Tri-Con™ Tools & System
The Tri-Con System is a threadless connection system designed for HDD drillers to quickly change pilot bits and attach reamers or pulling attachments directly to the housing without needing breakout tongs. The unique triangular mating connection is secured with durable coil pins. The 2-5/8” Tri-Con connection is designed for 24,000 lb class drills and can ream up to 10” in many conditions.

A NEW TYPE OF THREADLESS CONNECTION
The Tri-Con System & design efficiently transfers the rotary torque, but without the sharp corners and stress concentrations of splined connections.
