Description

"Down The Hole" (DTH) hammers offers an extensive range of DTH hammers suitable for a wide variety of drilling techniques and environments.

Our designed for drilling piles in complex conditions with rock layers and hard boulders including hardest bed rock.

​1. Advantages of construction method

Use:DTH Hammer drilling is a good way to drill through cave formation and avoid stuck problem

Cave:When encountering caves,drill bit inclines to the cave.The stabilizer ensures the hole straightness

Bit stuck；One reason is cave encounter,the drill bit deviates,and the entire set of drilling tools inclines in the hole.The other,is hole collapse.A large number of rock or clay catch the drill pipe,resulting in bit stuck.Steel casing and stabilizer can resolve this problem.
