Product Detail
Quantum Leap (QL) DTH Hammer
Introduction:
Our Quantum Leap product line is available for those seeking a good balance between strong performance and cost. This product line was the industry's first hybrid-combination of valve and valve less air cycled down-hole drills. Setting many industry benchmarks, the Quantum Leap line continues to offer good value.

Secoroc QLX 50/55 down-the-hole hammers
QLX – the latest in high performance DTH hammers
At Atlas Copco Secoroc, we keep looking for new ways of improving our customer’s productivity.
That’s why we have taken the best of the QL design, thrown in a few new ideas and created the Secoroc QLX 50 and QLX 55 down-the-hole hammers.
QLX 50 and QLX 55 are primarily deep hole hammers, but also proven to be high performance hammers for other applications.
These new 5" hammers offers 20% more all round performance than the QL hammers and better water-logged deep hole drilling capacity than it´s predecessor, the TD 50 hammer. They are benchmarks with highest rate of penetration (ROP), and reliability that are a cut above the rest, thanks to solutions such as the new e-kit making servicing easier and quicker to execute.
The QLX 55 has thicker heavy duty (HD) casing for longer service life when drilling in abrasive rock formations.
The QLX 50 and QLX 55 has been stringently field tested in USA and Sweden prior to launch.
They have proven outstanding in water well, geothermal drilling and other applications, thanks to the Air select feature that enables the QLX to match a variety of air packages while utilizing the excess air for hammer power.

Selecting the right hammer
The optimum range of hole size for blast hole drilling with DTH is 90 mm to 254 mm (3 ½"–10"). Smaller blast holes are generally drilled using tophammer, and larger holes generally use rotary machines.
In other applications, like foundation drilling, DTH hammers can be used with single bit in hole sizes up to 914 mm (36"). With multiple hammer units CD (Cluster Drills) drill holes up to 70" or 1778 mm as standard.
Larger cluster drills can be delivered as per customer request.
As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. A 4 inch hammer will drill a 4 inch (102 mm) hole. The limiting factor is the outside diameter of the hammer, because, as hole
diameter reduces, airflow is restricted. Maximum hole size for production drilling is the nominal hammer size plus 1 inch, so for a 4 inch hammer the maximum hole size is 5 inch (127–130 mm).
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.
Secoroc hammers are purpose-matched for all rock types and applications. Where high performance is the main criterion, Secoroc COP Gold hammers are recommended in blast hole drilling and Secoroc QLX hammers in deep hole drilling applications. The QLX hammer has proven superior performance and adaptability to different air requirements thanks to the Air Select System.
Where proven technology is required, the Secoroc COP and QL hammers are known for their reliability and longevity. They are practically bullet proof, making them useful for production drilling in quarries, shallow water well drilling, and underground blasthole drilling.
QM is similar to Standard, but with heavy duty chuck and wear sleeve, and a top sub fitted with tungsten carbide buttons for wear protection in harsh and abrasive conditions. These also protect the top sub from excessive wear when rotating out of the hole through broken Rock.
Service and support
Atlas Copco Secoroc service, support and training follows every purchase, to ensure that customers extract maximum productivity from their drilling operations. Having a knowledgeable and available Secoroc drilling partner on site or online makes the difference between going it alone and tapPing
the experience and know-how of a world-class partner.
For example, Secoroc knows that using higher productivity bits reduces the cost of each drilled hole, and the simplest way to cut costs is to drill holes faster. This has been a focus of product development, and is at the core of Secoroc technology, ensuring that every generation of products drills faster and more efficiently.
It takes a support team to apply this knowledge, so that customers can be assured they run a profitable and efficient drilling operation in an increasingly competitive business climate.
The bottom line is that the customer can count on Secoroc service and support, supplied by the largest, most dedicated manufacturer of DTH drilling tools in the world.
