Diamond bits are known for their precision and versatility. They feature a diamond-coated surface that ensures precise cuticle cleaning, gentle gel polish or callus removal, and intricate work. The advantages of diamond bits include minimal heat generation, reduced material sticking, extended lifespan, and better resistance to sterilization.

Here are important sub-types of Diamond bits we should highlight: 

Cool Groove Diamond Bits

These diamond bits feature non-standard cross cuts on the surface with a depth of 0.1 mm. The unique cuts facilitate better air circulation, dissipating heat and preventing overheating of the treated surface. Benefits of cool groove diamond bits include improved heat dissipation, sharper cutting for precise nail shaping, longer lifespan, and exceptional durability due to the hexagonal diamond coating.

Coated Diamond Bits

Coated diamond bits offer the advantages of both diamond bits and a special coating, enhancing their performance and durability. These bits are designed to minimize overheating during work and reduce material sticking to the bit surface. The coating provides three times longer lifespan compared to standard diamond bits and better resistance to the sterilization process.

The 5-in-1 carbide bits offer multiple functions in a single bit, such as cleaning, preparing the nail bed, shaping, shortening, and smoothing the nail surface. Coated carbide bits provide benefits like minimal heat generation, faster removal of gel and acrylic, reduced material sticking, longer lifespan, and better resistance to sterilization.

Clean E-file Nail Drill Bits

To ensure proper hygiene and longevity of reusable nail drill bits, it is important to clean them after each client. The cleaning methods may vary depending on the material of the bit, so be sure to follow the instructions provided.

Here is an example of the cleaning process for diamond bits:

    1. Wash all bits thoroughly with soap and water, special brushes are recommended
    2. Clean bits with a brush and disinfectant solution (at least 70% alcohol is recommended)
    3. Sterilize bits in an autoclave or chemical sterilizer
    4. Dry bits completely before storing

    Safety Precautions when Working with Nail Drill Bits

    To ensure safe and effective use of nail drill bits, follow these guidelines:

    • Ensure that the speed does not exceed the recommended limits for the bit's shape and material.
    • The technician should have both elbows supported on the table surface. Working with the drill unsupported is not recommended.
    • Limit the contact of the bit with the nail plate to a maximum of 3 seconds, and maintain smooth and gliding movements.
    • Move the bit in the direction of its rotation to prevent it from slipping.
    • Keep the drill and bit as parallel as possible to the table surface. When reaching difficult areas, rotate the client's finger instead of the drill.
    • Always turn off and store the drill with the bit inserted or using a special cover.

    If you notice any unusual vibrations or odors, immediately turn off the drill.
