Product info

Rotary Drilling relies upon high rotational speeds and thrust without percussion to achievethe 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.
• Available in TCI (carbide buttons) and mill tooth configurations.
