Features :

An alternative to couplings is to include the female part of the threaded connection as an integral part of the drill steel. Male/ Female drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. The advantages of drilling with M/ F steel include: easy handling, quicker uncoupling, tighter connections and the potential to drill straighter holes.
