Drill Collars
Matrix Drill Collars are engineered to deliver precise weight on bit (WOB), maximizing penetration rates and eliminating compression drilling — two of the most common causes of drill string failure and increased cost per foot.
Machined from high-grade AISI 4145 alloy steel, every Matrix Drill Collar undergoes rigorous quality control during manufacture. Each collar features a DI-22 thread form and a stress relief groove in the pin tool joint connection, reducing fatigue failures and extending drill string life.
The result: fewer failures, less downtime, and lower cost per foot for drilling contractors.
