Why are B+BTec’s diamond drill bits so special?
B+BTec’s diamond drill bits stand out on multiple fronts. They offer both wet drilling in concrete and reinforced concrete, and dry drilling in hard materials such as masonry, calcium silicate brick, and clay brick. This versatility makes a B+BTec diamond drill bit suitable for a wide range of projects.
B+BTec supplies high-quality diamond drill bits for every job, from drilling through heavily reinforced concrete to precision work in masonry. Thanks to our expertise and innovative approach, you are guaranteed the right solution. Choose B+BTec and experience quality and precision in all your drilling projects.
What to consider when buying a diamond drill bit?
When choosing the right diamond drill bit, several factors are important:
- Diameter of the drill bit – depending on the desired hole size.
- Wet or dry drilling – wet drilling prevents overheating and extends the life of the drill bit, while dry drilling is suitable for jobs without water supply.
- Material type – concrete, reinforced concrete, stone, or tiles each require a specific drill bit.
- Machine connection – check the connection (e.g. 1/2” or 5/4”) to ensure the drill bit fits your core drilling machine properly.
Our specialists are happy to help you choose the right diamond drill bit.
High-quality features of our diamond drill bits
One of the most impressive features is the unmatched drilling speed. These diamond drill bits are up to twice as fast as conventional bits, especially in heavily reinforced and high-strength concrete. This means you save time and money without compromising on quality and precision.
Reinforced concrete can be a nightmare for standard drill bits, but not for a B+BTec diamond drill bit. They effortlessly drill through steel, allowing you to work more efficiently without worrying about obstacles in the material. This makes them ideal for projects where the presence of steel can be a challenge.
Approved for healthy and safe working by TNO
We have had all our drill bits approved by TNO for dust-free operation, meaning they are certified for up to 8 hours of drilling per working day. Dust-free working is not only more efficient but also much healthier and safer for those working on site. This guarantees not only a healthy working environment but also reduces the risk of health problems with prolonged use.
In addition, dust-free working ensures cleaner air on the construction site, protecting workers’ health. It also prevents dust from accumulating in machines, extending the life of the equipment. Furthermore, dust-free working helps reduce the ecological footprint of your project.

Frequently asked questions
What is the difference between wet and dry diamond drilling?
Diamond drilling uses water to cool the drill bit and prevent dust formation. This is ideal for concrete and reinforced concrete. Dry drilling is used for brickwork or when water is undesirable.
Which diamond drill bit do I need for reinforced concrete?
For heavily reinforced concrete, we recommend our TNO-approved wet drills. These drills efficiently cut through concrete and steel, with high speed and minimal wear.
How do I work dust-free when drilling?
Our diamond drills are approved for 8 hours of dust-free work per day. Use a dust extraction system for maximum workplace safety and health.
What are the applications of diamond core drills?
Diamond core drills are used for making precise holes in concrete, natural stone and masonry, for example for installations, pipes, anchor rods or ventilation shafts.
There is no difference between a core drill and a diamond drill. They are the same thing.
A core drill is a drill used to bore a circular hole (a core) from concrete, stone, or asphalt. A diamond drill is a type of core drill where the drill bit is fitted with industrial diamond segments. In practice, the terms core drill and diamond drill are often used interchangeably.
When do you use a diamond core drill?
A diamond core drill is used when you want to drill holes in hard materials such as concrete, natural stone, or asphalt quickly, precisely, and with minimal dust. Thanks to the diamond segments, the drill grinds through the material, ensuring a smooth result without cracks.
Is every core drill a diamond drill?
Not every core drill is a diamond drill, but every diamond drill is indeed a core drill. Core drill is the collective term, while diamond drill specifically denotes the type with diamond segments.
What is better: a core drill or a diamond drill?
For professional use in concrete and stone, a diamond drill bit is usually the best choice. It lasts longer, drills faster and delivers a cleaner result. A standard core drill without diamond is more suitable for softer materials or lighter applications.
What size diamond drill bit or core drill do I need?
The correct size depends on the application. For pipes or electrical conduits, for example, diameters between 32 and 82 mm are often used, while for large ventilation openings or penetrations, sizes up to 300 mm are needed.
