Ideal for creating large-diameter holes with speed and precision, the 230 mm Diamond Core Drill is designed for wet drilling with a drill rig. It cuts through demanding materials like heavily reinforced concrete, thick refractory walls, and hard natural stone. The drill features laser-welded diamond segments for durability and an aggressive, long-lasting cut. The robust barrel ensures straight, accurate holes, while the 1 1/4" UNC female backend is the industry standard for professional core drill motors.
