C & I Nail Drill Bit 6-in-1 E-file | Diamond-Coated CNC Tool for Nail Techs

Meet the C & I Nail Drill Bit 6-in-1

Designed for professional use with electric manicure machines, this compact bit packs six filing options into a single head. The rounded end helps maintain control during long-nail art and reduces the risk of accidental grazing, while the teeth are engineered to transition in size from top to end for varied shaping tasks. A diamond coating delivers ultra-hard wear resistance, helping the bit stay sharp through busy studio days and frequent polishing sessions. The result is a tool you can rely on for smooth finishes without compromising precision.

Built for consistency, this e-file bit leverages a CNC overall cutting process to balance rotation and provide a refined, even surface. The design also incorporates a cross-cut tooth pattern that works with forward or reverse rotation, making it suitable for both left- and right-handed technicians. With a total length close to traditional nail bits and a shank that fits standard machines, it slots seamlessly into existing workflows.
