Product description
Product introduction:
A down-the-hole drill, usually called DTH is mainly a pneumatic powered rock or ground drill, in which the percussive hammer is located directly behind the drill bit, so the percussion mechanism follows the bit down into the drill hole. The drill pipes transmit the necessary feed force and rotation to the DTH hammer and bit, as well as compressed air for the DTH hammer. Air flushes cuttings up from the bottom of the hole. Drill pipes are added to the top of the drill string as the hole gets deeper. The piston directly strikes the impact surface of the bit, while the hammer casing gives guidance to the drill bit. The fast hammer impact breaks hard rock into small particles, which are blown up by the air exhaust from the DTH hammer.

Product features
1.Precision machining using high quality materials ensures little breakdown and stable performance for a long time.
2.The adjustment of the plug in the hammer allows the air consumption to be controlled and the slime discharges smoothly done by maintaining the speed of air discharge in the hammer.
3.It has a built-in anti-return valve that can be used underwater.
Application
The principal drilling methods used in mines today are mechanical ones in which a drill drives cutting tools into rock by means of static or dynamic force. Percussion rock drills are the most commonly used equipment for drilling in small-scale surface or underground mining situations, whereas rotary crushing drills or down the hole drills (DTHs) are generally employed for mining in large-scale surface mines.
