There are two ways to punch holes on the magnet block, one is the straight hole, the other is the sink hole.A straight hole is a common hole, so what exactly is a countersunk hole?A lot of them are designed to make it easy to fit screws, so they need to make holes. So, a hole with 2 heads is actually a hole, and then the screw is put down from the side of the big hole, until the plane of the screw is equal to the plane of the magnet.

The thickness and wall thickness of drilled ndfeb should not be too thin. If the wall thickness is less than 2mm, the product will be 

easily broken and scrapped, which will cause unnecessary consumption.Therefore, drilling ndfeb magnet had better do more than

2.5mm.

With the diversity of market demand, we have contacted ndfeb in more shapes and specifications, but no matter what shape the

magnet is, the size and plating requirements after drilling will be more strict than the general magnet requirements.

The quality of ndfeb on the market is uneven. What exactly affects the quality? The raw material of magnet needs national 

standard, precision of production process and quality control.
