John Lawrie Tubulars offers 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 are tailored to clients’ specific requirements. Our collars 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 incase our clients misplace their certificates.
