A hammer is only as good as the bit it uses – and no bit is better than Secoroc DTH bits.  The economics of drilling often comes down to balancing penetration against bit life.  Roschen Secoroc bits improve drilling economy regardless of what hammer is used or whether optimized penetration rate or bit life is preferred.  


Roschen can help you match the right face design and button shape to your drilling application.
