Product Description

Product Description

High air pressure DTH hammer is a kind of down-the-hole hammer. It is mainly used for percussive drilling in rock formation. It is characterized by high air pressure and high efficiency. It is suitable for use in areas with abundant air supply. The working principle of the high air pressure DTH hammer is to use compressed air to drive the piston to reciprocate in the cylinder, thereby generating impact energy to impact the drill bit and drill into the rock formation. The high air pressure DTH hammer has the advantages of high drilling efficiency, long service life, and good stability. It is widely used in mining, quarrying, construction and other fields.

Because of economy and powerful drilling capacity, down the hole hammer become an advanced drilling tool for drilling and mining industries. Down the hole hammers and drill bits are designed together to work in perfect unison, giving high penetration rates, long service life and low costs.

1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of HD series DTH hammer designed according to newest rock drilling theory.

2. Smooth performance and long service life of HD series DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.

3. Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer.

4. Easy to depart bit from hammer due to multihead thread connecting chuck and cylinder of hammer.

5. Interchangeable with DTH bit and drill pipe
