GM Drill Collar

Superior Material

GM Drill Collar is made from 4145H modified quenched and tempered steel, ensuring exceptional strength and durability. Strict metallurgical specifications are followed to ensure consistent maximum depth of hardness throughout the entire length of the drill collar.

Impressive Hardness and Impact Value

With a hardness range of 285 to 341 BHN (Brinell Hardness Number) and a Charpy impact value of 40 ft-lbs, GM Drill Collar excels in performance. These impressive values are guaranteed at evenly distributed 16 points in any sections at room temperature.

Protected Connections

The connections on GM Drill Collar are completed and phosphate coated, providing protection against the elements and preventing galling upon initial make-up.

Cold Rolled Thread Roots

API and H-90 connections on GM Drill Collar have cold rolled thread roots, ensuring enhanced strength and reliability.

Thread Protectors Included

All drill collars equipped with standard connections come with pressed steel thread protectors, providing additional protection during transportation and storage.
