The Best Bit in Hardpan and Small Cobble. 

The HammerHead^® TriHawk^® II drill bit is designed to perform best when drilling in dry compressed soil conditions and is a good choice when drilling in hardpan, dry clay and any other compacted soils. Operators can often achieve better steering corrections than with other rock bits, yet it maintains the ability to carve or steer in soft rock. The bit mount nozzle can be configured 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.

Economical design
A low-cost alternative for soft abrasive conditions and the replaceable bits often cost less than a rebuild on conventional rock bits.

Boltless mount
Eliminates bolts used to hold flat blades, which can come loose during tough bores.

Reduced operating costs
The boltless modular design of the square drive spline allows for interchangeable bits.

Wear resistance
All key wear areas have substantial amounts of carbide. The effect is greatly enhanced tool life between rebuilds.

Versatility
The boltless modular design square drive spline for the TriHawk drill bit assembly allows for interchangeable bits. Overall, the design and versatility of the modular TriHawk system saves time and provides versatility.

Bit adaptors
Because of the TriHawk® front high torque square drive spline, tooling can be changed quickly. TriHawk bits or bit mount attachments are installed 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.
