PDC Button for DTH Drilling


DTH drilling is the industry-standard method for drilling hard rock. DTH =down the hole because the hammer literally goes down- the –hole. Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rock types. DTH drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes. 

The DTH technique is easy and quick to adapt to a directional drill and is considered one of the best and most effective methods to drill high-quality holes as it produces lesser noise and vibration compared to other drilling methods making it ideal for cities. It can be used on both hard and soft rock and is extensively used in the construction, oil and gas, and water well industries.


DTH equipment consists of a hammer drill bit and a piston powered by compressed air. As the drill string rotates, the drill bit strikes down on the rock. The drill bit receives its striking power from a piston inside the hammer that is powered by compressed air. This action along with the rotational movement of the drill string crushes the rock efficiently. Since the piston strikes directly on the bit, energy transfer takes place down the hole with minimum loss of energy, allowing drilling to greater depths.

In the market, there are carbide DTH bits and diamond DTH bits. Compared with traditional carbide DTH bits, diamond DTH bits have the following advantages: 

1. The service life of the DTH bit is increased by more than 6 times;

2. The overall tool cost of the operation decreased by more than 30%;

3. The production efficiency of the operation is increased by more than 20%;

4. Make the target application that was impossible to complete once become possible;

5. Reduce the frequency of tool replacement and reduce the labor intensity of workers.


For efficient Down-The-Hole (DTH) drilling, you need high-performing drilling tools, which increase your productivity and sustainability, while reducing your total operating cost and emissions.
