Xs S system
Only complete overburden and rock drilling system on the market, the Xs S is made especially to give maximum clearance for sub-casing drilling. This 3 components system allow users to install the casing and to drill the rock portion with a bigger hammer in almost all the cases.
The Xs S (standard) system is used with any size of casing and is especially useful with thin wall casing. The crown has a socket which fits over the casing for better welding alignment.
