To connect the drill bit with a drill rod you can use an adapter. It is included to kit with each drill bit. The adapter has a ready made thread for drill bit connection. On the other side you can make your thread for. [pdf]
The Boyles C5/C5C surface core drilling rig is compact, yet powerful. Its compact design makes it easy to position and transport, even by helicopter. During helicopter transport, the rig is broken down into six main modules and each module is equipped with lifting points to ensure safe and effective transport. Boyles. .

The MR–5 ID is a hydraulic drilling unit for using 2″ or 3″ down-the-hole hammer, or rock drill weighing 58 kg with separate right and left rotation, provided with a hydraulic power pack operated by an electric, diesel or petrol motor. [pdf]
This requires use of 3,000-hp rigs due to heavy casing hookloads for the 24-in. and 18 5/8-in. cas-ings, high mud weights at relatively deep depths in 16-in. and 12 1⁄4-in. hole sec-tions, and fairly high torques throughout the well. [pdf]
A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock. The system is thought to have been invented independently by Stenuick. Origin of the nameDTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanis. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the flui. [pdf]
The down-the-hole drilling machine is suitable for large-diameter blast hole rock drilling operations in small and medium-sized mines, road construction, water conservancy, and stonework, as well as dri. [pdf]
When choosing a down-the-hole (DTH) drilling rig，you need to consider various factors. This article will guide you on how to choose the right down-the-hole (DTH) drill from three important parts: drill bit, drill pipe, and impactor. .
The higher the working pressure of the down-the-hole drilling impactor, the faster the rock drilling speed. Since the drill impactor is designed according to a specific. .
The impact energy of the down-the-hole drilling impactor must ensure the specific energy of the drill bit, so as to effectively break the rock, and at the same time obtain a more. .
Generally, when the impact energy is constant, the higher the impact frequency, the greater the impact power. However, the outer diameter of the impactor is constrained by the diameter of the borehole. The higher the impact frequency, the smaller its impact energy. Therefore, the increase of impact frequency is limited by the specific. [pdf]
JK730-2 crawler mounted automatic rod exchange DTH drill rig is a hydraulic DTH drill rig. It is equipped with automatic rod changer for rod storage, changing and connecting automatically, as well as hole loc. [pdf]
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]
