DTH Drill Bit
Here at YG Machinery, you can not only find different types of DTH drilling machines but also DTH bits. 2.5 inches, 3.0 inches, 4.0 inches, 5.0 inches, and 6.0 inches are all available to you here. We can even customize a particular DTH drilling bit for you according to your needs. Drilling bits in Yugong have a durable and efficient performance, and they are corrosion-resistant and have high tensile strength with good quality. So please email us if you need DTH drilling bits and other drill bits used in water well drilling rigs.
DTH Drilling Method – Working of DTH
- In DTH drilling, the percussion mechanism, commonly called the hammer, is located directly behind the DTH drill bit.
- The drill pipes transmit the necessary feed force and rotation to the hammer and bit, plus compressed air or fluids for the hammer and flushing of cuttings.
- The drill pipe is added to the drill string successively behind the hammer as the hole gets deeper.
- The piston strikes the impact surface of the bit directly, while the hammer casing gives straight and stable guidance to the DTH drilling bits.
