Solitary ring system for down the hole hammer

DTH SR products are economical and cost-effective to use when the ground is homogenous with few small boulders. With the same pilot you can install piles and interlocked Pipe-Pile-Wall piles just by using ring bits with different outside diameters. Robit® Solitary Ring Casing Systems are available for all the common Down The Hole hammers and can be used for all applications where the casing is left in the ground.
