DTH drill bits are designed to make operations easier by drilling further, whatever the conditions. They have optimized head length with maximized steel support for the cemented carbide buttons, deep face grooves for excellent flushing and an aggressive cutting structure.
Design and quality
The drill bits are fitted with Sandvik's proprietary cemented carbide buttons, which are designed to drill further in any rock condition. The bodies are made from precision-hardened nickel molybdenum steel, with a compound curve shape for faster and smoother cutting and easier removal of cuttings.
Innovation and technology
The carbide grade option offers long life in challenging applications. PowerCarbide® SH69 is capable of increasing your service life by up to 45%.
Productivity and performance
The bit face designs maximize penetration and tool life, while optimized flushing designs aid in cuttings removal and reduce wear. Longer bit life, less downtime and superior quality all contribute to increased productivity and improved safety in drilling operations.
