4'' DTH rock hammer tools for DHD340/Cop44/SD4/QL40/Mission40/Wooke40

Product Description

A down-the-hole drill, usually called DTH by most professionals. The fast hammer action breaks hard rock into small flakes and dust and is blown clear by the air exhaust from the DTH hammer. The DTH hammer is one of the fastest ways to drill hard rock. 

In DTH drilling, the percussion mechanism - commonly called the hammer - is located directly behind the drill bit. The drill pipes transmit the necessary feed force and rotation to hammer and bit plus compressed air or fluids for the hammer and flushing of cuttings. The drill pipes are added to the drill string successively behind the hammer as the hole gets deeper. The piston srikes the impact surface of the bit directly, while the hammer casing gives straight and stable guidance of the drill bit.
