Product Description

12inch Quarry / Mining Rock Drilling DTH Hammer Bits with Heat Treatment High Performance

                              

Application                                                                                                                                                         

DTH (Down to Hole) drill bit, also called spline connected drill bit, is mainly used in large scale mine (open and underground), open quarry and construction. The hammer is situated down the hole in direct connected with the drill bit with splines in the bit. The hammer piston strikes the drill bit resulting in an efficient transmission of the impact energy and insignificant power losses with the hole depth.
 

Our tools are widelyused in different drilling applications including mining,quarrying, water well drilling, geotechnical industries and etc.

In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
All the products are manufactured as per the international standard and well compatible with the brand of Atlas Copco, Ingersoll-Rand, etc

 

• Underground mining
• Tunneling
• Quarry benching operations

Characteristics                                                                                                                                                  

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 multi—head thread connecting chuck and cylinder of hammer.

5. Interchangeable with DTH bit and drill pipe
