Professional Tips
The blue marking indicates medium abrasiveness, providing more active processing than fine red variants.
The 2.1 mm working diameter offers a practical balance between accuracy and treatment efficiency.
Use light, controlled pressure, especially near the natural nail plate and delicate skin.
Allow the diamond coating to perform the abrasive action instead of pressing heavily.
Keep the rotating bit moving continuously rather than concentrating on one point.
Choose a finer abrasive when more delicate finishing is required.
Thoroughly clean debris from the diamond surface after each procedure.
Replace the drill bit when its abrasive efficiency noticeably decreases.
