FZ-Ts junk mill is designed to destroy cement all across cased hole cross-section, to underream sand plugs and casing accessories, to mill metal objects at the bottom.
The junk mill consists of a body and a braze of hard-alloy inserts and tungsten carbide chips. The flank of the mill is hard-faced with hard-alloy bits and is durable for metal milling.
Convex form of the braze enables increased ROP when milling cement.
It has thread connection at the upper end, and ports and relevant watercourses for better cooling and more efficient removal of cuttings at the lower end.
