Drillwell Ltd - Casing - Advancer

The Drillwell 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 Drillwell 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.
