We've improved the traditional Core Barrel and Overshot designs with an innovative approach that increases the safety and reliability of latching and locking. Our Edge series features the EdgeLOCK'™ Overshot Assembly.
Safely and efficiently retrieve your inner tube assembly or core sample with our overshot systems. Whether you need a full assembly, head assembly, or spares, MUD MASTER has your overshot needs covered with options compatible with commonly-used coring systems. Maximize core retrieval with our effective and safe overshot options. Safety is first with MUD MASTER's EdgeLOCK Overshot locking system. The EdgeLOCK Overshot is a simple, self-locking, compatible solution to retrieve the Inner Tube Assembly efficiently and reliably. With the unique edge lock remember to stop and engage a safety mechanism, gravity automatically does it for you! The EdgeLOCK Overshot eliminates the need to manually lock in the head - keeping your fingers out of harm's way in the process. As soon as you start to raise the overshot, the weight of the head pulls the lifting dogs into the locked position. The head remains "locked in" until the weight is removed, and you manually compress the lifting dogs to release. EdgeLOCK Overshot Assemblies are offered for B, BU, N, N2, N3, H, H3, and HU sizes.
If you're looking for a traditional "swing-out" link-style latching system, try RetroLATCH — it's a blast from the past, but it gets the job done! Additionally, the MUD MASTER RetroLATCH head assembly design is fully compatible with that of manufacturers.
RetroLATCH Core Barrel Assemblies are offered in H and N sizes.
The Rolling EdgeLOCK Overshot is a modified version of the standard EdgeLOCK Overshot. It features a unique edge lock mechanism that 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.
Rolling EdgeLOCK Overshot Assemblies are offered for B, N, N2, N3, H, and H3 sizes.
