Bit service life and penetration rate are the most important criteria in selecting the right bit for aparticular application.In most cases the focus is on productivity, so the bits of fast cuttings removal features are preferable to ensure the buttons are cutting clean, with the minimum of re-crushing.

DTH bit can subiect to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity. 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.
