Diamond core drills are designed for core drilling in the construction industry. They are used for drilling deep holes of various diameters (especially large ones) in extremely hard materials such as stone, reinforced concrete, brick, hollow bricks, asphalt or stoneware. They are suitable for dry and wet drilling in concrete. They allow for through drilling. An example of such use is drilling holes adapted to pipes. Diamond core drill makes work easier, faster and more precise. The use of diamonds in the production process ensures maximum resistance of the drill to mechanical damage and wear, which translates into its much longer service life. Diamond core drills are designed for multiple use. They maintain functionality even after dozens of uses. Importantly, the use of core drills for concrete does not require prior impact or drilling of the drilled material.

Diamond core drills differ in terms of diameter and number of diamond segments. These parameters should be adjusted to the size of the hole to be drilled. Our assortment includes core drills with diameters from just 4.3 mm to as much as 20 mm, designed for processing various materials. You can easily match the product to the planned application. In addition, core drills should be characterized by high rotational speed and increased resistance to wear.
