2. The selection of hole diameter and depth. Due to its own rotational speed and cutting properties, when selecting a hole saw drill bit, it is important to pay attention to selecting a hole size that is suitable for oneself. The hole depth should be determined based on one's own material. In general, it is recommended that the depth of the hole saw drill bit be less than 10mm when drilling metal holes.
3. The selection of tooth number and pitch has different cutting properties. We determine the suitable tooth number and pitch based on the hardness and thickness of the cutting material, as well as the structural characteristics of the material.
