Down The Hole Hammer Introduction

Reverse circulation drilling is also called central sample collection or double-wall drilling. This type of drilling usually uses a double-wall drill pipe. Drilling force is high wind pressure gas, which enters into the hammer through the gap between the outer pipe and the inner pipe. The hammer hit the drill bit to break rock, and the broken rock is collected into the pores on the drill bit surface, and then the rock samples are collected through the sample collection pipe and the drill pipe.

Down The Hole Hammer Features

1. Simple internal structure, good rigidity of parts, ensuring the long service life and convenient maintenance.
2. Collection tube is an integral type, which can be replaced without removing the hammer. After carburizing treatment, the collection tube is good in wear resistance.
3. With the patented design of the drill bit, it only needs to replace the drill bit. The same hammer can be used for holes of different sizes, and the samples can be guaranteed to be free from contamination.
4. The sampling work can be done well, even under various difficult conditions such as loose soil, hard rock and large amount of water.
