       Diedrich Drill is proud to introduce our New Shock Overload Shear Coupling for the D-50 High Torque Drilling Rigs.

           The New Shear Coupling will replace your old kelly bar coupling and is designed to absorb heavy shock loads by shearing four shear pins.   This will protect and extend the life of universal joints,  your right angle drive input shaft and your transmission.  This could save you a lot of service cost and downtime. It only takes a couple of minutes to replace the pins and away you go!
