Products Description
LEANOMS
A piston driven by compressed air within the percussive DTH hammer gives the DTH Hammer Bit its striking strength, and the DTH hammer casing guides the DTH Hammer Bit. The drill string spins while the drilling hammer constantly strikes down into the rock in DTH drilling. As the hole becomes deeper, additional drill rods are added to the top of the drill string. The DTH drill rods transfer the required feed force, rotation, and compressed air to the DTH hammer and bit. Fast hammer impact fractures strong rock into tiny fragments that are propelled into the air by the DTH hammer's air exhaust.
We provide a wide selection of DTH Hammer Bit in DHD, QL, SD, and other shank types to accommodate a variety of drilling needs. All alternative types are possible, but flat faces and spherical buttons are the standard DTH components.
failure analysis
LEANOMS
The four most frequent problems with DTH Hammer Bit are as follows:
1. the broken valve;
2. The hammer body jams once the fractured ballast from the drill head's tail enters the cylinder;
3. The vent was sealed by rock dust;
4. If there is too much water in the hole during chiseling downhill, the exhaust resistance will increase and the impactor will be difficult to start.
The following steps are the inspection procedure: elevate the DTH Hammer for a bit, lower the exhaust resistance, release some water, and then gently push it toward the bottom of the hole. If this approach is unsuccessful, it is probably due to one of the first three causes, in which case the hammer has to be taken apart for cleaning or component replacement.

How to choose
LEANOMS
When choosing a DTH Hammer Bit for a project site, it's essential to consider the specific site conditions. Here are some factors to consider:
Rock type and hardness: Different rock types and hardness levels require different types of hammer bits. Soft rocks like clay or sandstone may require a hammer bit with higher impact energy and a larger bit diameter. On the other hand, hard rocks like granite or basalt may require a more robust and wear-resistant bit.
Geological conditions: The geological conditions of the site, such as the formation structure and presence of water-bearing layers, should be considered. Certain geological conditions may pose drilling challenges and require a bit of better penetration or anti-clogging capabilities.
Drilling depth and diameter: The drilling depth and diameter influence the selection of the hammer bit. Larger diameter boreholes may require a bit with a larger diameter, while deeper drilling may necessitate a more durable and reliable bit.
Drilling speed and efficiency: Consider the desired drilling speed and efficiency for the project. Some hammer bit designs offer higher impact energy and faster penetration rates, while others may be better suited for higher precision and control during drilling operations.
Bit design and structure: Different bit designs and structures are suitable for different drilling applications. For example, a tapered bit may be suitable for general drilling, a spherical bit for harder rocks, and a flat-bottom bit for more precise exploration and coring operations.
