Conventional augers are at the core of geotechnical and environmental drilling operations. This type of equipment is designed to extract soft or semi-compact soils while ensuring excellent hole stability. Augers are essential for sampling campaigns, reconnaissance drilling, and soil investigations.
Technidrill offers a complete range of conventional augers in HEX 41 and HEX 50, known for their robustness, machining precision, and compatibility with a wide variety of drilling tools and accessories.
1. Conventional augers: design and key features
A conventional auger consists of a hollow tube fitted with a helical flight designed to lift soil to the surface. The HEX 41 and HEX 50 models stand out for their hexagonal thread, ensuring a high torque transmission and a rigid connection between rods.
These augers are available in diameters ranging from 100 mm to 200 mm and lengths from 1,000 mm to 3,000 mm, making them adaptable to any ground conditions thanks to their wide range of configurations.

Advantages of HEX 41 and HEX 50 Conventional augers:
- Optimized torque transmission with hexagonal coupling.
- High-strength steel construction for long-lasting durability.
- Full modularity with Technidrill drilling tools.
- Compatibility with multiple head and accessory systems.
Thanks to these features, Technidrill’s conventional augers stand as a reliable solution for drilling sites requiring power, stability, and precision.
2. Technidrill auger bits: adapted to all soil types
Choosing the right auger bit depends mainly on the type of formation encountered. Technidrill offers a wide range of bits designed to suit every geological condition — from soft soils to hard rock.
2.1. Fish tail blades
Ideal for sandy or loose formations, Fish Tail Blades provide rapid penetration and efficient material removal. Available in diameters ranging from 64 mm to 254 mm, they are compatible with HEX 21 to HEX 51 systems.
2.2. Mining bits and finger Bits
For harder formations, Mining Bits and Finger Bits deliver aggressive cutting performance and increased wear resistance. Offered in multiple sizes — including HEX 29 to HEX 41 — they ensure perfect alignment with the auger diameter and soil conditions.
Finger Bits are particularly effective in semi-rocky terrains, combining robustness with ease of maintenance thanks to their interchangeable fingers.
2.3. Bulldog and DP Rock bits
For very hard and abrasive formations, Technidrill provides Bulldog and DP Rock bits:
- Bulldog Bits are designed for abrasive terrains, offering superior durability due to their reinforced design.
- DP Rock Bits feature hardened steel teeth, ensuring maximum penetration into compact rock.
Each bit can be paired with specific accessories, such as replacement fingers, for easy and cost-effective maintenance.
3. Conventional auger accessories: performance and safety on-site
Technidrill’s full range of auger accessories ensures secure assembly, smooth handling, and efficient torque transmission throughout drilling operations.
3.1. U Pins
U Pins (HEX) securely connect individual auger sections. Available for HEX 21, 29, 41, and 51, they allow fast and strong coupling between rods during assembly or disassembly.
3.2. Universal joints
Universal joints help transfer rotation and compensate for minor misalignments between the drilling head and auger. Technidrill offers several models compatible with standard connections — 2″3/8 IF, REG, R66, H41, H55, H64, and more — ensuring both flexibility and safety.
3.3. Auger holders and auger retrievers
Auger holders are used to maintain the auger in position during lifting operations, while auger retrievers allow recovery of tools left at the bottom of the borehole — a must-have accessory on the field.
4. French manufacturing conventional augers
Based in Carros (Alpes-Maritimes), Technidrill designs and manufactures its products in France, using high-quality European materials. Each auger component is machined with millimetric precision to guarantee reliability and performance even on the most demanding worksites.
The Technidrill HEX 41 and HEX 50 conventional augers strike the perfect balance between strength, efficiency, and versatility. Designed to meet professional drilling requirements, they integrate seamlessly into a complete system that includes specialized bits and high-quality accessories.
Whether you’re working on soft ground or rocky formations, Technidrill provides high-performance, durable solutions to optimize your drilling operations.
