Valveless air distribution. More reliable. Simple design of the piston. Long life. More efficient energy transfer, fact drilling speed, lower air consumption and lower oil consumption. Fewer internal parts, simple structure, long life, less failure and easier to maintain because all the parts are heat treated. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
