Product Details


Products Description


A complete range of down-the-hole hammers means you can find the right product here at LEANOMS. DTH drilling is primarily used in mining quarries but can be used in other construction applications. The DTH hammer is used to drill holes in a wide variety of rock formations, the variety of which is still far beyond the original concept of the first gasoline-powered drilling. DTH drill bits are used with DTH hammers to drill holes in various rock types.


It features the following things:

1. Freed from the problems caused by foot valve expansion and contraction, and fracture.

2. Less energy is used, but more frequent impacts.

Drilling speed is 15 to 30 percent faster than using a foot valve.

3. Simple design, dependable components, long lifespan, and simple, affordable maintenance

4. Lessen your use of oil and air. Compared to the one with a foot valve, the oil consumption is about 10% lower.

Our mission:

Focus on drilling clients' requirements and challenges, and continue to help them reduce drilling

costs and create greater productivity. Make the drilling works more successful.
