| abstract | The utility model relates to a workover tool, mill the awl promptly. The left-handed spiral alloy groove is characterized in that the alloy groove is welded into a left-handed spiral alloy groove with an included angle of 15 degrees with an axis, wherein the alloy groove is formed by welding a taper part of the windowing section, the trimming section and the gauge section; the alloy grooves of the tapered parts of the gauge section and the windowing section are six cutting alloy grooves and six supporting grooves, the cutting alloy grooves and the supporting grooves are alternately arranged, two rows of YW 2A 116 blades are embedded in each cutting alloy groove, and 3-5mmYD hard alloy is paved and welded in each supporting groove; the trimming section is eight trimming alloy grooves, and 3-5mmYD hard alloy is paved and welded. Each milling cone of the product can be windowed for 2-3 ports, so that the production cost is greatly reduced, and the service life is prolonged. |
