Frequently Asked Questions

What are diamond drill bits used for?

Diamond drill bits are used in nail care to clean and lift the cuticle, refine sidewalls, smooth the nail surface, and finish detailed manicure and pedicure work. The diamond grit removes material gently and precisely, making them a go-to choice for cuticle prep.

Are KVADRO diamond bits safe for cuticle work?

Yes. The coating is applied only on the working surface, and the even grit distribution gives smooth, controlled contact — helping you work close to the skin with reduced risk of unnecessary contact.

Can diamond nail bits be sterilized?

Yes. KVADRO bits use corrosion-resistant stainless steel and are designed to withstand standard disinfection and autoclave sterilization repeatedly without degrading.

How do I choose the right grit?

Coarser grits remove more material faster and suit prep work; finer grits are better for delicate cuticle work and finishing. Many techs keep a range on hand and match the grit to each step of the service.

Which shapes should I start with?

Flame and Safety Flame bits are popular all-rounders for cuticle work, while Bud, Ball, and Rounded Cylinder shapes cover detailing, undersurface cleaning, and pedicure tasks.
