Frequently Asked Questions

What are the main advantages of the QL60 DTH Hammer?

The QL60 is a valve-less hammer designed for high energy output and durability. It features a robust design that works efficiently even at low air pressures and includes heat-treated internal components for a longer lifespan.

Which industries typically use these drilling tools?

These hammers are widely used in open-pit mining, quarrying, water well drilling, foundation anchoring, and road construction for drilling and blasting.

Does the QL60 hammer require a foot valve?

No, the bits for the QL60 and the DHD/QL/MISSION series are designed without a foot valve, making them more robust for heavy-duty applications.

What is the recommended working pressure for the QL60?

The standard working pressure for the QL60 DTH hammer ranges between 10 to 25 Bar, depending on the specific drilling requirements.

What hole diameters can be achieved with the 6-inch series?

The 6-inch series, which includes the QL60, typically covers a hole range from Φ155mm to Φ190mm.

Are the internal components replaceable or reversible?

While components are built for longevity, please note that the wear sleeve for this specific series is not reversible. All critical internal parts undergo strict heat treatment to ensure reliability.
