Features: Single-layer diamond coating, cost-effective

Lifespan: Shorter but ideal for precision work

 

2. Sintered Diamond Drill Bits

Best for: Granite, marble, reinforced concrete

Features: Multi-layer diamond grit, longer lifespan

Advantage: Can be re-sharpened for extended use

 

3. Vacuum Brazed Diamond Drill Bits

Best for: Fast drilling in hard stone and ceramics

Features: Stronger bond than electroplated bits

Use Case: Tile installers and stone fabricators

 

4. Segmented Core Drill Bits

Best for: Large-diameter holes in concrete and asphalt

Features: Segmented rim for better cooling

Common Uses: Plumbing, electrical installations

 

Diamond Core Drill Bits

Why Choose Diamond Over Carbide or Masonry Bits?

✅ Longer Lifespan – Diamonds are the hardest known material

✅ Smoother Cuts – No chipping or cracking in brittle materials

✅ Faster Drilling – Reduced friction and heat buildup

 

How to Use Diamond Drill Bits Safely

1. Use Water Cooling – Prevents overheating

2. Start at Low Speed – Avoids bit slippage、

3. Apply Steady Pressure – Let the diamonds grind, don’t force it
