Adamas core drills are the ideal choice for drilling in hard materials such as concrete, stone or asphalt. Our core drills, also known as diamond drills, concrete drills or core bits, are available in different sizes and for various applications. You can also choose from a wide range of wet and dry drills.

Buy concrete core drill

At Adamas you can buy high quality custom made core drills. Our core drills have unique advantages such as: a better connection between the segment and the drill tube due to the use of a ZigZag laser weld (for drilling up to Ø300 mm), which also ensures vibration-free working and easy removal of the core. The unique castellated shape also makes it easier to use (both when drilling by hand and with a drill rig). Because we use diamond grains of different sizes, we ensure a higher drilling speed and a longer life of the drill bit.

Diamond core drills from Adamas

Since 1978, Adamas has been offering the perfect solution for every drilling job in concrete, stone or asphalt. Since we produce all our core drills in-house and have a large stock, we can supply core drills with diameters ranging from Ø8 mm to Ø1200 mm quickly (usually within one working day). If a standard core bit has not the right size for your project, we can customize a drill tube and braze or laser weld a set of diamond core drill segments to suit your specific needs. Our product range includes thin wall diamond drills, thick wall diamond drills, socket drills and tile drills.
