Product details

The Heller concrete spiral drill bit set consists of seven high-quality drills specifically designed for drilling in concrete and stone. With an optimized carbide geometry, these drills offer a long lifespan and high efficiency. The set includes various diameters, allowing for a wide range of applications, from masonry to aerated concrete. The drills feature a cylindrical shank that ensures easy handling and compatibility with common drill machines. Thanks to the innovative head design with a wide outlet and the large-volume "Twinmax-G2" spiral, high drilling speeds are achieved. Additionally, the special hardness-blast technique provides high break resistance, enhancing the reliability and durability of the drills. This set is ideal for professional craftsmen as well as DIY enthusiasts who value quality and performance.
