How to Cut a Neodymium Magnet: Techniques and Safety Tips

Neodymium magnets are among the strongest permanent magnets available today, making them indispensable in industries ranging from industrial manufacturing to consumer electronics. But what if you need a custom size or shape? Can you cut a neodymium magnet safely? Let's explore the best techniques.

Can You Cut a Neodymium Magnet?

Yes, but cutting a neodymium magnet is challenging due to its brittleness and coating. Neodymium magnets are made of sintered material, meaning they can easily crack or shatter if cut incorrectly. Additionally, they are often coated with nickel, which can produce hazardous dust when cut.

Best Methods to Cut a Neodymium Magnet

1. Using a Diamond Blade Saw

A diamond blade saw is the most effective tool for cutting neodymium magnets. This method ensures precision while reducing the risk of cracking.

• Secure the magnet in a vice.
• Use a diamond cutting wheel on a rotary tool or tile saw.
• Apply slow, steady pressure to avoid overheating.

2. Wire Electrical Discharge Machining (EDM)

For industrial applications, Wire EDM is the best solution. This technique allows for precision cutting without physical contact, minimizing damage to the magnet.

3. Waterjet Cutting

Waterjet cutting uses high-pressure water mixed with abrasive particles to slice through magnets without heat damage. This technique is ideal for custom shapes and larger-scale projects.

Safety Precautions When Cutting Magnets

• Wear a protective mask and safety goggles to prevent inhalation of neodymium dust.
• Use proper ventilation, as cutting can produce hazardous dust.
• Handle small pieces carefully, as they can be sharp.
