Down the Hole
The Down the Hole business line covers all operations related to the down the hole drilling method. The main product categories consist of DTH hammer, DTH bits, DTH tubes, DTH casing systems and shock absorbers. The selection is the widest in the world and encompasses top quality products for all your applications: piling, bench drilling, production drilling, exploration, drifting & tunneling, horizontal drilling and further more.
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.
Robit offers TCI (carbide buttons) and mill tooth configurations.
Robit’s Reverse Circulation (RC) products help you drill deeper and faster and importantly delivering high quality samples for your customer. Reverse circulation is achieved by blowing air down the rods, the differential pressure creating air lift of the water and cuttings up the “inner tube”, which is inside each rod. It reaches the “divertor” at the top of the hole, then moves through a sample hose which is attached to the top of the “cyclone”. The drill cuttings travel around the inside of the cyclone until they fall through an opening at the bottom and are collected in a sample bag.
