Sections - Import export

Section mills are designed for cutting and milling a complete section of casing. All models 4 1/2 in. OD and above are equipped with 2 sets of 3 knives: 1 long set and 1 short set, designed for first cutting and then milling the casing. Knives can be hardfaced with your choice of TOPLOY carbide grains or TOPMILL/SWORDFISH tungsten carbide inserts. For most jobs, TOPMILL inserts are strongly recommended to improve milling performance. This tool can be equipped with Flo-tel, which produces a sudden drop in mud pressure when the pipe is cut out, indicating the right time to start applying milling weight.
