Drill Collars

The primary function of the drill collar is to apply weight on the bit. Drill collars do not have welded tool joints (such as integral HWDP) but instead have pin and box connection threads machined directly into the body wall. Spiral grooves may be cut in drill collars to reduce the collar's tendency to differentially stick.
