How to use tapered rod accurately
Tapered rod should ensure that there is only enough mating surface with the tapered button bit. In general, the depth of the tapered drill rod inserted into the tapered button bit should be ≥26mm. Therefore, try to use tapered rods whose taper tips are machined by machining. The drill rod used in conjunction with the tapered button bit should be straight to the naked eye, and the impact end face of the drill tail should be flat. Whether it is a tapered bit or a tapered drill rod, the water hole should be kept clear.
