Can I drill a hole in a magnets or saw them?

Neodymium magnets

Drilling (or sawing) of neodymium magnets is not recommended for the following reasons:
  • The material is brittle and fragile.
  • Drilling causes combustible dust.
  • The heat caused by the drill can possibly demagnetise the material.
  • Due to the missing coating at the borehole, magnets are no longer protected from corrosion.
Specialists can work with the magnets with specialised diamond-tipped tools and constant water cooling. However, this normally occurs prior to magnetisation of the material.

Alternative: Magnets with hole

Luckily you can buy neodymium magnets with borehole directly at our web shop.

Ferrite magnets

Breaking edge of a scratched ferrite magnet
Drilling (or sawing) of ferrite magnets is not recommended. The material is brittle and fragile. Specialists can work with the magnets with specialised diamond-tipped tools, constant water cooling and a high rotation speed. However, this normally occurs prior to magnetisation of the material.
You can try to slightly slit and break ferrite magnets, but don't expect a clean break.
You don't need to drill yourself; we also carry screw-on ferrite pot magnets in our web shop:
