This product is a ferrite magnet with a counterbore. The difference from ferrite ring magnets is the hole in the middle. The counterbore is mainly used with screws. Due to magnetism and processing problems, most of them choose neodymium iron. Boron counterbore instead, if you need to buy this counterbore ceramic magnet, welcome to communicate with us.
Nowadays, many customers like to use this kind of counterbore ferrite magnet with iron( Pot Magnets ) case to enhance the magnetism.

The magnets with countersunk holes are generally mainly neodymium magnets, mainly because the neodymium material is easy to process and the magnetic force is satisfied. Such ferrite rectangular magnets with (punched) countersunk holes are rare, mainly requiring molds. , If you are interested in this product, you can contact the website customer service or leave a message online....
Ferrite magnets, sometimes referred to as ceramic because of their production process, are the least expensive class of permanent magnet materials. Ferrite magnets became commercially available in the mid 1950’s and has since found its way into countless applications including arc shaped magnets for motors, magnetic chucks and magnetic tools....
