What are the Advantages of DTH Drilling?

1. The down-the-hole impactor has large impact force, high drilling efficiency and higher drilling speed.

2. There is no lining (nylon tube) inside the drill bit, which prevents thermal expansion, cold contraction and damage of the drill bit during use.

3. The internal structural size of the down-the-hole impactor can achieve optimal energy transfer, large single impact power, and fast drilling speed.

4. The down-the-hole hammer has a special cone deceleration design. If there is gravel or soil blockage during drilling or the taper increases during drilling, the change in diameter will reduce the lifting resistance and greatly reduce failures.

5. In order to prevent dust pollution during drilling operations, the main components of the down-the-hole hammer adopt special computer program heat treatment technology, which is conducive to adding a small amount of high-pressure water to the compressed air for wet drilling protection.

6. In this design of the down-the-hole impactor, the user can directly connect to the drill pipe without changing the joint diameter, thereby reducing the user's production cost.

7. The down-the-hole hammer uses the best raw materials and the most advanced processing technology, with more stable performance and longer service life.

8. The internal structure of the down-the-hole hammer is the simplest and most reliable, easy to disassemble, has few failures and is easy to maintain. Since all parts are heat treated, there are fewer failures and easy maintenance.

9. Valveless gas distribution down-the-hole hammers are more reliable.

10. More efficient energy transmission, faster drilling, lower air consumption and lower fuel consumption.

11. Since the top connection piece is easy to disassemble, the drive chuck and the outer cylinder are connected with multi-threads.

12. Please note that down-the-hole hammers are designed to drill holes in a variety of rock requirements. It is worth noting that when the piston of the down-the-hole impactor comes into contact with the drilling rig, the transmitted energy will not be lost as the impactor goes deeper.

13. It can be hardened to extend the service life of the down-the-hole hammer and reduce the use cost of the down-the-hole hammer.

14. The piston and drill bit of the down-the-hole impactor have optimal momentum transfer.

15. The structural design of the down-the-hole hammer adopts modern theory, making the stress wave longer, the stress amplitude lower, and the piston life longer.
