Drill Collar Specification

Drill collars are used at the bottom of the drill string, just above the drill bit. They are used mainly for weight on the drill bit but also work as a shock absorber to dampen the vibrations and impact forces caused by drilling. There are two main types of drill collars, slick or spiral grooved, however both styles accomplish the same task. Spiral groove drill collars were introduced in more recent years and are thought to help prevent the drill string from getting stuck in the hole by allowing drilling debris and lubricant to pass more freely around the drill collar.

The size for Tubing couplings are ranged from3-1/8to 11
