    Drill Collar Definition


    A drill collar is a device used at the lowest part of a drill string, an important part of the bottom hole assembly (BHA). It is always a very thick-walled tube to apply weight to the drill bit. Normally, a drill collar is threaded at both ends, male on one and female on the other. Except for thickness as a special characteristic, a drill collar owns other unique features, gravity, rigidity, etc.
