If for instance your application involves drilling though a variety of rock types, with fractures or fissures, then a flat face design would likely give the best results. The flat face copes will with any ledges and tends not to get stuck or pinched in the formation.The other main type of face design is the concave. The concave design is suitable if the hole is particularly deep or if directional control is important. The drill string can often deviate from vertical, taking the path of geological least resistance. The inverted pilot design found on the concave face means that the drilling system can maintain vertical alignment and improve directional control of the borehole.
