If you’re in the construction, renovation, or infrastructure industry, you already know how important it is to have the right tools—especially when it comes to drilling into tough materials like concrete, stone, and reinforced structures. That’s where Lizma Diamond Core Drill Bits come in.
These drill bits are engineered for unmatched durability, high-speed performance, and precise cutting, even in the most challenging environments. In this detailed guide, we’ll walk you through everything you need to know about Lizma’s diamond core drill bits, from features and materials to real-world applications and buying tips.
🧱 What Is a Diamond Core Drill Bit?
A diamond core drill bit is a special type of drill bit that uses industrial-grade diamonds at its tip or edge. These bits are specifically made for cutting through extremely hard surfaces like:
- Reinforced concrete
- Granite
- Marble
- Asphalt
- Brick
- Tiles
- Natural stones
Instead of crushing the material like regular drill bits, diamond core drill bits cut with precision, removing a cylinder of material and leaving a clean, round hole.

🧪 How Does a Diamond Core Drill Bit Work?
A diamond core drill bit works by grinding, not pounding, its way through tough material. The diamonds in the segment remove material layer by layer, resulting in:
- Smooth holes
- Minimal surface damage
- Less dust and debris
- Faster job completion
This makes them perfect for dry and wet drilling applications.

⚙️ Wet vs Dry Core Drilling: Which One to Choose?
💧 Wet Drilling:
- Uses water to cool the bit
- Reduces dust and heat
- Increases lifespan of the bit
- Ideal for concrete, reinforced materials
🌬 Dry Drilling:
- Doesn’t require water
- Suitable for smaller jobs
- Best for brick, tile, soft stone
Lizma Diamond Core Drill Bits can be used in both settings, depending on your project needs.
🧾 How to Choose the Right Diamond Core Drill Bit
There are a few factors to keep in mind when choosing your core bit:
1. Material You’re Drilling Into
- For concrete with rebar, go for high-grade diamond segments.
- For tiles or marble, a thinner bit with fine diamonds is ideal.
2. Drill Machine Compatibility
- Check your machine’s power and RPM. Lizma drill bits are compatible with most high-speed rotary and hammer drills.
3. Shank & Screw Type
- Ensure the shank type (e.g., Hex) matches your tool.
- Choose from Lizma’s screw options like 1-1/4-7, 1-1/4-3, or M22.
4. Bit Diameter and Length
- Select based on the hole size you need – we offer custom sizes for bulk orders.
🧼 Maintenance Tips to Increase Life of Your Drill Bit
Taking care of your tools ensures they last longer and perform better. Here are some tips:
- Always cool the bit during drilling (wet drilling recommended for tough jobs).
- Don’t force the drill – let the diamonds do the work.
- Clean the bit after use to remove debris.
- Store in a dry, cool place to prevent rust.
