Cemented carbide rock drilling tools have become a powerful tool in the modern rock mining field with their high efficiency and durability.

As the use time increases, , DTH hammer will also face various failure problems. Understanding these can help us better improve its working efficiency.

DTH hammer has the characteristics of high efficiency, energy saving and environmental protection, and it is also a component that realizes impact rotation.

This article mainly describes the difference between rock drill bits and down-the-hole drill bits, including definitions, categories, etc.

The DTH drill bit is a rock drilling tool with high efficiency, safety and environmental protection, simple structure and convenient operation.

Heat treatment process of shank adapters is important to improve their mechanical properties and wear resistance to obtain the desired hardness, toughness and strength.

Carburizing process is a regular surface treatment method, which can improve the efficiency and quality of rock drilling when combined with rock drilling tools.

This article mainly describes the performance requirements of steel for heavy-duty rock drilling tools, including the performance requirements for drill bits, drill rods and shank adapters.
