Because of economy and powerful drilling capacity, down the hole hammer become an advanced drilling tool for drilling and mining industries. Down the hole hammers and drill bits are designed together to work in perfect unison, giving high penetration rates, long service life and low costs. 1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of hd series dth hammer designed according to newest rock drilling theory. 2. Smooth performance and long service life of hd series dth hammer due to high quality alloy steel materials and advanced processing technology adapted. 3. Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer. 4. Easy to depart bit from hammer due to multihead thread connecting chuck and cylinder of hammer. 5. Interchangeable with dth bit and drill pipe Low pressure and high pressure hammers are available in our company.

A rotation drill rig, air compressor and the "DTH drill string" are the essential unit for DTH drilling while the "DTH drill string" is always made up of DTH drill rods, DTH hammer and DTH bits. As one of key component, the DTH hammer acts as a role of converting the air pressure to the impact energy, simultaneously transferring impact energy and rotation force to DTH bits. The optimum range of hole size for blast hole drilling with DTH is 90 mm to 254 mm (3 -10). Smaller blast holes are generally drilled using tophammer, and larger holes generally use rotary machines. In other applications, like foundation drilling, DTH hammers can be used with single bit in hole sizes up to . 750 mm (30). With multiple hammer units CD (Cluster drills) drill holes up to 70 or 1778 mm. As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. A 4 inch hammer will drill a 4 inch (102 mm) hole. The limiting factor is the outside diameter of the hammer, because, as hole diameter reduces, airflow is restricted. Maximum hole size for production drilling is the nominal hammer size plus 1 inch, so for a 4 inch hammer the maximum hole size is 5 inch (127-130 mm). Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.
