Product Description

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 Sandvik 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
