How to recognize high-quality router bits – A guide for professionals

Whether you work in a professional nail salon or maintain your nails at home with an electric nail file – choosing the right drill bit makes a huge difference! But how do you identify high-quality bits, and what are the differences?

How do you identify high-quality drill bits?

There are countless drill bits on the market, but not all are created equal. Pay attention to the following points:

✔ Material quality – high-quality drill bits are made from robust materials like carbide or diamond coating.
✔ Precise craftsmanship – a good bit should be cleanly finished, without rough edges.
✔ Perfect fit – the bit should fit perfectly into the drill and not loosen.
✔ Heat resistance – high-quality bits generate less heat.
✔ Durability – cheap bits wear out quickly and lose their sharpness.

Anela's Pro Tip

"As a juror, I immediately see whether high-quality or cheap bits were used – worn bits leave uneven, imprecise edges. My advice: it's better to invest in a few really good bits than a large assortment of cheap goods. And: drill bits are basic equipment that must be disinfected after each client, not just occasionally wiped." – Anela Mucic, World Champion Nail Design 2023 & INJA Juror

Frequently Asked Questions

How often should I clean and disinfect drill bits?
After every single client, regardless of the bit type. An autoclave or hot-air sterilizer is best for complete sterilization.

What is the difference between diamond and carbide bits?
Diamond bits are particularly suitable for cuticle care and natural nail preparation. Carbide bits are designed for removing gel and acrylic and are usually more durable when working with hard materials.

Can I use the same bit for multiple materials?
Basically yes, but for best results and longer durability, a clear assignment is recommended – for example, one bit exclusively for natural nail care, another only for acrylic removal.
