Can I drill a hole in magnets or saw them?
Since magnets are brittle and can break during drilling or sawing, we do not recommend such methods. Find out below what other complications can occur when machining magnets and which magnets are a suitable alternative.

Neodymium magnetsDrilling 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 drilled hole, 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.
Ferrite magnetsDrilling (or sawing) of ferrite magnets is not recommended. The material is brittle and fragile. Specialists can work with the magnets using specialised diamond-tipped tools, constant water cooling and a high rotation speed. However, this normally occurs before the magnetisation of the material.
You can try to score and break ferrite magnets, but don't expect a clean break. You don't need to drill yourself; because we also carry screw-on ferrite pot magnets in our online shop.
In our theme categories, you will find a list of all magnets with a hole. This includes ring magnets made of neodymium or ferrite as well as neodymium magnets with a hole or thread.
