1. Insert the bit securely into a compatible 3/32" nail drill handpiece.
2. Select an appropriate speed based on the service, grit, working area, and your experience level.
3. Use light, controlled passes in tight cuticle areas, sidewalls, or detail zones at low-to-medium speed with very light pressure.
4. Keep the bit moving continuously instead of holding it in one area.
5. Remove dust and inspect the nail and surrounding tissue frequently to avoid overworking the area.

Professional Tip: Use light pressure and let the diamond surface do the work, especially around the natural nail and cuticle area.

How to Clean Diamond Nail Drill Bits

• Remove Debris: Brush away nail dust, cuticle residue, and product buildup after each use.
• Wash Thoroughly: Clean the bit with warm water and an appropriate cleaning solution, paying attention to the textured diamond surface.
• Disinfect Properly: Fully immerse the reusable bit in a professional-grade disinfectant according to the disinfectant manufacturer’s recommended contact time.
• Rinse & Dry: Rinse if required and dry the working surface and metal shank completely before storage.
• Store Clean & Dry: Keep disinfected bits in a clean, dry container until the next service.

Check the textured surface for trapped debris and dry the bit completely before storage.

• Applying Too Much Pressure: Use light pressure to avoid over-filing the nail plate or irritating the skin.
• Holding the Bit in One Spot: Keep the bit moving to avoid overworking one area.
• Using the Micro Cone for Broad Surface Work: This bit is designed for precision, not large-area filing. Use it only in small detail zones where its compact shape provides an advantage.
• Working on Living Tissue: Work only on appropriate dry cuticle, dead skin, or nail-prep areas. Avoid healthy living skin.

What are diamond nail drill bits best used for?

Diamond bits are best for precise cuticle work, sidewall cleaning, natural-nail prep, smoothing, and finishing.

What is the difference between Coarse, Medium, and Fine diamond grit?

Each grit provides a different level of abrasion:

• Coarse: Stronger abrasion for stubborn dry cuticle and dead skin.
• Medium: Balanced abrasion for routine cuticle and sidewall prep.
• Fine: Gentler abrasion for natural-nail refinement and finishing.

What makes the Conical Micro / Inverted Cone useful?

The inverted cone concentrates the working area into a compact profile, making it especially useful for precise cuticle detailing and fine linear work.

Will this bit fit my nail drill?

It uses a standard 3/32" shank, making it compatible with most professional nail drills that accept 3/32" bits.

Can I use this bit on the natural nail?

Yes. Fine diamond grit is well suited to gentle natural-nail refinement and finishing when used by a trained user with light pressure and controlled speed.
