Drilling tools
A range of tools and accessories designed to optimize drilling operations in every soil condition. Combining advanced hydraulic systems, field expertise, and innovative engineering, these tools ensure precision, efficiency, and reliability on even the most challenging construction sites.
BUCKETS
Buckets are ideal for drilling soil and rock layers in water-rich environments or when using bentonite-based drilling techniques.
Buckets feature a rotating bottom for material loading and a vent pipe to reduce water or bentonite pressure, ensuring easy lifting. Equipped with a mechanical opening system for quick material release, they can be customized with various teeth and chisels depending on soil and rock hardness.
Casagrande buckets are fully compatible with screw and labyrinth-type casings and can be tailored to specific client needs.
Designed for fine-grained soils and bored piles up to 1000 mm, especially effective with casings and coarse gravel.
Best suited for fine-grained soils and bored piles over 1000 mm, ideal for secant pile walls
AUGERS
Casagrande offers a wide range of augers for drilling dry soil and rock layers, designed to accommodate various pile diameters.
All augers feature durable central pipes and flights tailored to handle XP rotary torque and gravel strength. They include HB 600/900 wear protection and can be customized with different teeth and chisels based on soil and rock hardness, ensuring high productivity through advanced design software.
Casagrande augers are compatible with screw and labyrinth-type casings and can be modified to meet specific client requirements.
Ideal for drilling in water-rich soils and rock layers up to 1000 mm, especially with casing applications.
Best for rock layers and bored piles exceeding 1000 mm in diameter.
Perfect for very hard rock formations, with a spiral flight design for progressive and efficient cutting.
CORE BARRELS
Core barrel is used for cutting annular ring in rock, concrete and in steel reinforced concrete; consequentially the centre core can be broken using chisel, rock auger or Cross Core Barrel.
Using core barrel is possible to increase considerably pressure and torque on the cutting ring which can be equipped with different type of round shank chisel, quick change bars and roller bits.
Core Barrel diameters match perfectly Casagrande casings in both alternatives: Screw and Labyrinth types.
Their dimensions can be changed on Client needs and they are available on request.

CASING
Casagrande produces a range of casing joints and pipes designed to protect piles from collapse during drilling. These components facilitate easy pipe connections and include two main coupling systems: conical screw joints and labyrinth joints.
Terminal Sections: Casings are fitted with cutting rings that include widia inserts or other cutting materials.
•Casing Drivers (Twisters): Used for driving casing directly via the base rig’s rotary table or for assisting in pipe section coupling during oscillator operations.
Casagrande’s casing joints ensure durability, efficiency, and adaptability for challenging soil conditions and project requirements.
- Suitable for both double and single wall casings.
- Made of high-quality steel, designed for heavy-duty applications.
- Available for diameters ranging from 600 mm to 2500 mm (custom sizes available).
- Joint thickness varies between 40-70 mm based on casing diameter and soil conditions.
- Ideal for use with casing oscillators and rotary systems.
- Coupling is achieved through conical thread screws and centering keys for fast assembly.
- Designed for quick coupling of double and single wall casings.
- Available for diameters from 600 mm to 2500 mm (custom sizes available).
- Joint thickness varies between 30-70 mm depending on diameter and soil features.
- Coupling uses inserts in the female joint recesses, designed to support columns during pipe extraction.
TREMIE PIPES
Tremie pipes are essential for pouring concrete into drilled piles after placing the steel cage reinforcement. They ensure the integrity of the concrete by preventing contamination from soil or water infiltration, avoiding quality issues or gaps in the pile.
Casagrande tremie pipes are made of high-quality steel plates to ensure durability and resistance. They come with two coupling systems for connecting pipe sections: threaded joints and wire cable joints.
Casagrande tremie pipes and accessories provide a reliable solution for precise, uncontaminated concrete placement, meeting the demands of various piling projects.
Equipped with male/female threaded connections for secure assembly.
Designed for quick assembly and disassembly during concreting operations. These joints feature OR ring seals to prevent water and mud penetration.
- Funnel: For directing concrete into the tremie pipe.
- Lifting Swivel: Facilitates lifting and lowering of the pipe.
- Chain Spanner: For tightening and unscrewing threaded joints.
- Fork Spanner: For the wire release system.
- Anti-Slip Platform: Equipped with a clamping system to prevent pipes from falling into the holes.
- Container Rack: For convenient pipe storage and transportation between job sites.
CFA
Continuous Flight Auger (CFA) piles are a reliable drilled foundation technique. The pile is drilled to its final depth in a single continuous process using a continuous flight auger. Concrete is pumped under pressure through the hollow stem of the auger to the bottom of the bore, and as pumping progresses, the auger is gradually withdrawn, bringing the excavated soil to the surface. Once the auger is removed, reinforcement is placed into the concrete pile to meet design specifications.
- Installed with minimal vibration and noise.
- Efficient for a range of soil conditions.
Casagrande offers two types of CFA couplings, 160 mm and 200 mm, tailored to rotary torque, soil conditions, and drilling depth requirements. CFA strings come with inner tube diameters of 5” and 6” for compatibility with base rig concrete piping, with other sizes available on request.
Casagrande CFA solutions are designed for high performance, offering customization to meet specific project demands while ensuring efficiency and reliability.
High-strength hexagonal male/female joints, fully machined from case-hardened steel.
- Double-start head for rock or soil.
- Equipped with interchangeable round shank chisels or teeth.
Bottom exit includes a steel plug and recovery chain; side exit available on request.
FDP
Soil Displacement piles are cast-in-situ concrete piles constructed using a rotary drilling rig, which advances a displacement boring tool into the ground by applying torque and crowd force. This method is ideal for various soil conditions, including sandy gravel, sand, silt, clay, and soft organic soils, as long as the soil can be displaced.
During concreting, the full displacement auger continues to rotate clockwise as it is extracted, with tangential reamers creating spiral grooves along the borehole walls. These grooves are filled with pressurized concrete, significantly enhancing the pile’s load-carrying capacity.
- Diameter Range: Piles can be constructed with diameters from 250 to 1000 mm.
- Inclination Ratio: Up to 4:1 under normal conditions.
- Torque Transfer: Casagrande joints handle torque moments up to 600 kNm.
Casagrande’s Full Displacement Augers are designed for cost-effective, environmentally friendly, and safe production of vibration-free cast-in-situ concrete piles. They offer high performance and reliability for projects requiring ground stability and environmental consideration.
Simplified technology eliminates the need for temporary casings.
The full displacement auger compacts the soil as it is screwed into the ground with its lower opening sealed by a bottom plate.
No excavation takes place, keeping boreholes dry.
Suitable for projects near sensitive structures, groundwater tables, or contaminated soils where soil exchange is not possible.
The walls remain supported at all times, eliminating the risk of collapse.
