Here’s the million-dollar question: What is a drill bit? For a newbie, it can be puzzling since you have to keep up with a lot of nail products and techniques. The beginning can be challenging. It’s a heady mixture of excitement and cluelessness, especially when you’re in the mood to work with a new e-file.

iGel Beauty is here to help you out on your drill-ema! We have already run through the ins and outs of an e-file. Now it’s time for you to understand the essence of a drill bit.

What is a Drill Bit?

drill bit is a rotating nail file that you place on your nail drill to function as an automatic buffing machine. It’s a crucial piece to complete your e-file; it won’t work correctly without the drill bit.

Drill bits are used to shave off or remove nail polish off your nails. It comes in a variety of sizes, shapes, and grits. Although you may be surprised at how a small piece of metal can make such a big difference in your nails, you must understand how it works. 

Drill bits create friction, which helps remove nail polish quickly. Drill bits can remove nail paint 2-4 weeks old, depending on the pace and frequency with which it is used.

The drill bits from iGel Beauty are easy to disinfect because they are acetone-proof. The usual size is 3/32, but you can only use 1/8 for a specialized nail drill. Therefore, the 3/32 drill bit size is the most excellent option since it’s the general size for e-files. Of course, with good care and usage, the drill bit can last a long time.

What is your preference, Coarse or Medium?

The answer is based on what will best fit your needs and where you feel most at ease. Coarse is a superior option for speed for more experienced users. For safety, however, it needs skill and precision. We recommend using a Medium or Fine grit with rounded edges for safety for those just starting as a nail tech or training.

For natural nails, we recommend the Fine bit if it’s your first time. Professionals typically utilize the Medium or Coarse bit for natural nails because altering them can be time-consuming and inconvenient. More traditional methods, which use three to four distinct drill bits, may be used by nail technicians with years of experience.

How do I connect the drill bit to the nail drill?

1. Rotate the dummy drill bit clockwise to remove it. An unlocked icon will appear.

2. Insert your preferred drill bit.

3. Lastly, rotate the silver part of the E-File counter-clockwise to secure your drill bit.
