Why You Shouldn’t Always Use a Medium Grit E-File Bit for Product Removal
Be honest. When you pick up your e-file to remove product, do you automatically reach for your medium grit carbide bit?
You probably do.
And you’re definitely not the only one!
Medium grit has become the comfort blanket of the nail industry.
It’s the one many technicians learn with, the one they feel confident using and the one they automatically reach for when it’s time to remove or reduce product.
But here’s something I want more nail technicians to understand.
Just because medium grit CAN remove the product doesn’t mean it’s the BEST grit for the job.
In fact, using medium for absolutely everything could be making your appointments longer and creating more work for yourself.
Let’s talk about why.
1. Medium Grit Isn’t a One Size Fits All Bit
There’s a reason carbide e-file bits come in different grits.
They have different jobs.
Think about your manual nail files.
Would you choose a 240 grit file to remove a thick acrylic enhancement?
Probably not.
Could you eventually reduce the product with it? Yes.
Would it be the most efficient choice? Absolutely not.
So why do so many nail technicians do the equivalent with their e-file?
They reach for medium grit regardless of whether they’re removing a thin layer of builder gel or debulking a thick acrylic enhancement.
Different amounts of product require different levels of cutting action.
As a general guide:
- Extra Fine: Polishing and delicate enhancement refinement. Comparable in intended use to a 220/280 grit buffer.
- Fine: Refining thinner product areas, such as enhancement material near the cuticle. Comparable to a 240 grit file.
- Medium: Standard debulking and infills. Comparable to a 180 grit file.
- Coarse: Heavier removal and debulking of products such as acrylic and hard gel. Comparable to a 150 grit file.
- Extra Coarse: Removing the thickest product bulk with the most aggressive cutting action. Comparable to a 120/100 grit file.
These are approximate comparisons to help you understand their intended uses, not exact grit equivalences. Carbide bits use cutting teeth rather than abrasive particles, and the actual cutting action varies between bit designs and manufacturers.
The question shouldn’t be, “Which bit do I always use?”
It should be, “Which bit is most suitable for what I’m trying to remove?”
2. Your Medium Bit Could Be Costing You Valuable Time
Imagine you’re completing an infill on a client with thick acrylic enhancements.
There’s a substantial amount of product to reduce before you can begin rebuilding the structure.
You pick up your trusty medium bit.
You make a pass.
Then another.
And another.
You’re working your way across the enhancement, repeatedly reducing small amounts of material.
Eventually, you get there.
But what if you’d selected an appropriate coarse bit for the initial bulk reduction?
You may have been able to complete that stage much more efficiently.
You’re not necessarily a slow nail technician. You might simply be using a bit that’s too fine for the job.
And if you’re doing 5-6 clients a day, those unnecessary minutes can quickly add up.
Saving time isn’t about increasing pressure, using unsafe speeds or rushing.
It’s about selecting the right tool for the amount and type of product you need to remove.
3. Using a Finer Bit Doesn’t Automatically Mean You’re Being Safer
This is one of the biggest misconceptions surrounding carbide e-file bits.
Many nail technicians instinctively associate finer grits with safety.
They think:
“Medium is safer than coarse.”
“I don’t want to use anything too aggressive.”
“I’d rather stick with medium because that’s what I’m comfortable with.”
And while a coarser bit generally removes more material with each pass, grit alone doesn’t determine whether a technique is safe.
Safety depends on several factors, including:
- Your training, control and experience
- The thickness and type of enhancement product
- The design and condition of the bit
- Your e-file speed and direction
- The pressure you apply
- Your working angle and contact time
A medium bit used incorrectly can still cause damage.
And a coarse bit used correctly for suitable bulk enhancement removal can be an appropriate, efficient choice.
That’s not to say everyone should immediately switch to coarse or extra coarse.
More aggressive cutting bits require appropriate training, control and sufficient enhancement thickness.
The safest bit is the one that’s appropriate for the task and used correctly, not automatically the one labelled medium.
4. Repeated Passes Aren’t Always Better
Something I regularly want technicians to think about is how much unnecessary work they’re creating.
When a bit is too fine for heavy product removal, you may find yourself repeatedly going over the same area.
- More passes
- More time
- More opportunity for friction and heat
It’s important to understand that heat isn’t simply determined by how coarse your bit is.
Pressure, contact time, speed, the condition of the bit and your technique all play a role.
Using a finer bit with excessive pressure or repeatedly dwelling on the same area isn’t automatically safer than using a more appropriate cutting grade.
Of course, a coarse bit can also cause heat, discomfort or damage when used incorrectly.
The goal is always controlled, appropriate product reduction.
Don’t confuse taking longer with working more safely.
If you’re repeatedly filing the same thick area without making efficient progress, assess whether your bit selection is suitable.
5. Coarse Doesn’t Mean You Have to Be Aggressive
Let’s get one thing straight.
Coarse describes the cutting action of the bit. It doesn’t mean your technique is therefore aggressive.
You should never need to force an e-file bit through enhancement product.
If you find yourself pressing harder to make a medium bit remove thick material, that could be a sign that you need to reassess your equipment or technique.
A correctly selected bit should perform its intended job with controlled movements and appropriate pressure.
For thick acrylic and hard gel, a coarse carbide bit may be more suitable for the initial reduction stage.
For particularly heavy product bulk, extra coarse may be appropriate in trained hands.
But as you approach thinner enhancement layers, it’s important to change to a less aggressive cutting action when required.
Think about it in stages.
Heavy bulk? Choose a suitable coarse bit.
Standard debulking? Medium may be ideal.
Thin enhancement areas? Consider fine.
There’s no prize for completing the entire service with the same bit.
6. You Don’t Have to Use One Grit for the Entire Appointment
This is where understanding your carbide bits can make such a difference.
Let’s say you’re completing a maintenance appointment on a client with thick hard gel enhancements.
Rather than using medium grit from start to finish, your approach might look something like this:
Stage 1: Coarse for initial bulk reduction
Remove appropriate excess enhancement material where sufficient product thickness is present.
Stage 2: Medium for standard debulking
Once the thicker bulk has been reduced, switch to medium where more controlled removal is required.
Stage 3: Fine for precise enhancement refinement
Use a finer cutting action to refine suitable thin product areas, staying clear of the natural nail and living skin.
You’re matching the cutting action to the stage of the service.
That’s a much more considered approach than automatically reaching for the same medium bit every time.
And remember, not every appointment requires 3 different bits.
The point isn’t to use more tools unnecessarily.
It’s to use the right tool at the right time.
7. Your Bit Choice Should Depend on the Product You’re Removing
Not all enhancement products behave the same way.
A thin layer of builder gel doesn’t necessarily require the same approach as thick acrylic.
Likewise, a dense hard gel enhancement may require a different cutting action from a small amount of product left during an infill.
Think about what you’re actually removing.
Thin product layers
Fine or medium may be appropriate depending on the product, thickness and location.
Standard infills and rebalances
Medium is often an excellent choice for routine debulking and product reduction.
Thick acrylic or hard gel
Coarse can be more efficient for removing significant bulk.
Very thick enhancement product
Extra coarse may be useful for initial heavy reduction when appropriate and when used by a suitably trained technician.
Soak off products
Remember that not every product needs to be completely filed away. Follow the manufacturer’s removal system, including soaking where required, and avoid cutting into the natural nail.
Choose your grit based on the material in front of you, not the bit you’re most used to holding.
8. The Habit of Always Choosing Medium Could Be Holding You Back
Let’s be honest.
Sometimes we keep doing things a certain way simply because that’s how we’ve always done them.
You were taught with a medium bit.
You bought a medium bit.
It worked.
So you’ve carried on using medium for everything.
And there’s nothing wrong with feeling comfortable with your tools.
But as professionals, we should be constantly developing our understanding of WHY we’re using them.
Not just repeating the same routine because it’s familiar.
Ask yourself:
Am I choosing medium because it’s genuinely the best bit for this job, or because it’s the one I’m comfortable with?
That’s an important distinction.
Confidence should come from understanding your equipment, not from limiting yourself to one option.
And if you’re unsure about different grits, get appropriate training and practise under professional guidance before introducing more aggressive bits into client services.
9. Faster Removal Doesn’t Mean Lower Quality
I talk a lot about saving time as a nail technician.
But I always come back to the same point.
Working more efficiently should NEVER mean cutting corners.
There is a difference between rushing through a treatment and improving your technique.
Removing unnecessary enhancement bulk efficiently doesn’t mean skipping important steps.
Choosing a coarser bit for thick product doesn’t mean sacrificing nail health.
And changing grits when required doesn’t mean you’re doing something more complicated.
It means you’re adapting your technique to suit the service.
If a suitable coarse bit allows you to reduce the initial bulk more efficiently, you may have more time available for the parts of the appointment that require precision.
Like creating the correct structure, refining the enhancement and delivering a beautiful finish.
Efficiency isn’t about doing less. It’s about making better decisions about how you work.
10. When Medium Grit IS the Right Choice
After all that, I want to make something very clear.
Medium grit isn’t a bad choice.
Far from it!
It’s a brilliant, versatile option for many enhancement services.
Medium is particularly useful for standard debulking, routine infills, general product reduction and refining appropriate areas of existing enhancements.
There’s a reason it’s such a popular grit.
The problem isn’t using medium.
The problem is ONLY using medium, regardless of the job.
Sometimes medium is exactly what you need.
Sometimes fine would give you greater precision.
Sometimes coarse would make thick product reduction more efficient.
And sometimes extra coarse is appropriate for very heavy removal.
The skill is knowing the difference.
The Takeaway: Stop Automatically Reaching for Medium!
Next time you pick up your e-file, I want you to think about what you’re trying to achieve BEFORE choosing your bit.
- How thick is the product?
- How much material needs removing?
- What enhancement system are you working with?
- And how much precision does the task require?
Don’t just grab medium because it’s what you’ve always used.
Choose your carbide bit with purpose.
Because being a skilled nail technician isn’t about using the same tools for every client.
It’s about understanding your tools well enough to know when to use something different.
And if choosing the correct grit makes your appointments more efficient without compromising control, safety or quality, why wouldn’t you?
