Core Barrel Assemblies & Options

EdgeLATCH is Di-Corp’s specialized latching system used in core barrel head assemblies for drilling operations. What sets it apart is its innovative mechanical design and compatibility with a wide range of core barrel assemblies.

Its key features include:

• Reliable latch retraction: EdgeLATCH transfers pulling force from the latch retraction case through a pin to the latches, ensuring consistent and dependable operation.
• Versatile compatibility: The system supports both tanged and non-tanged locking couplings through its integrated latch spring and independent latch movement.
• Improved durability: EdgeLATCH helps protect against contamination, extends bearing life, and enhances impact resistance, ideal for demanding drilling conditions.
• Efficient inner tube retrieval: Its mechanical advantage during unlatching makes it easier to release inner tubes, especially when they’re difficult to remove.
• User-friendly design: Standard with a landing indication, the EdgeLATCH system is easy to use and install across various drilling scenarios.

Overall, EdgeLATCH delivers enhanced reliability, safety, and efficiency, making it a practical upgrade for drilling professionals seeking better performance in the field.

RetroLATCH is Di-Corp’s core barrel head assembly latching system used in diamond core drilling, particularly for mineral exploration. It plays a critical role in securely retrieving core samples from deep underground.

Here’s what it does and why it matters:

• Function: RetroLATCH is part of the in-hole tooling system that locks the inner tube (which holds the core sample) in place during drilling and helps retrieve it once the drilling run is complete.
• Compatibility: It’s based on a widely adopted latching design that works with most standard core barrel assemblies used in the field today.
• Performance: It provides consistent pressure indication and a secure core landing, which improves drilling efficiency and reduces the risk of lost or damaged core samples.
• Durability: With high-quality components, such as spindle bearings and robust shut-off valves, RetroLATCH is engineered to minimize failures and withstand demanding conditions.

In short, RetroLATCH helps ensure your core retrieval process is efficient, secure, and dependable, even in tough drilling environments.

EdgeLATCH and RetroLATCH are both reliable core barrel head assembly latching systems from Di-Corp, but they’re built for different drilling needs.

EdgeLATCH features an enhanced latch retraction mechanism that helps reduce the risk of stuck inner tubes, making it ideal for challenging ground conditions or deeper holes where retrieval issues are more common.

RetroLATCH, on the other hand, is based on the industry’s most widely used latching system. It offers proven reliability, consistent pressure indication, and broad compatibility with existing core barrel assemblies, perfect for mineral exploration programs using standard tooling setups.
