• Nail Drill Bit, 6 functions in 1, works with Electric Manicure Machine. Professional e file for nail techs. Multi-function Nail Bit. Mixed 3 sizes, rounded end, 2 way rotate to file. Diamond Coating.
• 3 Sizes Mixed in 1. Special design for the nail bit’s file-teeth. The teeth size is changed from top to end, bigger and bigger. For example, size XXF 6 in 1 nail drill. From top to end of the drill head, the size changes from 4XF at top part, to 3XF at middle part, and XXF at the rest of nail drill head.
• Rounded End. Another special design. It could avoid the collisions when nail techs do nail art works, especially file for long nails.
• 2 Way Function. The file-teeth are cross cut design. The drill could file at FWD or REV rotate directions. Both for right hand and left hand nail techs to use.
• Diamond Coating Process. Diamond coating supply the nail drill with ultra-high hardness, and good wear resistance. It could extend working life 10 to 20 times. Ultra low friction coefficient, and ultra-high thermal conductivity. Reduce frictional heat during polishing, and dissipate heat quickly, let the nail surface less prone to overheating. High density, the polished nail surface is smoother and more delicate. High temperature resistance, and strong corrosion resistance.
• CNC Overall Cutting Process. The e-file was overall cut by CNC machine from 1 tungsten steel. The drill could rotate to file or polish with good balance, and give you an extremely smooth polishing.
