Product Description

Product Description

      Drill Collars are one of the parts of a drill's string. Drill for the Collars is meant to provide weight for drilling purposes. The Drill Collars are thick walled tube like pieces that are machined from solid steel bars, although they are often made from plain carbon steel or the non magnetic alloy of copper and steel or other premium alloys that are non magnetic in nature. Drill collar has bars of solid steel that are drilled from one end to the other to provide a passage for pumping the drilling fluids through the collar.

      Collars that are available for drilling have an external diameter that is made of steel and can be slightly machine perfected for making sure of the roundedness. Drill Collars are sometimes perfected with the help of spiral Collars or helical shaped grooves. Drill threaded collar have connections that are male or one end and female on the other and. These are cut into a multiple collar that can be adjusted with screw along with other down hole tools. Drill helps make a bottom hole assembly or BHA.
