How To Use QL60 Down Hole Hammer Bits?
Down hole hammer bits, also known as DTH hammer bits, are drilling tools for mining,?construction, and oil and gas industries for drilling through rock. And DTH bits have many types according to their design and purpose for specific geological conditions and drilling requirements.
For example,there are DHD3.5, DHD360,DHD380, QL40, QL50, QL60, M60, M80,etc. What’s more, it has Various designs including convex, concave, flat face.
What is QL60 Down Hole Hammer Bits?
Definition
Several well-known drilling equipment manufacturers launched the QL60,?including Atlas Copco (now Epiroc) and Sandvik. The "QL" stands for "Quantum Leap", which?indicating the improvement in technology and performance of this series of hammers.?The QL60 hammer and bit are suitable for medium to large drilling projects and perform well in hard rock.

How to use
Preparation
First, inspect the DTH hammer and QL60 drill bit to ensure there is no wear or damage. And verify that all connecting parts, such as joints and seals, are in good condition. Then, make sure the air compressor has the pressure and flow required by the QL60 impactor. Typically the max. working pressure is 3.0Mpa, and air consumption is 20m3/min at 18 bar. Finally, operators should wear appropriate personal protective equipment such as hard hats, goggles, gloves and shoes.

Drill bit installation
First, install the QL60 drill bit securely into the bottom of the hammer. In the mean time, use the appropriate tools and torque to ensure the connection is secure. After that, connect the drill rod with the drill bit and hammer installed to the drilling rig.
?
After that, start the air compressor and start drilling. During the drilling process, continuously monitor the working status of the drill bit and the drilling situation. Adjust the drilling parameters such as speed, pressure and impact frequency in time according to geological changes.
