Advantages of Diamond Micro Drills

✅ High Precision – Enables drilling of extremely small holes (down to 0.1mm).

✅ Long Tool Life – Diamond grit provides exceptional wear resistance.

✅ Superior Surface Finish – No chipping or cracking in brittle materials.

✅ Versatile Applications – Suitable for metals, ceramics, glass, and composites.

✅ Minimal Heat Generation – Prevents thermal damage and stress fractures.

Types of Diamond Micro Drills

1. Electroplated Diamond Micro Drills

🔹 Best for: Glass, ceramics, gemstones, and composites.

🔹 Features: Single-layer nickel-bonded diamond grit ensures high precision.

🔹 Benefits: Provides fast material removal and smooth edges.

2. Sintered Diamond Micro Drills

🔹 Best for: Heavy-duty drilling in hard materials.

🔹 Features: Multiple layers of diamond grit extend tool life.

🔹 Benefits: Can be resharpened for longer performance.

3. Vacuum Brazed Diamond Micro Drills

🔹 Best for: High-speed drilling in metals, ceramics, and composites.

🔹 Features: Strong bonding of diamond grit to the drill bit.

🔹 Benefits: Extremely durable and heat-resistant.

How to Choose the Right Diamond Micro Drill

Factor Considerations Material Soft (e.g., glass) → Electroplated, Hard (e.g., sapphire) → Sintered Drill Size Choose a diameter as small as 0.1mm for precision applications Bond Type Nickel bond for precision, sintered bond for extended lifeCutting Speed Lower RPM for delicate materials, higher RPM for tough materials Lubrication Coolant or water is necessary to prevent overheating

Proper Usage & Maintenance Tips

✔ Use Coolant or Lubricant – Prevents overheating and prolongs tool life.

✔ Use the Right Speed & Pressure – Excess force can cause fractures in brittle materials.

✔ Perform Regular Cleaning – Remove debris buildup to maintain efficiency.

✔ Choose the Right Drill Machine – Ensure your machine supports high-precision micro-drilling.
