★Product Description

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.

Maximum Energy Transfer: Fast drilling speed and low air consumption due to the special inner structure designed according to rock drilling theory.
High Durability: Smooth performance and long service life thanks to high-quality alloy steel materials and advanced processing technology.
Easy Maintenance: Low problem rate due to simple, reliable, and easy-to-assemble inner structures.
Convenient Operation: Easy to depart bit from hammer due to multi-head thread connecting chuck and cylinder.
Compatibility: Fully interchangeable with standard DTH bits and drill pipes.

⚙Main Applications

High pressure drilling rigs
Water well drilling
Bench drilling & Mining
Oil well drilling
Civil Engineering exploration
Mineral Exploration

Frequently Asked Questions

What makes the HD series DTH hammer more efficient?

The HD series is designed with a special inner structure based on the latest rock drilling theory, which maximizes energy delivery to the bit, resulting in faster penetration and lower air consumption.

Can these hammers be used for water well drilling?

Yes, these hammers are ideal for water well drilling, as well as mining, bench drilling, and civil engineering applications.

What materials are used in the manufacturing of the hammers?

We use high-quality alloy steel combined with advanced processing technology and stamping processes to ensure a long service life and smooth performance in tough conditions.

Are the DTH bits and hammers interchangeable?

Yes, our hammers are designed to be interchangeable with standard DTH bits and drill pipes, offering great flexibility for various drilling setups.

What range of hole sizes can these tools cover?

Our equipment covers a wide range of hole diameters, from 50mm up to 605mm, depending on the hammer size and type (3" to 12" models available).

Is a foot valve required for the drill bits?

For many of our high-efficiency models, a foot valve is not required in the bit, which helps in maximizing efficiency and reducing maintenance issues.
