Overshot Assemblies and Options From Your Trusted Diamond Core Drilling Partner
Safely and efficiently retrieve your inner tube assembly with our overshot locking systems. Whether you need a full assembly, head assembly, or spares, Di-Corp Driller’s Edge has your overshot needs covered with options compatible with industry-leading coring systems. Keep your rigs turning and get more rock in the box.

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 offer enhanced functionality in drilling operations.

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.

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.

RetroLOCK™ Overshot Assemblies & Options
The RetroLOCK Overshot is a simple, self-locking, compatible solution to retrieving the Inner Tube Assembly efficiently and reliably. The RetroLOCK latching system is 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.

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 and Screws, as well as Lifting Dogs. The Pump-In Overshot spares kits contain the same items, less the EdgeLOCK components.
