Moreover, the use of extension rods improves the stability of the drill string. As the distance from the drilling machine to the drill bit increases, so does the potential for vibration and instability, which can lead to deviations from the intended path or even damage to the drill bit As the distance from the drilling machine to the drill bit increases, so does the potential for vibration and instability, which can lead to deviations from the intended path or even damage to the drill bit As the distance from the drilling machine to the drill bit increases, so does the potential for vibration and instability, which can lead to deviations from the intended path or even damage to the drill bit As the distance from the drilling machine to the drill bit increases, so does the potential for vibration and instability, which can lead to deviations from the intended path or even damage to the drill bitcore drill bit extension rod. High-quality extension rods are designed to minimize these risks by ensuring a tight fit with the drill bit and by being rotationally stable, thus reducing the chance of twisting or bending that could compromise the integrity of the drill hole.
