Our under nail drill bit items will also come in the most popular textures called grits. That will enable the user to meet most of the nail preparation needs. The surfaces may, for example, feature fine, medium, coarse, superfine, super-coarse, etc.

Under the nail drill bit is straight and thin with the same size and design as its shank. Nonetheless, it will feature a safety tip that can also trim the edges of your cuticles without damaging them.

What’s the Function of Under Nail Drill Bit?

Under nail drill bit has an excellent design, suitable for cutting, removing, trimming, cleaning, drilling, grinding, or shaping artificial nails.

Under nail drill bit fits perfectly under the bottom of artificial nails and remove dust or bulks with excellent efficiency. Besides, it removes the materials at a high-speed rate saving your time in half.

Syndent supplies the best drill bit for under nail with extended barrel tips for cutting purposes. Made with a unique style and grade material, the barrel type produces peak and cutting, and resilient durability.

The bit will accurately cut artificial nails, including acrylics, gel, powder nails, etc. Moreover, you’ll use the UNC to polish and smooth the bottom of false nails.

The UNC will flexibly reach the sidewalls of the nails and cuticles. Hence, it will remove materials without harming your skin and false nails.

What’s the Difference Between Under Nail Drill Bit with Flutes and Partials?

Under nail drill bit products will feature unique designs based on the cutting edges. Usually, the type of material used to fabricate the bits will determine the cutting edges.

We have various materials used in fabricating UNC products like steel, ceramics, tungsten carbide, diamond, etc. However, Syndent uses diamond, tungsten carbide, or ceramic materials in most manufacturing processes.

Tungsten carbide remains the most commonly used drill bit in the nail beauty industry.


Because tungsten carbide material has two powerful elements, tungsten, and carbon, the two materials combined produce tools with optimum strength. Moreover, they have quality durability and sharp-cutting properties.

Tungsten carbide is an anti-rust element with high resistance to temperature and other environmental effects. And because of its sharp cutting properties, it will offer quick and efficient results when doing your nail preparation.

Carbide under nail drill bit has flute-like cutting edges which look like sharp blades. The sharp flutes will therefore shave off materials or dirt in bulk in the shortest time possible.

The benefit of working with a fluted UNC bit is that it reduces friction at a more significant margin. However, as a result, it develops some heat during the nail preparation process.

Ceramic under nail drill bit has flutes just like the carbide bits. And like the counterpart, ceramic UNC will remove material through cutting and not grinding.

Therefore, you’ll incur reduced chances of heat generation. Plus, the bit will produce quick and accurate results.

Ceramic bits remain popular because of their high heat dissipation compared to other types of nail drill bits. Moreover, ceramic under nail drill bit has impressive service life and optimum strength. Thus, the tool will prepare and help you make desired shapes on the nails.

Diamond is the precious and most brutal metal available. Therefore, under nail drill bits that bear such components feature excellent strength. Plus, a diamond under nail drill bit will produce tremendous service life.

However, diamond UNC bits appear different from other bits in that the cutting edges occur in the form of partials. Consequently, manufacturers will place partials on the grinding head through natural or artificial means.

Unlike ceramic and tungsten carbide, diamond under nail drill bit items scratches or grinds the nail surface. Therefore, the process can create heat easily due to high friction.

More so, diamond UNC leaves scratches when debulking the artificial nails. Thus, you’ll require a finer bit when you want a smooth finish on the nail surface.

Diamond under nail drill bit will work well on the sidewalls and when trimming cuticles. It can trim cuticle edges and remove dirt around the cuticle area.

Does Under Nail Drill Bit Comprise of Various Textures?


The best drill bit for under nail cleaning can encompass sound textures, called grits. The grits essentially help to achieve the preferred smoothness.

Also, differences in the degree of coarseness provide a certain percentage of cutting sharpness.

Under nail drill bits come in the three most popular textures; coarse, medium, and fine. But, manufacturers provide other surfaces like superfine (extra fine), super coarse (extra coarse), 2 extra-fine, 2 extra-coarse, etc.

For instance, a coarse grit under nail drill bit is a very sharp tool you use to prepare nails. The partials or the flutes appear somehow scattered but every dip. It makes the bit have incredibly sharp cutting properties than the medium or fine-textured bit.

With a coarse UNC bit, you’ll not try using it on the surface of natural nails. It is because the sharp edges work like very sharp blades or knives. And because natural nails are very soft, the bit will cut through them quickly and damage the soft tissue.

Only choose coarse or extra coarse UNC when preparing artificial nails. That implies cutting acrylic nails, gel nails, dip powder, gel polish, hard toenails, etc.

Medium grit under nail drill bit has slightly packed flutes/partials than the coarse grit. Hence, manicurists will have the benefit of using it in various applications.

As a versatile tool, the medium grit UNC can polish, smooth, polish, engrave, design the shape of the nail, etc. It also removes dirt and cuticles underneath and on the sidewalls.

On the contrary, a fine-textured under nail drill bit has very packed partials/flutes. It, therefore, makes the UNC suitable for delicate nail artwork tasks.

The edges of a fine under nail drill bit are also sharp but not like the coarse or medium grit. Thus, you’ll have 100% smoothness in any nail preparation. Moreover, it will provide final polishing after using a diamond type.

Can Under Nail Drill Bit Burn Your Natural Nail?

Because of its distinctive design, under nail drill bit will not burn the nails, especially when done by a tech. Instead, a qualified user will control the bit and determines the amount of pressure ideal for nail preparation.

Observing the heat rule is essential when using under nail drill bit or any other similar tool. The heat rule indicates that for friction to occur, pressure remains eminent. And friction will result in heat.

If you don’t apply pressure while cutting the nail bit, the client will not feel the heat. Moreover, if you have a fresh under nail drill bit, you don’t need any pressure to do nail preparation. However, you’ll only need a constant movement of the bit with light or no pressure to minimize heat.

Sometimes a burn can occur due to a client pressing the finger on the machine because of tension. However, if you explain the heat rule, the client will cooperate and relax the hand. That will eventually avoid chances of discomfort to the hand because of heat.

How Often Should You Replace Under Nail Drill Bit?

The best drill bit for under nail cleaning should serve you for the longest time under good user maintenance. Good maintenance essentially improves the longevity of the bit.

Proper maintenance includes giving the bit a good clean-up. And it involves using a fine brush to clear dirt and debris stuck between cutting edges.

Then use the correct industrial chemical to disinfect the UNC bit. It practically kills germs and makes it cleaner.

Nonetheless, a UNC’s durability may depend on certain factors like usage rate. Consequently, the frequent application indicates that the bit may not serve longer than that used on a few occasions.

The material that the under nail drill bit cuts and how you use it can also determine the longevity. A UNC should practically perform the job designed to do and only process fingernails. Otherwise, processing other materials that seem a bit complex makes the tool wear out faster than expected.

These are essential indicators that show your bit needs a replacement. First, your tool needs relief when it doesn’t cut faster than it used to perform. It implies the edges of the device have lost their cutting abilities due to wear.

Blunt edges usually come from the intensive or wrong use of the bit when preparing nails. Therefore, apply the required technique and maintenance of the bit.

Next, when the UNC doesn’t dispense accurate results, it needs replacement. That indicates your tool is either faulty due to misalignment or wear. Consequently, a misaligned bit means the shaft is not straight and won’t deliver good results.

Under nail drill bit producing vibrations also needs a replacement. Vibrations will practically bring discomfort to a client’s finger. Plus, it will not deliver befitting results.

What Nail Bit Should You Use on Natural Nails?

Technicians will try to use ceramic, diamond, or tungsten carbide bits on natural nails. However, the tech should apply proper care and slow speed with such bits.

Moreover, a medium grit may try to help in such situations. Nonetheless, we highly prohibit using the tools on natural nails.

A sanding band and sanding caps with a Mandrel present some of the ideal tools to prepare natural nails. The devices work softly and will not cut or burn the natural nail like the ceramic, carbide, or diamond tools.

Synthetic rubberized bits also will allow soft application when used to prepare natural nails. You’ll use them safely to cut extra cuticles from a nail plate, buff your nails, or clear ridges.

What is a Good Indicator of a Properly Mounted Under Nail Drill Bit?

Various electric machines require distinct mounting procedures. Some, for instance, need tools for installation while others don’t. So, it depends on the device you choose for the UNC.

Before installing the under nail drill bit, it is proper to pass through the manual. The manual essentially gives complete instructions for mounting the bits.

An adequately mounted bit should offer a smooth application free from vibrations.

With the increasing need for modern bits in the nail and beauty industry, Syndent has managed to satisfy them all. The introduction of drill bits for nail machines and a volcano nail drill bit present some of the tools.
