Product Description

These high-powered 50mm x 12mm x 4mm x (4mm Hole) Neodymium magnets have two countersunk holes that allow 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. These neodymium magnets have an epoxy coating which is one of the most durable forms of coating available. Epoxy magnets do not corrode like traditional Ni-Cu-Ni coated magnets and are perfect for wet humid and salty environments. These magnets are designed with two holes that allow them to be easily fixed and drilled into surfaces that aren’t magnetic. 

Quality Assurance

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 TWO countersunk holes, 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.
