Downhole Innovations, Made in France HOME DRILLSTAR OIL AND GAS SUBCONTRACTING NEWS & MEDIA CONTACT PILOT MILL PDF info sheet FAST AND DEPENDABLE CASING MILLING DRILLSTAR Pilot Mill is ideal for milling tubular fish, cleaning a casing head before running casing patch and suppressing the damaged parts of a casing. Due to the pilot bit located below the blades, DRILLSTAR Pilot Mill can be perfectly directed to the target on the fish head, avoiding side tracking. Mud circulation holes between the blades facilitate the easy evacuation of cuttings. The pilot is hardfaced for optimum resistance to wear and enables perfect, smooth guiding of the milling blades. The blades can be hardfaced with either TOPLOY tungsten carbide grains or tungsten carbide cutting inserts. All features (Pilot diameter, fishing neck, number of blades, etc.) remain customizable to your needs.
