The Carat Laser Diamantboor Ø121x400mm M30 is a professional-grade diamond core drill designed specifically for demanding concrete drilling applications. This Beton Master series drill features a 121mm diameter cutting head with a 400mm drilling depth capacity, making it suitable for creating large diameter holes in reinforced concrete, masonry, and other hard construction materials. The drill utilizes high-quality diamond segments permanently bonded to a steel core barrel, ensuring consistent cutting performance and extended service life. The M30 thread connection provides secure attachment to compatible drilling machines and stands. This diamond core drill is engineered for precision drilling in vertical, horizontal, and overhead positions, with laser-welded segments that maintain cutting efficiency throughout the drill's lifespan. The hollow core design allows for efficient dust and water extraction during wet drilling operations, while the optimized segment spacing prevents clogging and ensures smooth drilling progress. The drill's construction incorporates a reinforced steel body with a precision-ground outer surface for minimal vibration and accurate hole geometry. It is suitable for professional construction, renovation, and installation work requiring clean, precise holes for plumbing, electrical conduits, ventilation systems, and structural connections. The diamond-impregnated segments are formulated for optimal performance in concrete with varying aggregate sizes and reinforcement densities. This core drill maintains cutting sharpness through proper cooling and lubrication during operation, with the ability to penetrate rebar and other embedded metal elements without significant performance degradation. The tool is compatible with standard diamond drilling equipment and requires appropriate safety measures including eye protection, hearing protection, and dust control systems during operation.
