Product Description
Hammer bits use pneumatic impact force to accelerate drilling progress, and are widely used in various mining scenarios such as blasting down-the-hole rock drilling, water wells, oil wells, metal mines, etc., and are of great help to drilling projects.
The high air pressure DTH impactor has the advantages of fast action, large impact power, low air consumption and long service life.
The impactor is designed with a strong blowing system, which can use all the high-pressure gas for slag discharge and keep the bottom of the hole clean.
The impact hammer has a simple structure, uses wear-resistant parts, and the product lasts longer. The front joint is connected with the outer cylinder by multiple threads, which makes it easier to disassemble the drill bit.
