Our 25mm (1") x 20mm (0.8") counter-bored circular magnets are the largest in our counter-bored range and provide an astonishing 22kg (48.51lbs) magnetic pull. These magnets make excellent magnetic stud finders and can even be used to guide wires and cables through cavity walls by connecting a piece of steel to the cable and using the magnet to guide it along a wall or ceiling. Also, counter-bored magnets with opposite poles on the counter-bored face can be used to attract two surfaces or two opposing counter-bored magnets with the same pole on the counter-bored face can be used to create a dampening, shock absorbing or repelling effect. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully. Also available with the north pole on the counter-bored face.
