Eccentric Casing Bit (ODEX Drilling Tools), Casing Pipe, Casing Shoe
Eccentric casing bit is used to effectively drill holes in complicated formations such as loose ground, fractured formation and gravel layers, etc. Hole wall protection is usually needed during hole making process.
Our eccentric casing bit, casing pipe and casing shoe are commonly applied to complete high pressure jet grouting holes, cement grouting holes, anchor wire holes, drainage holes, blast hole, underwater blast hole, and the holes for trench-less underground pipe line and cable installation.
Due to our constant efforts, our eccentric csing bit has achieved a national patent. The Chinese patent number is ZL022581561.
