Atlas Copco Secoroc has a comprehensive range of DTH drill bits that have been designed to match all conceivable applications.


Each bit, made from quality tungsten carbide steel, is precision machined to produce a perfect body. They are then heat-treated to the right hardness, facilitating excellent surface compression and fatigue resistance. Manufactured in-house, each bit is finally fitted with the required shape and sized buttons.


We offer five basic bit designs: Convex, Flat front, SpeedBit, Concave, and Rocket Bit. These are designed for all types of rock, whether hard or soft, abrasive or fractured.


Features & benefits

  • Improved steel grade for better fatigue properties
  • Five basic front designs
  • Designs for all rock types
