Nail drill bits

Choosing the right drill bits

Understand diamond and carbide, shapes, grits and handpiece compatibility.

What is the difference between a diamond bit and a tungsten carbide bit?

A diamond bit works precisely around the cuticles, sidewalls and small areas of keratinised skin. A tungsten carbide bit removes artificial materials such as gel or acrygel more efficiently. The right choice therefore depends on the area, the material and the required level of abrasiveness.

Which bit should I choose for working on cuticles?

To lift and clean around the nail, choose a fine diamond bit suited to the area: a flame for the proximal fold and sidewalls, a ball for gently removing small pieces of skin, or a needle for narrow areas. Start with a fine grit, light pressure and a controlled speed. Discover the diamond bit collection.

Which bit should I use to remove gel or acrygel?

For removing gel or acrygel, a tungsten carbide bit with suitable teeth and grit is generally the most effective. A medium grit is often appropriate for routine work, while a more abrasive grit speeds up bulk removal on a thick enhancement. Never work down onto the natural nail plate with a bit that is not designed for that purpose.

Which bit should I use to remove gel polish?

Gel polish can be removed with a bit suited to the product and your skill level, often a fine carbide or ceramic bit depending on the available references. Work in smooth passes without excessive pressure, leaving a thin base layer if necessary to protect the natural nail. Check the specifications of each bit and follow your professional protocol.

What do the grit colours on bits mean?

The colour code generally indicates abrasiveness: yellow for extra fine, red for fine, blue for medium and green for coarse. Some ranges also use purple or black for higher levels. The exact correspondence can vary by material and manufacturer, so always check the grit shown on the product page before use.

How do I choose the shape of my nail bit?

Each shape is designed for a specific action: flame for folds and cuticles, ball for small pieces of skin, cone or rounded cone for preparation and smoothing, barrel for reducing a material surface, and needle for fine areas. Choose the use first, then the size and grit. Bit sets combine several complementary shapes.

Can a carbide bit be used on the natural nail?

As a general rule, carbide bits intended for removing artificial material should not be used directly on the natural nail plate. Their cutting power can thin it very quickly. Use only a reference that the manufacturer explicitly states is suitable for this purpose, with the appropriate technique. If in doubt, choose a gentler bit and ask our team for advice.

Are there bits designed for left-handed users?

Yes. Carbide bits may have right-cut, left-cut or reversible teeth. A left-handed reference cuts effectively when the nail drill rotates in the direction suited to the working hand. Check the rotation direction on the product page; diamond bits, which abrade rather than cut with teeth, are generally less dependent on this criterion.

Are OnglyCare bits compatible with every nail drill?

Most professional bits offered use a standard 2.35 mm shank, also known as 3/32 inch. They are compatible with handpieces that accept this diameter, including many professional models. However, check the diameter required by your nail drill and the bit’s product page before purchasing: compatibility does not depend on the brand alone.

Which bit set should a beginner choose?

To get started, look for a set that matches your services: a few fine diamond bits for the cuticles, a ball, a flame and a removal bit suited to the materials you use. A small, well-understood selection is better than many redundant shapes. Compare our nail drill bit sets or contact us for personalised advice.

Professional practice

Use, hygiene and care

Adjust speed, prevent overheating and follow a suitable protocol for each instrument.

What speed should I use with a nail bit?

There is no single speed that is suitable for every bit. It depends on the shape, diameter, grit, material being worked, nail drill and your technique. Follow the manufacturer’s recommended range, start gradually and keep the bit moving. High speed never compensates for excessive pressure or poor technique.

Why does the bit become hot during removal?

Heat is often caused by excessive pressure, holding the bit in one place, an unsuitable speed, or a worn and clogged bit. Work with smooth passes, let the tool cut without forcing it and check its condition. If the client feels heat or pain, stop immediately and adjust the setting or technique.

How can I tell whether a bit is worn?

A worn bit removes material less effectively, requires more pressure, becomes hotter or leaves an uneven result. On a diamond bit, the coating may appear smoother; on a carbide bit, the cutting edges may be blunt. Replace any bit that is bent, corroded, damaged or vibrates abnormally.

Why does my bit vibrate in the handpiece?

Vibration can be caused by a bent shank, an incorrectly inserted bit, a dirty chuck, excessive speed or a handpiece that needs servicing. Stop the device, inspect the shank visually and reinsert the bit correctly. Do not use a bent bit: it may damage the handpiece and make your work imprecise.

How should bits be cleaned, disinfected and sterilised?

These are three separate stages: cleaning removes visible residue, disinfection reduces microorganisms, and sterilisation follows a validated protocol for compatible equipment. Follow the manufacturer’s instructions and the product’s concentrations and contact times, then dry the instruments completely. Applicable requirements also depend on your activity and local regulations.

Does an ultrasonic cleaner sterilise instruments?

No. An ultrasonic cleaner makes cleaning easier by loosening residue in hard-to-reach areas, but it does not replace disinfection or sterilisation. After the cycle, rinse if required by the product protocol, dry thoroughly, then continue with the steps suited to the material and the manufacturer’s instructions.

Can all bits and tools be autoclaved?

No. Autoclave compatibility depends on the material, coating and manufacturer’s instructions. Some professional steel instruments or bits are designed for sterilisation, while others may be damaged. Always consult the product page or instructions and never autoclave an accessory that is not identified as compatible.

How should bits be stored after hygiene treatment?

After suitable cleaning and treatment, dry the bits completely to prevent corrosion and deposits. Store them in a clean, dry, closed holder, clearly separating treated equipment from used equipment. If your protocol includes sterilisation in pouches, keep the packaging intact until use and observe its validity period.

Professional equipment

Choosing and maintaining a nail drill

Speed, torque, ergonomics, maintenance and signs that require after-sales support.

How do I choose a professional nail drill?

Above all, assess the torque, stability at working speed, handpiece comfort, vibration, noise, direction of rotation and availability of after-sales support. Maximum speed alone is not enough. For intensive use, choose a machine designed for professionals with a balanced handpiece. Compare our professional nail drills.

What is the difference between speed and torque on a nail drill?

Speed is the number of revolutions per minute. Torque is the machine’s ability to maintain rotation when it meets resistance. A nail drill may advertise a high speed yet slow under load if its torque is low. For consistent, comfortable work, look for a balance between speed, torque and handpiece quality.

Should I choose a 30,000 or 50,000 rpm nail drill?

A good-quality 30,000 rpm nail drill covers many manicure services. A model capable of 40,000 or 50,000 rpm can offer more reserve power, but this does not mean that you should work at its maximum speed. Torque, stability, vibration and control of your technique remain more important than the highest number.

How can I recognise a comfortable and reliable handpiece?

A good handpiece is well balanced, sits naturally in the hand and remains stable without excessive vibration. Its locking system must hold the bit securely. A slight rise in temperature may occur during use, but significant heat, a new noise or persistent vibration means you should stop and check the equipment.

How should I maintain a nail drill and prevent dust build-up?

Switch off and unplug the nail drill before maintenance. Regularly remove dust from accessible openings and the handpiece surface according to the instructions, without injecting liquid or compressed air into the mechanism unless the manufacturer allows it. Use suitable dust extraction during services and follow the recommended maintenance intervals.

What warranty and after-sales support apply to a nail drill purchased from OnglyCare?

Coverage depends on the model, manufacturer, purchase date and whether you are a professional or consumer customer. Keep your proof of purchase and avoid any unauthorised opening or repair. If a fault occurs, contact OnglyCare after-sales support with the reference, order number and a precise description of the problem to receive the appropriate procedure.

Precision instruments

Everything about STALEKS tools

Scissors, nippers, pushers, files and PODODISC: choose the right instrument and preserve its precision.

Which STALEKS tools are available from OnglyCare?

The STALEKS collection includes professional manicure and pedicure instruments: cuticle scissors, nippers, pushers, curettes, files, rasps, PODODISC holders and discs, and accessories. Use the collection filters or search for the exact reference to find the appropriate shape and size.

What is the difference between the STALEKS SMART, EXPERT and EXCLUSIVE ranges?

STALEKS organises its professional tools into several series. SMART offers functional references for regular work, EXPERT provides technicians with a very wide choice of shapes and sizes, and EXCLUSIVE stands out through premium finishes and designs. The series is not the only criterion: compare the geometry, blade length, size and stated use above all.

How do I choose between STALEKS scissors, nippers and a cuticle pusher?

Scissors are suitable for precise cuticle trimming when their curve and length match your technique. Nippers offer a different grip and can be selected according to jaw length. A cuticle pusher is used to lift and push back before cutting. For pedicures, PODODISC systems serve other purposes. Choose each tool according to your technique, hand and service.

Why are STALEKS tools popular with professionals?

STALEKS professional ranges are recognised for their medical-grade stainless steel, precise geometry and the hand finishing of many cutting edges. The numerous shapes and sizes allow the tool to be matched to the technique and hand shape. Its service life then depends on correct use, maintenance and professional sharpening.

How should a STALEKS tool be cleaned, disinfected and sterilised?

Follow the instructions for the reference and your professional protocol: thoroughly clean away residue, rinse if necessary, dry, disinfect with a compatible product, then sterilise when required by the instrument and regulations. Observe concentrations, temperatures and contact times. Do not leave a metal tool damp and avoid products that may attack the steel.

Can STALEKS scissors or nippers be resharpened?

Yes. Many professional STALEKS instruments are designed to be maintained and resharpened. Entrust this operation to a specialised service that preserves the original geometry; improvised sharpening can damage the blades or jaws. Between services, protect the tips, keep the tool completely dry and avoid impacts.

How do I check a STALEKS reference before purchasing?

Compare the series name, product code, blade length or shape, jaw size and stated use on the product page. References displayed as STALEKS on OnglyCare are sold as products of the brand. If two models appear similar, send us their links: we can help you distinguish their features before ordering.
