PRODUCT NAME:
 DX-Y hydraulic casing section milling tool
DESCRIPTION:
 DX-Y hydraulic casing section milling tool falls down to the expected place on underground, revolving the drill string and opening the pump loop. Under the action of pump pressure，piston shaft moves down and its lower cone resists the back bevel of blade, which makes the blade spread outside and cut the casing pipe. When the casing pipe is cut off, pump pressure goes down, then put the drill pressure milling casing on. After pump stopping, piston shaft moves back with the function of spring. Under the action of gravity, the blade returns back the subject.
