Product Description

DTH Hammer are one of our main products. It is durable for being produced with advanced craftwork and good material.After many years search, we have rich experience in development and manufacturing high quality products, which adopted high-quality raw materials, advanced technology and passed through strictly inspection.

 

It has many Advantages as below:

1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption

2. Smooth performance and long service life

3. Low problem rate and easy to maintenance

4. Easy to depart bit from hammer

5. Interchangeable with dth bit and drill pipe

 

Low air pressure DTH hammer

HR series DTH hammer, a kind of valve-equipped low-air-pressure hammer with a single piston, a plate valve and a central exhaust structure. The compressed air is adopted as the driving force. To prevent dust pollution and get a better performance, some high-pressure water may be added into the air for wet rock drilling.

 

Main Characteristics:

1.The strong energy of single impact and the low energy consumption in rock crushing;

2. The weight ratio of piston and bit almost reaches 1:1 to provide long effective acting time, which leads to the improved efficiency in rock crushing and the extended service life of the drilling tools;

3.A good performance in central air exhaust and cutting discharge, which reduces the repeated crushing of rock;

4.A check valve device is available to drill holes under water.
