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. They are fitted with Roschen's
proprietary cemented carbide buttons, which are designed to drill
further. The drill bit bodies are made from precision hardened
nickel molybdenum steel, with a compound curve shape for faster and
smoother cutting and easier removal of cuttings.
The bits in the new range have an optimized head length with
maximized steel support for the cemented carbide buttons, deep face
grooves for excellent flushing and an aggressive cutting structure.
Advantages:
1. Proprietary superior tungsten carbide ensures high quality and
performance
2. Carbide grade options for long life in challenging applications
3. Face designs to maximize penetration rate and tool life
4. Optimized flushing designs to aid in cuttings removal and reduce
wear
