4X FASTER FROM PILOT BORE TO PULLBACK

Change from pilot bore to backream with a pit as small as 18" in diameter with the patent-pending Tri-Con non-threaded connection. Did we mention you can also change bits four times faster than conventional setups?

FREQUENTLY ASKED QUESTIONS

How often should I be changing my Tri-Con Coiled Pins?

Short Answer: Replace as soon as you see any signs of wear or mushrooming. This can be as frequent as each shot, depending on jobsite conditions. Consult the user manual.

Correct use: Before and after each bore, inspect the coiled pins, and mating components for wear or deformation. Keep all contact surfaces clean, apply light grease where applicable, and replace pins that show wear to maintain smooth rotation and fast tool changes

Technical details: Coiled pins are designed to protect the Tri-Con connection by absorbing wear during operation. They are purposefully a wear-item to protect the integrity of the Tri-Con Connection.

Incorrect use includes: Reusing damaged or worn pins or allowing debris to build up in the connection. Incorrect use can introduce greater risk of poor fit, difficult tool changes, or reduced connection performance.

What are Tri-Con Adapters compatible with?

Short Answer: Tri-Con Adapters are compatible with matching-size Tri-Con tooling and standard threaded HDD connections.

Correct use: Tri-Con Adapters are used to transition between Tri-Con connection tooling and adapters, reamers, housings, or other accessories. The adapter must match the Tri-Con size on one end and the correct thread type and size (Pin or Box) on the other.

Technical details: Compatibility is determined by Tri-Con size designation, thread type, and the torque and pullback limits of the drilling setup. Using the correct adapter ensures proper load transfer while maintaining the quick-change benefits of the Tri-Con system.

Incorrect use includes: Mixing Tri-Con sizes, using an adapter with incorrect thread orientation, or exceeding the rated torque of the smallest connection in the string. Incorrect use can introduce greater risk of connection wear, thread damage, safety risk, or failure.
