Product introduction:

Down-the-hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powder to a down-the-hole bit to crush rocks.

Product advantages:

1. More efficient energy transfer.

2. Faster drilling speed, 15%-30% higher than others.

3. Lower air consumption and lower oil consumption. oil consumption is about 10% lower than others

4.The surface of the parts is treated with anti-fatigue strengthening treatment, which has a longer working life

5.Optimize impact contact surface, air chamber and impact frequency to achieve faster perforation efficiency
