Do you need the most reliable and productive drill head available? More HDD contractors are turning to the TriHawk® line of drill heads from HammerHead®.

Whether you’re drilling in rock, overburdened cobble or compacted soil, there’s a TriHawk drill head to meet your needs.

TriHawk drill heads are made of the highest quality, heat-treated alloy steel and feature strategically placed carbide to help punch through the toughest conditions while reducing wear and enhancing tool life between rebuilds.

The boltless modular design square-drive spline is the toughest tooling connection in the industry. This modular design makes it simple to change out drill heads and can be easily adapted to use standard flat or blade bits. Durability and versatility make the TRIHAWK line the most advanced line of HDD tooling available.


  • Smooth cutting action
    Bit design and tooth angle provide smoother cutting action, which reduces machine vibration.
  • Replaceable carbide-tip teeth
    Teeth are positioned for high production and reduced machine vibration. Multiple cutting tooth styles can be configured for different types of rock.
  • 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.
  • Reduced operating costs
    The boltless modular design of the square drive spline allows for interchangeable bits. One housing for all your drill tooling!
