Drill hammer end coupling
Drill hammer coupling (Drill Bit Coupling or Drill Chuck Coupling) is a mechanical part that connects the drill hammer (hammer) to the drill bit or drilling bit.
The main functions of the drill hammer end coupling:
Transfer of force and torque: The coupling transmits the hammer’s impact force and rotational force from the hammer to the drill bit to enable drilling into the ground.
Stability and precise alignment: This coupling ensures the drill bit is securely and accurately connected to the end of the hammer, minimizing unwanted movements or looseness.
Vibration and damage reduction: The proper design of the coupling helps control the transmission of vibrations and pressures from the hammer blows to the drill bit, which increases the service life of both the bit and the hammer.
Quick replacement capability: The coupling is designed so that the drill bit can be replaced quickly and easily, ensuring high drilling productivity.
Precise manufacturing and machining of drill bit couplings (nut) in various sizes.
