MODULE 25
PILIREA CU FREZA ȘI DEMONTAREA MATERIALULUI
Surface control, material removal, and protecting the natural nail
The e-file should shorten your working time, not cause you fear.
In this course, I will show you how to choose the right bits, how to control the direction, speed, pressure, and position of the e-file, and how to remove material without touching or thinning the nail plate.
You will learn surface filing, removal during refills, cleaning under the nail, and how to control every movement. The goal is to work faster, safer, and without causing the client heat, pain, or sensitivity.

The logic of a milling cutter end
We don’t choose a bit just because it’s expensive or because we saw it in a tutorial.
You will learn to analyze:
- The material it is made of.
- The shape.
- The diameter.
- The length of the active area.
- The grit.
- The cutting direction.
- The balance of the bit.
- The vibrations.
- The purpose for which it was created.
- The condition and degree of wear.
A professional bit can help you work with more control, but price alone does not guarantee results. What matters is the quality, the balance, the durability, and using it at the right stage.
Choosing the grit size
You will understand:
- When to use a fine grit.
- When to choose a medium grit.
- When a coarser grit is necessary.
- Why you don't use the same bit for every product.
- How material hardness influences the choice of bit.
- Why a bit that is too fine can heat up the material.
- Why a bit that is too coarse can become dangerous without control.
- How to recognize a worn-out bit.
Sense of purpose
You will learn:
- The difference between forward and reverse.
- How to choose the direction based on your dominant hand.
- How to work on the right side and the left side.
- How to prevent the drill bit from slipping.
- How to position the client's finger.
- How to keep the bit stable on the surface.
- Why the direction of movement must follow the way the bit cuts.
Position, pressure and speed
Control does not come from pressure.
You will learn:
- How to support your hand.
- How to stabilize your finger.
- How to use the active area of the bit.
- How to avoid working with the tip.
- How to keep the bit in motion.
- How to choose the speed based on the bit and material.
- How to reduce the sensation of heat.
- Why a bit that stays in one spot too long heats up.
- How to adapt pressure to the thickness of the material.
Surface filing
I will show you how to control:
- Removing the top coat.
- Removing the color.
- Reducing the thickness.
- Correcting unevenness.
- Cleaning the cuticle area.
- Preparing the material for maintenance.
- Preserving the stable layer.
- Checking the thickness from a profile and frontal view.
We do not remove all the material at every maintenance session if the remaining base is stable and secure. We remove what is necessary and keep what can support the new structure.
Lifting removal
You will learn:
- How to identify the limit of the lifting.
- How to work from the stable material towards the lifted area.
- Why you should not aggressively go under the lifting.
- How to avoid touching the natural nail plate.
- How to check if any unstable material remains.
- When you can continue with the maintenance.
- When it is necessary to remove a larger area.
Lifting must not be covered or kept under the new material.
Subungual filing
Subungual filing helps you clean, thin out, and correctly define the structure, but it must be performed in a controlled manner.
You will learn:
- When it is necessary.
- When it should not be performed.
- How to check the position of the hyponychium.
- How to protect the skin.
- Which bit to choose.
- In which direction to work.
- How to clean excess product.
- How to thin the edge without weakening it.
- How to correct the lower sidewalls.
- How to achieve a cleaner and sleeker structure.
- How to avoid contact with the natural nail.
Do not insert the drill bit under the nail without visibility and do not force the area when the hyponychium is close.
Complete disassembly
You will learn:
- In what situations it is necessary.
- How to reduce the material in stages.
- How to change the bit as you get closer to the natural nail plate.
- How to recognize the base layer.
- Why you should not clean aggressively down to the natural nail.
- How to maintain a protective layer when the situation allows it.
- How to check the final surface.
- How to avoid sensitivity after removal.
Filing with an e-file during maintenance
I will show you a logical process:
- Analyze the work.
- Check for lifting and cracks.
- Shorten if necessary.
- Remove the top coat and color.
- Reduce the thickness.
- Completely clean off the lifting.
- Keep the base stable.
- Correct the material under the nail.
- Prepare the surface for the new architecture.
This way, you no longer make unorganized movements and stop wasting time going back to the same areas.
Mistakes that cause pain and sensitivity
You will learn how to avoid:
- Excessive pressure.
- Incorrect speed.
- Working in a single spot.
- Worn-out bit.
- Wrong angle.
- Using the tip of the bit.
- Touching the nail plate with an aggressive bit.
- Excessive removal.
- Filing without support and visibility.
- Forced cleaning of the subungual area.
More control. Less fear. Less working time.
After completing the course, you will have clear guidelines for:
- Choosing the right bit.
- Controlling the direction and speed.
- Quickly removing color and bulk.
- Keeping the material stable.
- Eliminating lifting.
- Performing under-nail filing.
- Performing a safe removal.
- Protecting the natural nail plate.
- Avoiding heat and sensitivity.
- Shortening working time without sacrificing safety.

Education born from experience
I am Ioana Diana, nail trainer and founder of ONE Nail Academy and the ONE brand.
I created this module so that the e-file becomes a controlled tool, not a source of fear.
I don't want you to just memorize my hand movements. I want you to understand what you are doing, why you are doing it, and what to check when the result is not what you expected.
