Feature Advantage:
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. Adriller commonly has three basic bits head designs: Flat Face, Convex and Concave. These are designed for specific applications for all rock types, hardness’s and conditions
