Tungsten Carbide Rounded Cylinder Bit – Medium (Blue) Fréza pro NailArt

Tungsten Carbide Rounded Cylinder Bit – Professional Removal and Refinement of Nail Enhancements

The Tungsten Carbide Rounded Cylinder Bit – Medium (Blue) is a professional rotary tool featuring a narrow cylindrical cutting head, a rounded tip and medium-grit cutting teeth. It is primarily designed for removing old artificial nail enhancements, gel polish and refining sculpted nails during infill services or shape adjustments.

Thanks to its narrow cylindrical shape, it allows controlled guidance and more precise work on smaller areas. The rounded tip makes it easier to work near the edges of the enhancement, where careful handling and the correct working angle are particularly important.

The blue marking indicates medium grit. Compared with the finer red version 5457, this drill bit has coarser cutting teeth, making it suitable for more effective material removal.

Key Features and Benefits

• Tungsten carbide construction – designed for professional shaping and removal of nail enhancement materials.
• Medium grit (blue marking) – enables effective material removal with controlled tool guidance.
• Narrow cylindrical head – suitable for precise work and smaller areas.
• Rounded tip – makes it easier to guide the bit near the edges of nail enhancements.
• Versatile application – removing old enhancements and gel polish, shortening and refining sculpted nails.
• Underside refinement – suitable for working on the underside and final shape of artificial nails.
• Coarser cutting teeth than the red version 5457 – suitable for more intensive removal of artificial material.

When to Use This Drill Bit

The tungsten carbide drill bit with a rounded cylindrical head is particularly suitable for:

• removing old artificial nail enhancements during infill services,
• removing gel polish from the surface of sculpted nails,
• gradually reducing the thickness of artificial enhancement material,
• refining the surface and shape of nail enhancements,
• shortening sculpted nails,
• refining the underside of artificial nails,
• carefully treating hardened skin around the nail at reduced speed, only with appropriate professional experience.

Important: This drill bit is primarily designed for working on artificial materials. Extra care is required when working close to the natural nail or skin. Although the rounded tip makes the tool easier to guide, it does not eliminate the risk of injury.

Recommended Application

1. Drill bit inspection: Before use, check that the bit is clean, the cutting teeth are undamaged and the shank is straight.
2. Correct fitting: Insert the 2.35 mm shank into the nail drill handpiece chuck according to the manufacturer's instructions and check that it is securely fitted.
3. Speed adjustment: Adjust the rotation speed according to the material being worked on, the technique used and the operator's experience. Do not exceed the maximum permitted speed of 25,000 RPM.
4. Material removal: Guide the drill bit using smooth, controlled movements without excessive pressure. Regularly check the amount of material remaining.
5. Shape refinement: When shortening or refining the underside of the enhancement, take into account the shape and structure of the artificial nail.
6. Working in sensitive areas: Take particular care when working close to the natural nail and skin. When treating hardened skin, use reduced speed and only techniques appropriate to your professional experience.
7. Finishing: If necessary, use a suitable finer-grit tool for delicate final refinement.

Cleaning and Maintenance

Regular cleaning and proper maintenance help preserve the working performance of the drill bit, reduce clogging of the cutting teeth and support safe use in a professional nail salon.

1. Mechanical cleaning: After use, remove dust and material residue from the cutting teeth with a suitable cleaning brush. For heavier build-up, carefully use a brush specifically designed for cleaning metal drill bits.
2. Disinfection: Treat the tool with a disinfectant suitable for metal rotary instruments. Follow the disinfectant manufacturer's instructions regarding concentration, contact time and application.
3. Rinsing and drying: If required by the disinfectant manufacturer, rinse the drill bit and dry it thoroughly.
4. Sterilisation: If the tool is suitable for dry heat sterilisation according to the manufacturer's instructions, do not exceed 180 °C and follow the prescribed sterilisation procedure.
5. Inspection and storage: Before the next use, check that the drill bit is clean, dry and undamaged. Store it in a way that prevents damage to the cutting teeth and recontamination.

Important: Mechanical cleaning, disinfection and sterilisation are separate procedures. Removing dust alone does not replace disinfection or sterilisation where required. Exceeding 180 °C during dry heat sterilisation may reduce the hardness of the cutting teeth and shorten the service life of the tool.

DENATO Professional Recommendation

When working with a tungsten carbide drill bit, the correct rotation speed, smooth guidance and light pressure are more important than applying force to the working surface. Excessive pressure may cause the material to heat up, overload the nail drill motor and handpiece chuck, and accelerate wear of the tool.

For more effective removal of artificial material, the medium grit of the blue version can be used. If finer work or more delicate shape refinement is required, switch to a finer-grit drill bit, such as the red version 5457.

Do not hold the rotating drill bit in one place for too long. Regularly inspect the condition of the cutting teeth and discontinue use of damaged, worn or deformed tools.

Material & Safety

Material: Tungsten carbide (hard metal).

For professional use only. Use the drill bit exclusively with a compatible electric nail drill and an appropriate chuck mechanism. Before each use, check the condition of the tool and ensure it is securely fitted.

• Do not exceed the maximum speed of 25,000 RPM.
• Secure the shank according to the nail drill manufacturer's instructions and check that it is properly fitted before switching on the device.
• Do not use damaged, bent or unbalanced drill bits.
• Work without excessive pressure and do not hold the rotating tool in one place for an extended period.
• Take particular care when working close to the natural nail and skin.
• When treating hardened skin, use reduced speed and work only within the limits of your professional experience.
• Use suitable dust extraction and personal protective equipment.
• Ensure appropriate cleaning and hygienic treatment of the tool after each use.
• During dry heat sterilisation, do not exceed 180 °C and follow the manufacturer's instructions.
