Big Hole High Hammer

We often encounter scenes in buildings where large bore pile holes need to be drilled into the rock, and large bore water Wells require large amounts of water.In this application scenario, the hole size is large, the torque of the drill tool is large, the drilling cost is high, and the risk is high.In view of the characteristics of this type of scenario, our company has designed a special large-bore hole impactor.

Main Features Of Big Hole High Hammer:

1. Using the latest rock drilling theory, optimizing the inside structure and the size of the air distrbution, to make the hammer drill tool obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.
2. For such projects as the drill bit break, retrieving very difficult, we specially designed a safe and reliable anti-shedding device for the bit.
3. The check valve can be replaced to replaced to the one with bigger air controlling hole to provide more efficient cutting discharge.
4. The top sub and the drive chuck have special thread, which can achieve an easier disassemble.
