Automatic Center Punch Spring Loaded Marking Holes For Start Drilling Metal Wood Plastic Glass

Working principle: Automatic center punch used to produce dents in the workpiece. Its function is the same as a normal center punch, but it does not require a hammer. When pressed on the workpiece, it will store energy in the spring, which will eventually be released as an impulse to drive the punch, thereby producing dents. The pulse provided to the punch is very repeatable, which can produce a uniform impression.
