Diamond Drill Bit Rounded Flame-Tipped D-124/3, size 2.0x8 mm

The Diamond Nail Drill Bit with Rounded Flame Tip is a precision-engineered professional e-file bit designed for safe cuticle work, nail wall cleaning, and detailed manicure procedures. Its rounded flame shape provides excellent control and smooth contact with the skin, reducing the risk of injury while delivering consistent results.

Originating from South Korea, these bits feature a distinctive advantage: a slightly softened diamond at the same grit level, which sets them apart from their European counterparts.

Compatible with all standard nail drill machines, the bit features a universal 3/32″ shank and is suitable for daily professional use.
