Reaming Shells
Reaming Shells – Precision Borehole Stabilizers for Core Drilling
Engineered Diamond Reaming Shells for Maintaining Borehole Gauge and Bit Alignment
Ideal for Wireline Core Drilling, Mineral Exploration, and Geotechnical Borehole Support
✅ Product Overview:
Reaming Shells are a crucial component in core drilling systems, positioned directly behind the core bit to maintain hole diameter, stabilize the drill string, and extend the life of core bits. These durable shells are embedded with natural or synthetic diamonds and designed to ream the hole to gauge, especially in abrasive or fractured formations.
Reaming shells help prevent deviation, reduce wear on drill rods and bits, and ensure smooth core barrel operation—making them indispensable for mineral exploration, geotechnical sampling, and deep borehole drilling.
