Ürün Açıklaması

Based on the characteristics of the wells, oil, gas and construction drilling, our company self-designed, developed and manufactured this kind of high air pressure DTH hammer.

It has the following characteristics:

1. Using the latest rock drilling theory, optimizing the inside structure and the size of the air distribution, 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 the one with bigger ail controlling hole to provide more efficient cuttings discharge.

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