The difference between milling cutters and drill bits: Milling cutters can mill planes, slots, and holes; drill bits can only drill holes, and they can only drill holes corresponding to their own size! The milling cutter you mentioned can be used with an electric drill, but it can only slowly mill an irregular round hole on soft materials, because there is no positioning point at the front end like a drill bit, and it is easy to suffer excessive force. Broken! The front-end structure of the drill bit ensures that the drill bit has sufficient drilling and cutting force, so the uses are incomparable!
Milling machine and drilling machine: The milling machine can move up and down and horizontally during processing, so it can mill faces and holes or drill holes; the drilling machine can only move up and down during processing, so it can only drill holes!
