The Victoria Vynn Nail Drill Bit Ceramic Cone 4mm is a professional ceramic e-file bit with a narrow rounded cone working head. It is intended for refining tips and the underside of the free edge on hybrid, gel and acrylic-gel structures, giving trained nail technicians a clearly specified profile for matching the bit to the service stage.

Head design and application The slim head reaches beneath the free edge for precise correction without a bulky profile. The listed abrasive or cutting grade is medium, and the head size is 4 mm.

Universal salon shank A 2.35 mm shank fits compatible twist-and-lock manicure and podiatry handpieces. The bit is designed to tolerate compatible aqueous disinfection and autoclave sterilisation when the equipment and process are validated for the material.
