We have high-quality dth rock drilling bits. DTH drill bits can meet the hardest conditions, offering optimal solutions for drilling. Every bit, made from high-quality tungsten carbide steel, is a precision machine 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.
