First of all, according to the geological environment to be built, determine the type of top hammer drilling tools to be purchased. Due to the different drilling geological conditions, economic strength, and production scale, different drilling rigs should be selected to achieve high efficiency and high output. How to choose should also understand the characteristics of the rig, such as which rig is suitable for the height of the deep underground, which rig is suitable for drilling into soft, medium, and very hard formations, and understand the working conditions of various types of rigs.

　　Secondly, confirm the quality of key components of top hammer drilling tools. The most important components of a drilling rig are the engine and hydraulic components. The quality of these components directly affects the life of physical equipment. Therefore, if you want to purchase durable anchoring equipment, you must first consider the quality of the engine and hydraulic components.

　　Third, determine the performance of top hammer drilling tools. The top hammer drilling tools can be widely used in deep foundation pits, subways, tunnels, railways, highways, geological disasters, anchoring construction, and small pile construction, greatly improving construction efficiency.

　　Fourth, solve the worries of after-sales protection. As we all know, good after-sales service is an important part of the product.
