Best-selling DTH Hammer & Deep Hole Drilling Expert

Worldrill's Mission series products without air tube have been the preference of the market. They are the best-selling products in the industry since they entered the market.

The product features are as below:

1. Low impact energy loss, high impact frequency, and drilling speed is faster than the same type with air tube.

2. The hammer piston, the weight of the DTH bit and the contact end face can achieve a golden ratio, which maximizes the transfer efficiency of the impact energy, thus with lower air consumption, more air and oil are saved compared with the same type with air tube.

3. It has simple structure and stable performance. The components have good reliability, so long life can be achieved. Maintenance is also simple with lower cost.

4. Impact contact surface and impact frequency are optimized. Moreover, it can achieve better slag discharge and faster drilling efficiency, especially in deep hole drilling operation.

5. The equipped DTH bit has fast drilling speed and good wear resistance. It does not need air tube, so the trouble caused by air tubes can be avoided, including air tube breakage, damage or the expansion and contraction of the tubes.
