The Best Bit in Medium Rock Up to 12,000 PSI.

With all the fine qualities of other TriHawk^® bits, the TriHawk III features greatly improved abrasion resistance and significantly longer-lasting teeth. It is a good choice for soft to medium rock up to 12,000 psi (827 bar) or cobble bores.

Carbide grit is not only applied to the bit surface, but also into grooves that are cut into high wear areas. This application of welded grit carbide keeps the bit surface smooth, resulting in less resistance when pushing to steer.

Huge teeth on the TriHawk III drill bit provide plenty of surface area for abrasion protection of the bit face and tooth pockets. Drilling fluid is delivered through two water ports improving fluid flow during direct thrust and reducing plugging.

Cutting ability
Utilizing a center cut pattern, harder conditions can be cut productively. Larger teeth extend tooth life and reduce the need to “trip out” on long bores to replace worn teeth.

Pull back pin
The patent-pending pin installs quickly in the tooth pocket, allowing direct utility pull-back without bit or housing removal.

Wear resistance
All key wear areas have strategically placed carbide that assists in pulverizing the soil and allows for easier flow out of the bore hole.

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

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.
