QLX 50/55 - The Latest in High Performance DTH Hammers

Secoroc QLX 50/55 hammer at Roschen and Atlas Copco Secoroc, we keep looking for new ways of improving our customers' 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 have also proven to be high performance hammers for other applications.

These new 5" hammers offer 20% more all-around performance than the QL hammers and better water-logged deep hole drilling capacity than its predecessor, the TD 50 hammer. They are benchmarks with the 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 have been stringently field tested in the 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.
