Brushed vs. Brushless: The Secret Behind Quiet Nail Drills

When choosing a nail drill, professionals often first consider the device's power and durability—and rightly so! A powerful, long-lasting motor is essential in any nail salon. But there's another factor that's becoming increasingly important: the nail drill's noise level .

For many clients, a nail treatment is a moment of rest, relaxation, and self-care—true me-time . And you, as a nail technician, also find it more comfortable to work in a quiet environment without distracting background noise. A silent nail drill therefore contributes to greater comfort, a professional atmosphere, and less fatigue at the end of the day.

But why are some milling cutters so much louder than others? It all has to do with the type of motor : brushed or brushless . In this blog post, we'll explain the difference and show you which of our Seayang machines use which type of motor.

What is a brushed motor?

A brushed motor is a classic motor that uses carbon brushes that make contact with the rotating rotor. This system is effective, but due to the frictional contact:

• makes the engine noisier ,
• he vibrates more,
• the brushes wear out over time,
• and therefore more maintenance is required.

Examples of brushed milling at Seayang:

Seayang Champion 3

Seayang K35

Seayang Mighty

These devices are all very robust and powerful , and their performance is certainly on par with models with a brushless motor. They are built to last and deliver excellent results.

The only difference? They're a bit louder in use – a typical characteristic of router bits with a traditional carbon brush motor.

Still, they're perfectly suited for those looking for a reliable and powerful entry-level model with excellent value . In short: a smart choice for those who want quality without immediately upgrading to a more expensive brushless model.

What is a brushless motor?

A brushless motor works without carbon brushes. Instead, electrical signals are used to turn the rotor. This offers several advantages:

• Much quieter in use
• Less vibrations
• Longer life (less wear)
• Higher efficiency and less heat generation
• Maintenance-free

Examples of brushless milling at Seayang:

Seayang K38

Seayang Cyclone Vac (with integrated extraction system)

These machines are extremely quiet and comfortable to use , making them perfect for professional use or salons where you mill all day long .

Thanks to the brushless motor, they not only offer less noise but also greater durability and reduced wear . This means less maintenance and a longer lifespan.

A silent nail drill creates a calm atmosphere in your salon , which is not only pleasant for you as a nail technician but also extra relaxing for your clients. Ideal for those who value quality, comfort, and a professional appearance.

Which one should you choose?

• Do you work occasionally or have you just started? Then the Champion 3 , Mighty , or K35 are excellent choices.
• Want maximum silence, comfort, and durability? Then choose a K38 or the powerful Cyclone Vac .

Whether you choose a brushed or brushless motor, proper maintenance and use are always important. So be sure to check out our other blog post about the do's and don'ts of nail drills.
