A flushing current collects the loosened drill cuttings and conveys them upwards.

What is a down the hole drilling machine?

A down the hole drilling machine is a tool used in the drilling process to reduce the energy loss caused by the impact energy transmitted by the drill rod. By making the impactor dive into the hole, it reduces the impact of the hole depth on drilling efficiency, allowing for a faster rock drilling speed.

What is a down-the-hole drilling method?

The video shows the down-the-hole drilling method for very hard soil or rock. A rotary drilling rig, type LB 20, working with down-the-hole hammer inside a casing. A flushing current conveys the loosened drill cuttings upwards and exits at the upper end of the casing.

How do you drill a rock with a DTH hammer?

This method is mainly applied for hard to very hard rock and/or for penetrating large boulders. 1. Setting the DTH hammer with drill rod and casing on the drilling point. 2. Rotary and percussive drilling of the drill string under compressed air supply. 3. After reaching the final depth, unlocking of the drill rod with DTH hammer and pilot bit.

What is a spiral flush drill & how does it work?
