Roschen Group Limited - Casing - Advancer
Roschen Casing Advancer has been designed to allow drilling and
casing to be carried out at the same time as one integral
operation.
This feature eliminates the need to drill the large diameter hole
with a Rock Bit, pull the drill rod string and Rock Bit from the
hole and then ream the casing back into the hole.
The integral operation makes the Roschen Casing Advancer eminently
suitable for drilling through overburden or sands and gravels.
It is also particularly suitable for Landfill Drilling
applications.
If you require to order any of the items above or a bespoke design
then please email or contact us.
