Focus on consumables

All of the Robit® button bits are manufactured of new 100% recyclable steel. In the environmentally friendly steel production process the CO² emissions have been reduced 80% and 95% of the waste is recycled including the process smoke which is filtered. The new steel grade gives even more uniform properties and improved fatigue strength which is crucial in rock drilling process. Designed for particular applications from soft rock formations to extremely hard conditions.

Models:
• A – medium and hard rock model
• M – soft and medium hard rock model
• S, SR – all around model
• Se – evolution model for high power and frequency drilling
• FF, FFR – Flat Face for medium and hard rock conditions
• FF HD, FFR HD – Flat Face Heavy Duty model for more abrasive conditions
• DC, DCR – Drop Center model for straighter holes with maximum flushing properties
(for soft and medium hard rock for speed drilling)
• DC HD, DCR HD – Drop Center Heavy Duty model for more abrasive conditions

Designed for fast and straight drilling of cut holes
• Dome reamers where integrated pilot with reamer
• Composed of pilot adapter or chicel and reaming bit

Produced from the carefully selected hollow drill steels, drill rods provide the advantages of the maximum strength with long thread life.
• Hexagonal Drifter Rods, Single & Tandem Thread Rods, Male-Female Rods
• Available with most types of threads

With specially developed alloys, shanks are with optimum hardenability and balance of core and case properties to offer extended wear and fatigue life.
• Compatible with most types of drills in the market

Produced for optimum energy transfer on various drilling diameter.
• Coupling Sleeve, Coupling Adapter, Bit Adapter
• Available with semi-bridge or full-bridge

Single-use system for top hammer

Robit® Single Casing Systems are available for traditional top hammer machinery.

Typically Robit® Single-Use system for Top Hammer is used in applications with relatively short hole requirement and where the casing is left in the ground.

Prime system for down the hole hammer

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.

• Suitable for different wall thicknesses, easy to align and weld
• Available with Flow Control rinsing
• With the Drill Through pilot bit, rock sockets can be drilled in a single work phase

Solitary ring system for down the hole hammer

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.
