Product Description

DHD380 Spline Down Hole High Air Pressure DTH Hammer for Geology Drilling

Product Description

Features of DTH Hammers:

1. Hammer Body: The hammer body is typically made of high-quality steel to withstand the high impact forces generated during drilling operations.

2. Piston: The piston inside the hammer is designed to transmit the impact energy from the compressed air to the drill bit efficiently.

3. Valve System: DTH hammers are equipped with a sophisticated valve system that controls the flow of air and regulates the impact frequency, ensuring optimal drilling performance.

4. Bit Retention System: A reliable bit retention system is essential to prevent the drill bit from becoming dislodged during operation, ensuring continuous drilling progress.

5. Different Sizes and Types: DTH hammers come in various sizes and types to accommodate different drilling requirements, ranging from small-scale exploration to large-scale mining projects.
