It is Mainly made of ladder shaft shaped centralizer and using connecting pin installed in centralizer with eccentric bit, due to the connecting pin in full in the process of drilling torque, connecting pin put on eccentric drill bit and centralizer cylinder parts, it is very simple to use, driving ability outstanding ,slag discharge effect is perfect.

Some application for the reaming drilling tools:

Civil engineering projects: anchoring, goating, pipe and cable laying. Blast holes without soil removal.

Mineral prospecting: pilot holes for diamond drilling,sampling cuttings,overburden thickness surveys,water table studies.

Water wells: casting form surface down to bedrock,casting all through unstable formations,exclusion of upper water layers which are frequenty polluted.
