Down-the-hole hammers

Secoroc hammers are purpose-matched for all rock types and applications. Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.

Down-the-hole pipes and adapters

High quality for high performance.

Key features of a high quality DTH pipe are durability, accuracy and manageability. Atlas Copco Secoroc pipes are made from cold drawn piping, providing a superior surface finish and tolerance compared to conventional pipes made from hot rolled piping.

  • Our pipes meet the highest requirements when it comes to durability and productivity.

Reverse circulation

Atlas Copco Secoroc's reverse circulation hammers are specifically designed for all kinds of exploration drilling (deep hole and in-pit grade control applications). Whether you are exploring potential sites or working an existing mine, the Secoroc RC hammer will guarantee high performance, exceptional reliability and dependable support.

  • RC hammers are essentially the same as conventional DTH hammers, but with an inner-tube that runs through the centre of the entire hammer.
  • The cuttings are collected in the holes in the front of the bit and confined and transported in the inner-tube.
  • The flushing is in-between the splines of the bit and the chuck.
  • The inner-tube is a wearing component and is replaced easily through the top of the hammer.
  • In all Atlas Copco Secoroc RC hammers the inner-tube assembly can be removed without removing the backhead.

Secoroc COP RC45

Smaller, lighter, faster.


The Secoroc COP RC45 reverse circulation hammer features a revolutionary new design. It's 40 % shorter than the nearest competitor. And shorter means less weight. The COP RC45 is more than 30 % lighter than most hammers doing the same job.

The COP RC45 has a unique air chamber design. Much smaller chambers build up pressure faster and makes the piston strike at a much faster rate. The result is marginally lower impact energy and leads to a great increase in power output and a sizeable improvement in penetration rate.

The COP RC45 features Secoroc's unique tube retention system. This design makes it easy to service and replace tubes since you don't have to disassemble the hammer. Quite simply this means minimum down-time and maximum time producing samples.

  • Working pressure: 10–35 bar
  • Air consumption: 534 l/s (1131 scfm)
  • Piston weight: 10,4 kg
  • Frequency: 3360 strokes/min
  • Hole size: 127–140 mm (5.5")

Breakout bench

Handy but powerful.

The threaded connections of the driver chuck and the top sub may become very tightly tensioned during drilling. It is convenient to break the hammer threads on the rig, but if the threads cannot be loosened or tend to get stuck, a breakout bench is the solution. This handy but powerful breakout bench can easily be placed in a workshop or container and it breaks DTH hammers between 3 – 8" in the standard version or 5 – 12" in the heavy duty version.
