These high-powered 20mm x 10mm x 4mm x (4mm hole) Neodymium magnets have a countersunk hole that allows them to be drilled or fit into place. They are incredibly strong and commonly used in DIY, crafts, furniture design, fixings, kitchen design, lock mechanisms and science experiments. The Neodymium magnets are coated in Nickel, Copper and Boron to enhance longevity and prevent signs of corrosion. These magnets are designed with one hole that allows them to be easily fixed and drilled into surfaces that aren’t magnetic.
These Neodymium magnets are protected with the world's most advanced coating methods that maximise the longevity and our advanced coating provides a smooth, clean finish that looks aesthetically pleasing. These magnets are produced with one countersunk hole, allowing them to be easily drilled or fixed to surfaces that aren’t magnetic. These high powered magnets have been engineered to the highest ISO standards and they are built to last, however, Neodymium is naturally a fragile material and clashing two magnets together risks magnets from cracking.
Please remember, these countersunk magnets have the same magnetic pole and they will repel each other if two countersunk facing magnets are brought together. If you are magnetising towards a metal plate or other ferrous material, the magnet will magnetise towards it on both polarities.
