Technology that Works




Matching DTH hammer air consumption to compressor delivery can be difficult and prone to guesswork. With the patented AIRselect system the process is both simple and efficient. Unlike bypass plugs or chokes, this proprietary Atlas Copco system does not rob penetration rate as air compression is increased.


COP Gold hammers



COP Gold Wear Resistant Technology


COP Gold hammers use a special high strength steel specially developed for rock drilling applications, which means it stands up to abrasion.


You can even wear it down below recommended wear limits and it still will not crack.


All in all, you can look forward to a 30-50% longer service life compared to many competitors' models.






Non-Lube DTH Hammer



Non-Lube DTH hammers deliver long life and high performance without needing the oil or polymers normally required for lubrication. Non-Lube technology also addresses environmental concerns relating to the use of oil. Advanced sealing technology compensates for wear and maintains high performance after many external rebuilds.

Cluster Drills


Cluster Drills


Atlas Copco offers a hard rock drilling system capable of drilling 32 to 70 inch diameter holes by combining multiple down-hole drills into a single canister.

These drills are custom engineered and manufactured to meet each customer's unique hole size requirements. The drills are short, lightweight, and compact, featuring exclusive, patented technology for self-indexing and quick-release bits.

The bottom line: Servicing is infrequent and unusually efficient.





Fluids need to be injected to clean a drilled hole, and until Hydrocyclone technology drilling speeds were compromised as fluids were injected. Atlas Copco's exclusive, patented system expels injected fluids just above the down-hole drill. The result?

As much fluid as necessary can be injected without concern for loss of performance. The hole stays clean, and the hammer runs as if it was operating dry.


Utility Power Pole Drill


Utility Power Pole Drill


When compared to augering or blasting methods, Atlas Copco's utility pole drill permits electric pole sockets to be drilled in hard rock much more efficiently. When coupled with a portable compressor and a pole installation truck, the result is rapid creation of multiple utility pole holes.


Jet Sub


Jet Sub


Atlas Copco's Jetted Total Depth backhead prevents the power losses normally associated with air bypass.

The upward facing ventures on the backhead allow extremely high volumes of bypass flow to escape behind the DTH hammer to enhance performance and hole cleaning capacity without the use of booster compressors.



Bit Retrieval System

Bit Retrieval System


Oil and Gas drilling contractors and owner-operators understand that everything down-hole must be extremely reliable. Bit failures occurring deep in a well bore are very costly.

In some extreme cases a bore must be abandoned if a broken bit cannot be recovered, and this can cost tens of thousands of dollars. Atlas Copco's Bit Retrieval System reduces this risk by providing a secondary means for securing a bit head to a down-hole drill to both facilitate and guarantee recovery.

Atlas Copco's Specially Formulated Oils

Built on a foundation that includes many years of design experience and material technology, all Atlas Copco bits are comprised of high quality alloy steel, precision machining, controlled heat treatment, surface compression for fatigue resistance, and high quality precision fitted buttons from our own in-house manufacturing.

The bottom line is you get a high quality product with optimum productivity time after time from a brand you can trust.



Drill Pipe


Though their importance is often underestimated, pipes play an important role in DTH drilling--regardless of application, rock type, hole depth, or drill rig. The key feathers of a high quality DTH pipe are durability, accuracy, and manageability.


Drill PipeSecoroc pipes are made from cold drawn tubing, providing a superior surface finish and tolerance compared to their hot-rolled counterparts. Our solution drastically reduces the risk of scaling--the cause of so many premature hammer failures.


Traditionally, the threads and the joint between the pipe and end-pieces are vulnerable. To combat the problem we've friction-welded the joints for maximum strength and heat-treated the end-pieces for optimum the threads ensures not only a long service life, but also simplifies joining and breaking--thereby cutting cycle time. To meet varying demands, we provide a selection of API threads. For applications where foam injection is used we recommend IF thread. Atlas Copco also offers all of the other popular thread configurations: BECO, Full Hole (FH), and "Z". Naturally, we also offer a wide range of subs and crossovers--all made of high quality steel and heat-treated in the same way as pipe end-pieces.


Sub Adapters
