Precision boreholes: The four-flute gear design maximizes material removal per revolution, delivering consistent drilling results in concrete and masonry without performance loss. Material efficiency: A precision-ground tip with wear protection reduces friction heat, extends bit life, and yields clean bore surfaces in mineral substrates without premature dulling. Stability control: A non-slip cross-angle drill tip ensures precise execution for metal and masonry drilling, ideal for demanding applications. Project-oriented design: Seven precisely calibrated diameters enable material-specific drilling without chipping, covering tasks from electrical installations to mounting work. Use scenarios: - Electrical installations: drill clean, accurate holes in concrete or masonry walls to route cables and install boxes. - Mounting and fixtures: create anchor holes for brackets, frames, shelves in brick or concrete walls. - Renovation and mixed-material work: perform precise holes for metal hardware in mineral substrates during retrofits, reducing the need for rework.
