Product Description

Description


"NEW DIAMOND" DTH drill impactor work efficiently at the same time, reliability and long life is our product reflects its advantages. Impactors and drill bits are the worst in all industrial equipment and work environments are uncontrollable and unpredictable. With its high precision of the internal parts, the weight and the processing quality of each part of the impactor are ensured by the new diamond. The good lubrication conditions can greatly improve the efficiency, stability and life of the impactor.

Specifications


1. Using the latest rock drilling theory,optimizing the inside structure and the size of the air distrbution,to make the DTH hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.

 

2. For such projects as the drill bit break,retrieving very difficult,we specially designed a safe and reliable anti-shedding device for the bit.

 

3. The check valve can be replaced to replaced to the one with bigger air controlling hole to provide more efficient cutting discharge.

 

4. The top sub and the drive chuck have special thread,which can achieve an easier disassemble.

 

Feature Advantage


1. Fast drilling speed and low air consumption due to the special inner structure.
2. Smooth performance and long service due to high quality alloy steel materials and advanced processing.

 

Technology adapted


1. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner.

 

Structure of hammer


1. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
2. Interchangeable with DTH bit and drill pipe.

 

The appearance of the picture is different from that of the actual product, and the actual product is the standard.
