Drill Collars
Matrix Drill Collars are used to achieve the correct weight on bit (WOB) to maximize penetration rates and prevent drilling in compression. Matrix Drill Collars are machined from high grade alloy steel corresponding to AISI 4145. Each collar undergoes rigorous quality control procedures during manufacture. Matrix offers a DI-22 thread form and a stress relief groove in the pin tool joint connection. By running Matrix Drill Collars, failures in the drill string will be reduced to a minimum resulting in less cost per foot for the driller.
