The 76B single core barrel belongs to Technidrill’s B range of single core barrels. This core barrel is designed for drilling in homogeneous formations. It does not include an inner tube, which lightens the assembly and simplifies use. As a result, the 76B single core barrel supports high coring rates and a smoother site workflow. It is aimed primarily at geotechnical teams seeking to optimize cost and time per drilled meter. Thanks to its simple design, this core barrel integrates easily into an existing fleet. Finally, the lighter logistics make transport and setup easier.

Why choose this conventional core barrel?

The 76B single core barrel is a smart choice when execution speed is the priority. In this context, the single core barrel helps reduce stoppages and limit maintenance. It also offers excellent handling on shallow drilling. In addition, it remains relevant for high-volume coring programs where every minute counts. In short, this core barrel is a robust and economical solution for routine soil investigations in homogeneous ground.

Key advantages of 76b single core barrel

• Lower cost per meter: the 76B single core barrel has fewer parts and no inner tube, which reduces consumable spend.
• Higher penetration rate: the bit’s low cutting surface promotes faster, more regular progress, leading to steadier daily productivity.
• Simplified maintenance: with fewer mechanical components to monitor, you save workshop time and reduce downtime.
• Easier handling: a lighter, more manageable setup helps crews on repetitive, shallow operations.
• Custom configuration: core barrel heads are offered separately, so you can tailor the tool to your exact job requirements.

Technical specifications – 76B single core barrel

The 76B is a single core barrel with a 76 mm diameter. This size covers a broad range of geotechnical coring in homogeneous formations.

• Model diameter: 76 mm
• Other diameters in the B range: 46, 56, 66, 86, 101, 116, 131, and 146 mm. These options help you align your core barrel fleet to each project. Discover the full B range: https://technidrill.com/en/geotechnics/
• Available lengths: 500 mm, 1,000 mm, 1,500 mm, and 3,000 mm. Choose the core barrel length that balances rate, depth, and handling.
• Core barrel heads: sold separately to facilitate maintenance and specific configurations without immobilizing the entire barrel.

Limitations of use

The 76B conventional core barrel is intended only for homogeneous formations. In heterogeneous soils, the core is not supported by an inner tube and may deteriorate during extraction. In such conditions, the use of this core barrel is not recommended. It is advisable to select a core barrel designed to hold the core in mixed ground. This prevents rework and protects sample quality.
