Drill Collars Rental & Sales
Slick & spiral collars for weight-on-bit
In short
Slick and spiral drill collars in a full range of OD/ID combinations to deliver weight-on-bit and keep the bottomhole assembly in compression.
Drill Collars for rent or for sale — drill collars rental, suppliers, sizes, grades and connections, delivered worldwide.
Drill collars are thick-walled steel bars that supply the weight-on-bit needed to drill ahead while keeping the neutral point above the BHA. We rent slick and spiral collars from 3⅛" to 11" OD, in API and premium connections, non-magnetic (monel) options for survey work, and with recessed slip and elevator areas for safe handling.
