Details description:
Ground impedance type drill three key type and six key type two kinds, steel material adopt high quality alloy steel seamless steel tube, welding in the key on the road for high wear-resisting drive keys. Among key driven out, without pressure and pressure is down by drilling circle force generated by friction and transfer to drill. This drill can be applied in mud and sand and soft soil drilling neutral.
