We have a comprehensive range of DTH drill bits to match all conceivable applications. Each bit is made from quality alloy steel and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance, and fitted with precision buttons manufactured in-house. These are designed for specific applications for all rock types, hardness, and conditions. Bit life and penetration rate are the most important criteria in selecting the right bit for a particular application.
