Ndfeb magnets with holes are generally straight holes (through holes) or countersunk holes. Today, we mainly take you to understand the relevant knowledge such as the size diagram of NdFeb countersunk magnets.
Ndfeb countersunk magnets, also called countersunk holes or screw holes, are commonly found in the two shapes of round and square. The middle countersink hole is mainly used with screws to fix the magnet around. Usually thickness direction magnetization, professional point is axial magnetization.
Countersunk Magnet Dimension Drawing:
The dimensions of countersunk magnets are usually identified by the diameter of the countersunk hole, the diameter of the through hole, the height or the angle (usually 90 degrees).
The drawings below are dimensional drawings of countersunk holes for the more common shapes.

Is the countersunk magnet difficult to process?
The processing process is slightly more than the normal through hole process, because the sintered neodymium magnet material characteristics, brittle and fragile, countersunk holes are mostly processed on the basis of through holes, and now the use of countersunk magnets is high, so the processing is not too difficult.
How to use countersunk magnet?
There is a screw hole in the middle of the countersunk magnet, which is generally used with the screw and fixed on the non-magnetic surface. In many applications, there may be two pieces used together, at this time, the principle of magnets repulsion and opposites attract is needed. Countersunk magnets have many uses, and are useful to many industries such as home and industry.
