A regular cylinder has a flat end with an edge that can leave a groove if you tilt it. A rounded cylinder keeps the straight working surface but softens the end, which makes it more forgiving close to the skin.
About this bit
The Staleks Expert FA30R023/8 is a rounded-cylinder diamond bit with a 2.3 mm head and an 8 mm working length. Its red band means soft abrasiveness, intended for delicate skin and natural nail work.
Where it shines
- Cleaning dry skin along the lateral nail folds in one long, even stroke.
- Working around the proximal fold after the cuticle has been lifted.
- Gentle smoothing near the skin where a pointed bit would dig.
How to hold it
Keep the long side of the bit parallel to the fold and let the rounded tip lead. Use light pressure and steady movement. If you need to reach a deep corner, switch to a flame rather than forcing the cylinder in.
Pairing suggestions
Many techs pair a ball bit for lifting, this rounded cylinder for the folds and a slim flame for corners. With those three shapes most natural-nail cuticle prep is covered.
Clean, disinfect and dry the bit after every service. Product details: Staleks FA30R023/8 rounded cylinder bit
