DTH hammer is a percussion drilling tool used in various industries such as mining, construction, and oil and gas exploration. It is a vital component of the DTH drilling system. The DTH hammer operates by delivering rapid, repetitive blows to the drill bit, which is attached to the end of the drill string. These powerful impacts crush the rock or other materials being drilled, allowing for efficient penetration into the ground.

Extension drill rods are threaded on both ends, allowing them to be connected to existing drill rods or other extension rods, effectively lengthening the drill string. This extension capability enables drilling operations to reach greater depths without the need to replace the entire drill string, thus saving time and resources.

Drifting rods are drilling tools used in underground mining, tunneling, and other engineering projects. They are typically employed for excavation operations in underground projects, used for drilling blast holes, ventilation shafts, tunnels, or other underground structures.

Shank typically refers to the portion of the tool that connects to the drill string or drilling apparatus.
