Introduction

The back hammer may be mounted on the drill pipe joint between the borehole gripper and the swivel head, thus creating a combined effect of effective reverse impact and vibration.

Sturdy and reliable, the back hammer is composed of three components and a plastic housing which acts both as an exhaust emissions guider and a muffler. With regards to the maintenance, it's only necessary to keep it clean and the linking section we protected when the back hammer is not in use.

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

 

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.

DTH back hammers are used for dealing with the stuck drill, hit up to solve the stuck drill problem.
