Diamond drill bit D-10*4.0 size head 4.0x3.8 mm

Ball-shaped Diamond Nail Drill Bits, designed for precise cuticle work and nail surface treatments. They are crafted from premium diamond and stainless steel for long-lasting durability and precision. These versatile bits cater to a variety of nail care needs, from removing dead cuticles to polishing for a flawless finish.

Variants and Uses:

• Medium (Blue) and Coarse (Green):
  These bits are ideal for removing dry, dead cuticles effectively. Featuring a more abrasive surface, they are perfect for the initial phase of cuticle removal, ensuring smooth and clean results.
• Fine (Red) and Extra Fine (Yellow):
  Designed for finishing and polishing, these bits gently smooth the cuticle zone and refine the nail surface. Their less abrasive texture is ideal for achieving a sleek, professional finish.

Maintenance:

Maintaining hygiene and prolonging the life of your diamond drill bits is essential. After each use:

• Wash, clean, sterilize, and dry the bits thoroughly.
• Use a disinfectant solution containing at least 70% alcohol for effective sterilization.
  These steps are crucial for preventing the spread of infections and ensuring the safety of your tools.
