Down-the-hole drilling has been a feature of dam anchoring and rock mass grouting in the U.S. for many decades. Until quite recently, this rotary percussive drilling method was synonymous with the use of compressed air. Within the last decade, however, increasing use has been made of water-activated, down-the-hole hammers. These provide many significant advantages, especially for rock fissure ...

drilling, other hole making processes like laser, plasma, electron and ion beam machining have high set up time, high initial investment and low material removal rate (MRR), thus are not so economical for small batch production. Therefore, micro-drilling is one of the preferred options as a hole making process. Micro-drilling involves fabrication of holes of very small diameter (micro-holes ...

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 ...

Air hammer drilling, sometimes referred to as down hole drilling, is used extensively in Michigan's hard rock areas. The bit used in this drilling method is essentially a pneumatic hammer operated at the end of the drill stem. Compressed air operates a piston which strikes the top of the bit at a very rapid rate. The cutting tips on the bit are made of tungsten-carbide which are extremely ...
