5 FAQs about [Down-the-hole drill basket production video]
What is a down-the-hole drill?
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.
What is down-the-hole (DTH) drilling?
Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.
What are the advantages of using down-the-hole drilling tools?
The advantages of using down-the-hole drilling tools are numerous. They offer faster penetration rates and lower energy consumption compared to other methods, making them ideal for large-scale projects. Additionally, DTH drills are versatile and can be used in a wide range of geological formations, from soft soil to hard rock.
What makes a DTH drill system different from other drilling systems?
The advent of tungsten carbide for the drill bits (the first bits were all-steel) and the development of the button drill bit coupled with the introduction of high air pressures (25 bar plus) has meant that the DTH system can compete easily and efficiently with other drilling systems.
How does a down-the-hole hammer work?
The down- the-hole hammer uses the rotary percussion cutting action through the use of a button bit. This system is best suited for well consolidated formations, offering excellent penetration rates. Compressed air provides the percussive energy to power the hammer. The resulting exhaust removes the cuttings. Note the quality of the cuttings.
