| •Description: We also manufacture an Xs GT R system when the casing needs to be retrieved and the crown bit to be reused. This system offers the same advantages when it comes to drilling a socket into bedrock with the same driver bit. The crown OD on this system is a little bit bigger than the casing OD. This is why the driver and the crown size have to be different from the Xs GT system. Like all of our retrievable systems, the crown can come with a plain flush OD or with an oversized OD, thus allowing for relief grooves on the outside to ease the retrieving process. •:Components: Over sized crown Plain OD crown © Georocfor, 2009
