Robit® Prime ring bit product family makes it possible to pile both welded and threaded casing tubes using the same ring bit. Pile walls can also be made using the XL2 ring bit. With the Drill Through (DT) model, drilling can be continued with just the pilot.
Robit’s Nova system is tailored for overburden rich in boulders. Designed for seamless integration with common down-the-hole hammers, this innovation ensures swift, reliable drilling in all conditions, while uniquely catering to applications where casing is left in the ground. Its versatility extends to water wells and thermal wells, making it the go-to solution for efficient and precise drilling in diverse geological landscapes.
In some overburden drilling applications the casing has to be removed from the ground. This sets higher requirements on the durability of the equipment. Double groove design* in the casing shoe and the best materials available guarantee that Robit Multi-Use System does not fail, even in the most difficult conditions. Robit Multi-Use System is available for all the common DTH hammers.
Sometimes overburden is thick and full of boulders. Robit Single-Use Casing Systems for DTH Hammer enables easy, fast, and reliable drilling process in all conditions. Robit Single-Use Casing Systems are available for all common Down the Hole Hammers and are designed for all the applications where the casing is left in the ground.
Robit® concentric CDS-RS overburden drilling system range has been designed to allow continuous casing of a hole, through loose overburden material, down to and into solid bedrock . Using Robit’s patented Airflow system, the CDS-RS’s venturi effect vacuums cuttings away from the front of the drill bit and diverts the exhaust air back up the hole, greatly reducing the volume of air that would otherwise pass into the ground where it could cause potential problems.
Robit has developed a system for fiberglass casings. A unique casing shoe works as a shock-absorber protecting the drilling forces. Fiberglass casings bring several benefits.
Robit Steel Fist product family is designed for specific piling operations, sizes from 273 mm up to 1200 mm. New economic way for traditional piling work, but also capable for installing water-proof Pipe-Pile-Walls. No ring bit is needed when piling with DTH SF. Usage in homogenous soil conditions with small boulders. Robit Steel Fist Casing Systems are available for all the common Down The Hole hammers and can be used for all applications where the casing is left in the ground but have been especially designed for:
DTH SR products are economical and cost-effective to use when the ground is homogenous with few small boulders. With the same pilot you can install piles and interlocked Pipe-Pile-Wall piles just by using ring bits with different outside diameters. Robit Solitary Ring Casing Systems are available for all the common Down The Hole hammers and can be used for all applications where the casing is left in the ground but have been especially designed for:
The new Robit® DTH-REC system is specially designed to offer a maximum reliability in overburden drilling conditions.
