Magnets should not be drilled as they are brittle and are likely to break during the drilling process. There are several other complications that can occur when drilling a magnet. If you feel the need to drill a magnet, then take a look at our recommended suitable alternative magnets below and avoid all possible complications.
Drilling or sawing both neodymium and ferrite magnets is not recommended.
However, certain specialists use diamond-tipped tools and constant water cooling can work on magnets, however, this is usually prior to the magnetisation of the material.
Why you shouldn’t drill Neodymium or Ferrite magnets
You can try to drill, saw or score and break neodymium and ferrite magnets but we strongly encourage you to avoid this whenever possible, this is because:
- The materials are fragile.
- The materials are brittle.
- The drilled hole would be missing all coating, making the magnet not protected from corrosion.
- The heat caused by a drill can potentially demagnetise the material.
Luckily here at FIRST4MAGNETS if you’re looking for a magnet with a hole already drilled then be sure to browse our vast range of Pot magnets. Available in both Neodymium and Ferrite material.
Or check out our range of Neodymium Countersunk Magnets. Countersunk magnets have a central hole which allows them to be fixed to non-magnetic surfaces with a screw.
