Rotary drilling is a method of drilling that employs a sharp, rotational drill bit to bite its way through the earth’s crust. It relies upon high rotational speeds and thrust without percussion to achieve the desired effect and outputs. In rotary drilling, the rock is made to fracture by means of a combination of “pull down” pressure on the bit and rotational power “torque”. Weight is applied to gouge, chip and grind the rock. Tricone rotary bits are sometimes a good alternative to a DTH hammer. It is used in the construction, mining, and oil industries as well as water & thermal wells.
