Leading Couplings/Adapters

in China

Coupling is used for connecting shank adapter and extension drill rod together, or for connecting two extension rods together. Besides normal equal couplings, we also offer reducing couplings that are able for changing thread type and size.

What Are Used For?

A coupler is a very short pipe or tube that has a socket at one (or both) ends. This allows two pipes or tubes to be joined (or coupled), welded or soldered together. An adapter is used to convert the attributes of one device to another.

How does work?

Top hammer Couplings adapters

Top hammer Couplings adapters are engineered to withstand extreme stress. They transmit impact energy from the rock-drill piston and rotation torque into the drill string without energy loss.


Threaded button bits use a proprietary grade of cemented carbide throughout and range from 28 – 152 mm in diameter. Various button shapes (spherical, semi-ballistic, and conical) and skirt designs (regular or retrac) deliver optimal performance in different rock formations.

Key advantages of Top Hammer drilling include: Speed and Efficiency: Top Hammer drilling excels in surface drilling applications, offering higher drilling speeds and efficiency for shallower holes.
