It’s crucial that technicians take classes in e-file pedicure techniques before attempting to use an e-file on the foot itself. Any time you use an e-file directly on the skin (as with a hand file), you risk harming the client if you are not trained properly in the technique.
For the toe portion of the pedicure, the best and safest technique is to use a tapered manicure bit. It’s 1,000-grit and has abrasive on the top of the bit to help with gently exfoliating only dead skin (cuticle) from the nail. This also eliminates the need for nipping. For tougher cuticles, the same bit does come in 250-grit and can be used with the same technique.
For very calloused tissue, start with a carbide cut bit such as Kupa’s Medium Typhoon bit. Only use this on the toughest calloused skin. The direction, angle, and speed are all factors in doing this safely and properly. There is no need for using products with acid to soften the callus. In fact, it is better to be completely dry. The second bit is a diamond pedicure bit. This is used in a circular motion and files off more of the dead skin. The last bit is the Easy-Off Mandrel with a smooth sanding band. The technique requires a mist of water as you exfoliate the entire foot using a circular motion.
By working in this order on the skin, you’re basically smoothing it. If you use a rough foot file only, it leaves the skin quite rough. Our technique is similar to what a tech would do to high-shine an artificial nail: Use smoother grit files until the skin is polished.
