Ideal for creating medium-to-large holes in reinforced concrete, refractory brick, and hard stone, the 80 mm Diamond Core Drill is designed for wet drilling with a drill rig. It features laser-welded diamond segments for durability and a fast, clean cut through tough materials. The drill's heavy-duty barrel maintains straightness, while its 1 1/4" UNC female thread provides a secure connection to professional rig-mounted core drilling systems.
