FAQ - Frequently Asked Questions

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

Neodymium magnets

Drilling (or sawing) of neodymium magnets is absolutely not recommended. First of all, the material is brittle and fragile. Secondly, drilling causes combustible dust and, thirdly, the heat caused by the drill can possibly demagnetise the material.
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. You should also note that magnets which have lost part of their coating due to drilling will no longer be corrosion-resistant.

Ferrite magnets

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 scarify and break ferrite magnets, but don't expect a clean break.
