A stabilizer system articulates at least one blade independently of an extendable blade for a through tubing mill. The stabilizer can be actuated with flow, pressure or set down weight. A piston responds to flow or pressure from the surface and an elongated member can cam out the stabilizer with set down weight on the extendable blades.

A running tool for a subterranean tool releases hydraulically. When used with a whipstock and anchor, the running tool can be dovetailed to the whipstock ramp to allow transmission of torque and downward force on the whipstock when positioning. An upward force can be transmitted to the whipstock from collet that is supported by a ball seat. The anchor is set and a passage opened through the anchor before cementing. The running tool is then released and a passage is opened for cementing. Release of the running tool results from shifting the ball seat that supports the collet. Cement can then bypass the seated ball and back through the ports in the ball seat. Removal of the running tool is assured by applying an upward force without needing rotation or other string manipulation that can be difficult in a deviated borehole.
