DOWN-THE-HOLE BITS  
                   
Roschen DTH drill bits are fitted with our cemented carbide inserts, which provide you with superior life and drilling productivity.

The Roschen DTH button bit designs are well known and extensively used around the world. Whatever conditions you're dealing with, our drill bits make the job easier.
