Rotation Speed:
4-12 Speed: 260-400
4-20 Speed: 180-240
4-32 Speed: 90-160
Note: The outer diameter of each step of the step drill is gradually enlarged, so the corresponding cutting resistance and line speed will be increased.
Because of the step drill, it is fully dependent on the inclined end of only 1mm long, so if the feed speed is too fast during drilling, it is easy to annealed caused by wear on the beveled edges.
Apply downward force when drilling Do not overly hard, avoid wearing the edges.
Suitable Material: Wood, plastic, PVC plate, iron plate, board thickness within 0.1 inch (3 mm) Stainless steel and spring steel cannot be applied. Not intended for sudden cooling.
