Milling almost anything in the wellbore, including, but not limited to: bit cones, bits, cement, packers, squeeze tools, perforating guns, drill pipe, tool joints, reamers, and reamer blades.
Bladed junk mills, designed to mill any type of junk or debris from the wellbore. These "workhorses" of downhole milling operations can be dressed either with tungsten carbide inserts, for stationary fish or junk, or with crushed tungsten carbide, for loose fish or junk. Large circulation ports and watercourses improve fluids circulation for cooling and facilitate cuttings removal. The blade design holds junk to be milled under the milling face and cuts continually rather than sweeping the junk ahead of the blades.
