Drilling Tools: HammerHead

March 2010 Vol. 65 No. 3

The TriHawk II drill bit performs best when drilling in dry compressed soil conditions and is a good choice when drilling in hardpan, dry clay and any other compacted soils.

Configure the bit mount nozzle for a variety of drilling conditions. Unlike flat plates, there are no mounting bolts to re-torque or come loose. The TriHawk II forging interlocks onto a bit mount incorporating T-slots and is protected by carbide on the leading and trailing edges. It is easy and economical to replace. A front high torque square drive spline means tooling can be changed quickly. Install bits or bit mount attachments by simply removing roll pins, sliding off one style of bit, sliding on another and reinstalling the roll pins. Indexing the steer plane to the transmitter is automatic when installing the bit. 800.331.6653, www.hammerheadmole.com
