What Are Wireline Stop Rings?
A wireline stop ring, also known as a centre spear, is a hardened steel snap ring designed to seat into a mating groove. Its primary function is to retain the core lifter in the core lifter case. These rings are commonly used in standard DCDMA N, H, and P sizes.

Features and Benefits:
Retention of Core Lifter: The stop ring securely holds the core lifter in place, preventing accidental dislodging during drilling. This ensures consistent core recovery.
Efficient Penetration: The prong ends of the centre spear increase in outer diameter until just below the diameter of the stop ring. This design allows efficient penetration into tight balls of broken wire.
Customization: Wireline stop rings come in various styles, outer diameters, and thread connections. Users can choose the combination that best suits their drilling needs.
Conclusion:
Wireline stop rings play a critical role in maintaining drilling efficiency and core sample integrity. Whether you’re exploring mineral deposits or conducting geotechnical investigations, these rings ensure reliable core lifter retention.
