The step hole on the customer's workpiece is still chamfered. If it is done with several drill bits and chamfered knives, it will require frequent tool change and waste processing time! The processing efficiency is low, if the forming knife is processed once, the efficiency is high, and the positioning is not repeated, and the processing accuracy is high
