    Quality Drilling Overshot Assemblies and Options for Your Operations

    We offer a complete range of overshot assemblies and options compatible with popular industry coring systems to enhance functionality in drilling operations.

    EdgeLOCK™ Overshot Assemblies – Rolling

    The Rolling EdgeLOCK Overshot is a modified version of the standard EdgeLOCK Overshot. It is normally used when the hole angle approaches 45° and the overshot descent time is compromised by friction between the Overshot Assembly and the inside diameter of the drill string.

    EdgeLOCK™ Overshot Assemblies & Options

    The EdgeLOCK Overshot is a simple, self-locking, compatible solution to retrieving the Inner Tube Assembly efficiently and reliably. When drilling down holes, the unique EdgeLOCK mechanism housed within the Overshot Head ensures that the lifting dogs are physically unable to release the spearhead.

    Overshot Spares

    Overshot Spares include all of the most commonly consumed overshot wear components. The EdgeLOCK Overshot spares kits contain pins, bearings, springs, nuts, fittings, pin links, screws, and lifting dogs. The pump-in overshot spares kits contain the same items, less the EdgeLOCK components.

    RetroLOCK Overshot Assemblies & Options

    The RetroLOCK Overshot is a simple, self-locking, compatible device for retrieving the inner tube assembly efficiently and reliably. The RetroLOCK latching system is our version of the most common overshot locking system used today.

    RetroLOCK™ Overshot Head Assemblies & Options

    The RetroLOCK overshot head assembly is our version of a well-known system with traditional overshot locking.
