Description

28Inch DTH Hammer With Shank TH28 Bit For Large Hole Foundation Piling Water well drillinging

"Down The Hole" (DTH) hammers provide the most versatile and cost effective rock drilling method available to date.

​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.
