R32 Anchor bolt anchor drill bit for rock bolting

Dth drilling a down-the-hole drill, usually called dth is mainly a pneumatic powered rock or ground drill, in which the percussive hammer is located directly behind the drill bit, so the percussion mechanism follows the bit down into the drill hole. the drill pipes transmit the necessary feed force and rotation to the dth hammer […]

Down-the-hole (dth) rockmore international manufactures the finest and most efficient dth hammers and bits for the mining, construction and water well industries.

As a rule of thumb, the smallest hole diameter a dth hammer can drill is its nominal size. i.e. standard 102 mm (4”) hammer will drill a hole down to a minimum diameter of 102 mm (4”). the limiting factor is the outside diameter of the hammer, because as the hole diameter reduces due to diameter wear of the bit, airflow is restricted.
