Diamond Drill Bit: A Guide to Buying the Best Product for Your Project
The diamond drill bit is a fundamental tool for making precise holes in materials of varying hardness, such as reinforced concrete, masonry, natural stone and bricks. Choosing the right product is crucial to obtaining the desired results: a clean hole, quick to make and with a good tool life. In this purchasing guide we will analyze the main aspects to evaluate and present the models of diamond drill bits offered by La Nord: FORLD And FORLD300 for dry coring, and FORK for wet coring.
1. Features to Consider Before Buying Your Diamond Drill Bit
Material to be drilled
The diameter of the drill bit must be selected based on the size of the hole required. There are drill bits of various diameters to meet different needs:
- Small holes (up to 50 mm) : ideal for passing small cables or pipes.
- Medium holes (50-150 mm) : perfect for more complex system interventions, such as hydraulic pipes or medium-sized ducts.
- Large holes (over 150mm) : Used in heavy construction projects, for large system installations.
Depth of the hole
In addition to the diameter, it is important to consider the required depth:
- Standard length : sufficient for most plant applications.
- Extra length : needed for drilling through thick walls or when there are multiple layers of different materials.
Attaching the core drill to the diamond drill bit
- Each core drill has its own attachment system (e.g. 1 1/4″, M16, SDS, etc.). Before purchasing a diamond core bit , make sure that the core bit attachment is compatible with your core drill or that suitable adapters are available. This will avoid assembly problems and ensure excellent stability during drilling. thick or in the presence of multiple layers of different materials.
- If you don't find the right adapter available, Nord can offer you a wide range of adapters and extensions.
2. Dry or wet diamond crowns?
Another decisive factor is the choice between dry coring And wet coring . Both methods have specific advantages:
-
Dry coring
- No use of water, ideal in contexts where it is not possible to wet the work area.
- A dust extraction system is required to keep the environment clean and protect the operator.
- Particularly suitable for masonry, bricks and porous materials.
-
Wet coring
- Using water to cool the diamond segments, reducing the risk of overheating and wear.
- Less dust dispersion thanks to the action of water.
- Indications for use especially on hard materials such as reinforced concrete, concrete, natural stone.
3. The La Nord diamond drill bit for dry and/or wet coring

Diamond Drill Bit FORCA
- Designed for use with water, perfect for reinforced concrete, concrete and stone materials such as granite.
- Diamond segments are made with a specific formula to resist overheating and premature wear.
- Ensures precise holes, with reduced dust production and long tool life.
4. Conclusions
Buy the diamond drill bit most suitable for your project means carefully analyzing the characteristics of the material to be drilled, the size and depth of the hole, as well as the compatibility with the core drill in use. The choice between dry and wet core drilling completes the picture, allowing you to identify the ideal product to work safely and efficiently.
The North offers specialized solutions to meet every need:
- FORLD And FORLD300 for those who prefer dry coring.
