Ndfeb Pot neodymium magnet with countersunk hole Pot magnets (Cup Magnets,Mounting Magnets,Holding Magnets) are made up of magnets (NdFeB, SmCo, AlNiCo or Hard Ferrite) and other spare parts, such as metal, plastic, rubber and other components. Sometimes Pot magnets can meet some special requirements while a single magnet can not do. In the meantime, using pot magnets can save more cost than just using magnets and gain the same purpose. Pot Magnets (Cup Magnets,Mounting Magnets,Holding Magnets) are often used as tools for various activities in workshops and in industry. They can be used for holding workpieces whilst welding, cutting, milling or drilling etc. Because of the lack of moving parts and the robust construction of pot magnets, the life is unlimited and no maintenance is required. Just keeping the pole surface clean guarantee reliable operation and a long life. More Pot Neodymium Magnet Details:
