Availability:

With professional manufacturing experience in DTH hammer production, our factory can supply you with high pressure DTH hammers. It strictly matches with API standard and other Chinese industry standards.It is durable for being produced with advanced craftwork and good material.


High Air Pressure DTH Hammers are divided into two types: with foot value and without foot value, the details as follow:

1.High air pressure DTH hammer size from 3" to 12"(76mm-304mm)

2.Shank types including COP, QL,DHD, MISSION,HD,IR, SD,TD, etc.

3.Connect Thread : API 2 3/8" , API 3 1/2 , Reg-6 5/8"Reg etc.


Down The Hole Hammers has the following advantages:

1. Non-Blocking

DTH hammers are proved to ensure extremely low rate of blocking during it works.


2. High Efficiency

The well drilling equipment carries with larger power of impact frequency and torque, thus ensuring faster penetration. Compared with others, the efficiency can be improved 10%.


3. Longer Service Life

All surfaces of the DTH hammer and bits are treated by anti-friction and intensified technology. When used in deep-hole drilling works, it can reach at 5000 meters or more.


4. Excellent Cleaning Effect

This DTH tool has large air output, which specially designed for water well users and enables it to flush out cuttings in deep hole drilling works.


Applications for DTH Drilling Hammer

High quality high air pressure DTH hammer without foot valve mainly use in blasting,water well,oil,gas deep hole drilling.
