You will be astounded by the power of these magnets! - Neodymium magnets are supplied in power bands or grades. Our normal magnets are already a high N42 grade of neodymium with many suppliers selling lower grades such as N35 or N38. These Magnets are N52, which is the highest grade currently produced by any manufacturer. This is the strongest magnet in the world available in this size.
A pack of 1 - 25mm dia x 20mm thick with 6mm counterbored hole N52 Neodymium Magnet. The SOUTH pole is on the counter bored face and the NORTH pole is on the opposite face. These Magnets are plated with 3 layers of protective coatings - Nickel + Copper + Nickel (Ni-Cu-Ni).
