We offer a wide variety of new and used drill collar sizes from 3⅛” to 9½”, spiralled or slick, and with API and premium connections. Drill collars can be tailored to specific requirements and are constructed from a solid bar of AISI 4145H modified alloy steel.
All our new drill collars are furnished with mill certification, which we backup digitally in case certificates get misplaced.
