Bit Overburden Eksentrik
ODEX / peralatan Eccentric ngijini sampeyan kanggo pengeboran lan kasus bolongan jero bebarengan ing kabeh jinis tatanan, malah sing karo watu gedhe.
Cara kasebut adhedhasar bit pilot lan reamer eksentrik, sing bebarengan ngebor bolongan sing rada gedhe tinimbang diameter njaba tabung casing.Iki mbisakake tabung casing ngetutake bor ing bolongan.
Nalika nggunakake ODEX, bagean saka energi impact dialihake menyang tabung casing liwat Pundhak ing piranti guide, kang siji impact ing sepatu casing khusus ing mburi ngisor casing.
