Shandike DTH Bits for Rock Drilling

DTH (Down The Hole) drill bits are tools designed specifically for rock drilling and play a crucial role in the drilling process. For the success of rock drilling, nothing is more important than a drill bit that can cut various types of rocks straight and quickly.

DTH drill bits have a variety of face designs, button configurations, and handle styles, and are available in various sizes to adapt to different applications and geological conditions. For example, some manufacturers offer DTH drill bits with a diameter range of 2 “to 45” and are equipped with the most common face shapes, button configurations, and handle styles to meet specific drilling applications and rock formation requirements.

Choosing the appropriate DTH drill bit is crucial to ensure the smooth progress of the drilling process. The correct type, size, and configuration of drill bits will directly affect drilling efficiency, drill life, and drilling costs. Therefore, when selecting a DTH drill bit, multiple factors need to be considered, including rock type, drilling diameter, drilling depth, drilling speed, etc.
DTH (Down The Hole) drill bits are designed specifically for rock drilling, with a variety of face designs, button configurations, and handle styles to adapt to different applications and geological conditions. Here are some detailed information about DTH drill bits:

Structure and application: DTH drill bits are usually used together with drill rods and DTH hammers to form a complete downhole drilling system. The internal of the drill pipe transfers energy to the DTH hammer through compressed air or liquid, which has a drill bit that matches the hardness of the rock. When the hammer is pushed, it generates high-frequency impact force, hitting the drill bit and transmitting energy to the rock. At the same time, the drill pipe drives the drill bit to rotate through rotation, further cutting the rock.
Design and types: DTH drill bits come in various design forms, such as convex end face, flat end face, concave end face, and deep concave center end face. In addition, the hard alloy part often adopts a tooth arrangement method that shares ball teeth, spring teeth, or ball teeth and spring teeth. These designs aim to improve the cutting efficiency and durability of drill bits.
Material: DTH drill bits are usually made of hard alloys, such as Dewey alloy, which have excellent wear resistance and impact resistance, and can cope with various challenges during the drilling process.
Usage and Maintenance: When using DTH drill bits, it is necessary to follow some key precautions. For example, in perforation operations, it is necessary to ensure that parameters such as wind pressure, axial pressure, and rotational speed match the recommended parameters of the drill bit sample. In addition, the drill bit should undergo a visual inspection before being lowered into the well to ensure that it is intact and undamaged. When storing drill bits on the drilling rig, it is important to prevent dust and other debris from entering the interior of the drill bit.
In summary, DTH drill bits are a key tool in rock drilling, designed and manufactured to provide excellent drilling performance and durability. When selecting and using these drill bits, it is necessary to consider specific application requirements and geological conditions to ensure the smooth progress of the drilling process.
