Can NdFeB strong magnets be punched?

Usually, Neodymium Magnets are mainly punched with countersunk holes, and there are also straight holes. For example, the processing method of the countersunk hole Ring Magnet is to dig holes or drill holes again after slicing processing, and the processing technology requirements are more particular. If a Strong Magnet already has a magnetic force, it needs to be demagnetized first, then drilled, and then re-magnetized after the appearance of the finished product is completed. Generally, it is mainly made of cylindrical or square cylindrical magnets.
