E-file drill bit (super gold)
Silver color bit, perfect for acrylic removal.
Swiss tungsten carbide for the longest life (3-4 times longer than anything else). The consummate all-rounder. The unique flame cone shape offers, risk free removal of all gel and acrylic. The entire bit, shaft and head, is forged from a single piece of tungsten carbide, not 2! This allows absolute precise build quality and is therefore going to provide vibration free operating. The added bonus is the low heat generated. Good for removing product without fear of cutting your clients.
Carbide bits coatings:
These days Carbide bits are available with different coatings.
Carbide bits are easily cleaned and sterilized. However most coatings may well be removed when ultra-sonic sterilization is utilised.
Uses of Carbide Burrs
Carbide bits are ideal for removing acrylics and other enhancements. However they are not recommended for use directly on natural nail.
An extra coarse grit is best used for removing acrylic and gel overlays and can also shorten and thin down enhancement materials such as hard gels.
A coarse grit is suggested to use on sidewall and also shaping both the fingernails and the toenails. Coarse metal drill bits are used to remove gel topcoat, thin down hard gels or acrylics to speed up the removal process.
The edge at the top of coarse carbide drill bits is sharp thus it is often used to fix acrylic nail cracks.
A medium grit is a great all-purpose bit and is used to shorten acrylic nails, cut in new smile lines, and can reshape the entire surface. Medium metal drill bits are also used to smooth out lumpy spots accidentally formed by acrylics, dipping powder or gel.
Fine grits are generally used to refine the entire surface. Great for shaping of acrylic or gel artificial nail. Should there be some unwanted leftover excess acrylic, a fine burr will help remove it. They are used to clean or smooth out powder along cuticle curves.
A fine grit is also useful in “cutting in” the smile line of shorter acrylic or gel nails.
Most carbide bits are square at the tip. The purpose of this is to refine the surface of the nail. A tapered version will help you get deeper into the corners and around the sides. The typical size of these bits come in 3/32.
Nail techs can choose either single cut or double cut carbide bits for polish removal. Single cut has a cut running semi-vertical down the head that allows polish removal best in one direction. The double cut carbide has cuts in both directions allowing smooth removal of polish in both directions.
Color lines indicate the coarseness of your burr. Simply put the grit is how “rough” your burr is. You can easily tell the difference using the colours.
Yellow is X fine, Red is fine, blue is medium, green is coarse, black is extra coarse, yellow/orange xx coarse and killer 3X coarse is pink.
These colours are by international convention and will always be as per the above.
This is so important to be aware of in understanding Efile bits and their uses.
When to Replace Efile Bits
Your bits and burrs unfortunately also get old and tired. As Albert Einstein used to say, “replacing old and sub standard tools is what separates the good from the great” Well actually he never said that but you can be sure he would have if he had been asked.
An overly vibrating handpiece is very often caused by a drill bit that is no longer balanced.
To check when your bit is damaged or overly worn, check that the shank and its head are in alignment. Best tool for this are your eyes. Do an eyeball check on your bits while they’re spinning to see if they are truly spinning straight or if they are whipping around like a lasso. If you see a sort of blurry ring around a bent bit while it’s spinning fast then you will know the terrible truth. Some will say It’s ok to use them a while longer. However if I agreed with them, we’d both be wrong.
Another way to check for a bent or warped burr is to roll it on a flat surface. Place it in a piece of glass, a tile or even a kitchen counter. Gently roll it with your hand. If the burr is bent you will easily be able to tell.
