Multi-use system for down the hole hammer

In some overburden drilling applications the casing has to be removed from the ground. This sets higher requirements on the durability of the equipment. Double groove design* in the casing shoe and the best materials available guarantee that Robit® Multi-Use system does not fail even in the most difficult conditions. Robit® Multi-Use system is available for all the common DTH hammers.
