Professional Tips
Red indicates fine abrasiveness, making the bit suitable for delicate processing and finishing.
The 2.5 mm diameter provides greater coverage than narrower P862 variants while retaining good maneuverability.
Apply light pressure, particularly when working near the natural nail plate or delicate skin.
Keep the drill bit moving continuously rather than holding it against one point.
Use a narrower P862 size when maximum precision in very small areas is required.
Select a medium-abrasive variant when stronger processing is necessary.
Clean debris thoroughly from the diamond-coated surface after each procedure.
Replace the drill bit when its abrasive efficiency noticeably decreases.
