The black-coated version of our core drills made from high-speed steel is particularly wear-resistant and has excellent heat hardness. As they can be used without cooling, the tools are also suitable for demanding applications such as overhead drilling.
Thanks to the heat-repellent coating, the service life of the core drills is extended by up to 30 percent. Further advantages include the 19 mm Weldon shank and the high-performance toothing with pre- and post-cutter.
The highest quality of our core drills are compatible with machines from ALFRA Rotabest®, BDS, Bux, Ruko, Magnetor, Euroboor, Universal, Nitto, Jancy, Hougen, Magtron, Promac, Rotabroach and all other drills with a Weldon mount.
