Junk mill (or milling shoe) is used for milling downhole fallings by bottom or side surfacing wear resistant material, a tool for repairing top of fish. At the milling surface, the carbide particles are built up by welding, which plays a part of self-milling. It is used to mill the fallen substances, such as bolt, nut, tooth wheel, slip dog, fittings for deep-well pump, etc.

We could supply flat bottom junk mill, concave milling shoe, pilot milling shoe, pear type milling shoe and many other high efficient milling shoes, and various of milling tools.
