Eccentric Casing Drilling Tools


Description:
Eccentric drilling tool is composed of guide bit, broaching bit and a rod guide. This kind of drilling tools can be used with casing and DTH hammer. This method can effectively overcome loosen, crushed, sand and gravel formation and other complex formations. This product can be applied to the constructions of anchor holes and drain holes, etc. In the drilling process, the drill bit of the eccentric drilling tool expands a hole big enough. The casing follows the drill bit enter the hole. Dusts are blown out of the casing. When the drill hole reaches a certain depth, the drilling tool would rotate in the opposite direction. The broaching bit would be folded and overlap the guide bit. At this time, the drilling tool can be taken out of the casing.
