All our DTH drill bits are also CAD designed, CNC manufactured for perfect bits body, and multiple heat-treated to enhance hardness, surface-compressed for fatigue resistance, all thus to extend the product life for maximum wear and performance in the toughest of drilling conditions. Moreover, all these bits are also made from high quality alloy steels and fitted with premium quality tungsten carbide tips for superior penetration rate.

To Chose the Right Products
When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life. We have different shapes of the face for you to choose :
