Product Description

Rock drilling tools factory KINGDRILLING professionally produce casing drilling system by DTH hammer which designed to drill and case a hole simultaneously through unstable ground conditions. The system consists of a driver bit,integrated ring with casing shoe.The internal flushing grooves together with the built-in casing shoes gives a good seal to the button of the drilling hole, and thus mini missing the disruption of the surrounding of the drill hole.

At clockwise condition, eccentric part expanded to bring the casing tube into hole. After finished, eccentric bit closed anticlockwise and then can be lift up by the drilling machine. This type is especially suitable for diameter 114-273mm.
