Suitable Material:

  • Workpieces with general hardness; such as wood; plastic; PVC plate; iron plate; plate thickness within 3MM.

  • Please note that stainless steel and spring steel are not applicable. Not for quenching. (Water injection cooling while working; it can effectively extend the service life of the drill bit; especially in the case of continuous drilling)

Attention:

  • Because of the outer diameter of each step of the step drill is gradually expanded; then the corresponding cutting resistance and linear velocity will also be gradually increased.

  • Owing to the step drill is completely dependent on the inclined edge that is only with 1mm length; If the feed speed is too fast when drilling; it will be easily to be annealing caused by abrasion of the oblique edge.

  • Please give a downward force when drilling; do not press down too hard to avoid the edge wearing.
