As wall tiles are becoming larger and harder, drilling holes with a tile drill is becoming increasingly difficult. For this reason, Bosch has developed the Expert Hard Ceramic Drill, which allows you to drill hard ceramics dry. It is also significantly more durable than our benchmark tile drill. This special hard ceramic drill utilizes Bosch's carbide technology. Carbide is the hardest of all metals. It is combined with an advanced multi-cutter tip that distributes the workload across several asymmetrical surfaces. This complex drill tip, manufactured using a fine-tuning production process, also enables precise starting without slipping or scratching.
