Portable electro-pneumatic drill apparatus

摘要: A portable drill apparatus combines an air motor that drives a chuck in rotation, linear actuator the and reciprocating movements, electric operates actuator. The chuck, motor, actuator, are all connected together, end to end, enabling be easily manually transported positioned. separate programmable controller communicates with electro-pneumatic controls operation of perform peck feed drilling on layers different materials, power countersink controlled depths.
