Core Drilling Machines

What is a core drilling machine?

A core drilling machine, also known as a diamond drill or concrete drill, is a specialized tool that allows you to drill precise round holes in extremely hard materials such as concrete, reinforced concrete, stone, or asphalt. Core drilling machines are often used in installation work, for example, when creating penetrations for gas pipes, electricity, or ventilation.

The unique feature of a core drilling machine is its drilling technique. Instead of completely pulverizing the material, as with a twist drill, for example, a core drill drills around the hole, leaving the central portion, the drill core, intact. This creates smooth, clean holes without excessive stress on the material. Thanks to this technique, core drilling is ideally suited for use in construction projects, technical installations, and renovations where precision is required.

What makes B+BTec core drilling machines so special?

Our Karat® Core Drilling Machines are designed for maximum performance and reliability. They feature powerful drill motors and a robust 3-speed gearbox, allowing them to effortlessly drill through various materials. Whether it's high-strength concrete, heavily reinforced concrete, or other building materials, our core drills deliver professional results under all conditions.

Flexible drilling for every application

Flexibility is essential on the construction site. Our Karat® core drill range includes options for both wet and/or dry drilling. Whether you're working in sand-lime brick, concrete, masonry, or brick, our core drills will drill effortlessly.

Suitable for intensive daily use

At B+BTec, quality is paramount. Our core drills are equipped as standard with powerful 2400W or 3200W drill motors and advanced electronics with LEDs and Pulse motor protection. For optimal safety, they are equipped with both an electronic and mechanical slip clutch. This combination makes our core drills suitable for intensive daily use, with minimal downtime and maximum protection for both the user and the machine.

Versatile, with or without a stand

Our Karat® core drills are suitable for both manual applications and use with a professional drill stand. Drilling with a stand offers optimal precision for larger drill diameters or deeper holes. Thanks to the modular design, you can easily switch between configurations, so you always work with the right setup.

What do MG and BG mean?

MG stands for Midgrip and BG for Backgrip. This indicates the location of the handle on the machine.

Expand with smart modules and accessories

With the right accessory, you get more out of your core drill. At B+BTec, it's not just about the core drill itself. We also offer a range of accessories, such as diamond drill bits for your core drill. With easy exchange of drill motors, drill stands, and accessories, you can quickly and efficiently switch between different tasks and materials. This not only increases your productivity but also ensures you have the right equipment for the job.
