Collection: Diamond Core Drill Bits for Concrete & Stone | Distar USA

Diamond core drill bits are designed for drilling clean, precise holes through concrete, masonry, stone, and other hard construction materials. Unlike standard drill bits, core drills remove a cylindrical section of material, allowing for faster, more efficient hole creation with minimal damage to surrounding surfaces.

This collection includes professional-grade diamond core bits engineered for both wet and dry drilling applications. Wet core drilling uses water to cool the bit, reduce dust, and extend tool life, making it ideal for deep or reinforced concrete drilling. Dry core bits are better suited for quick, shallow applications where speed and convenience are prioritized.

Core drills are commonly used for installing plumbing lines, electrical conduits, HVAC systems, and anchors in concrete and masonry structures. High-quality diamond segments allow these tools to cut through tough materials—including reinforced concrete with rebar—while maintaining accuracy and durability under heavy use.

Distar core drill bits are built for professional contractors who require reliable performance, long service life, and precise results across demanding jobsite conditions. Designed for compatibility with standard core drilling equipment, these tools deliver consistent cutting efficiency across a wide range of diameters and applications.

Available in multiple sizes and configurations to match your drilling needs. Pair with Distar diamond blades, grinding cups, and surface preparation tools for a complete cutting and drilling system.
