    More about this range

    Whether you're working on reinforced concrete, concrete, or other hard materials, our diamond core drill bits and core drill sets deliver superior performance. Our bits are crafted in collaboration with leading manufacturers in the diamond industry.

    Diamond core drill bits are essential for creating clean, circular holes in tough materials. With options for both wet and dry drilling, they adapt to various job site conditions. For optimal results we recommend wet drilling when working with extremely hard materials like marble or reinforced concrete.

    Choose your machine from our diamond core drills, or the full core drilling equipment range including stands and rigs. If your machine's thread does not match the bit, our core drilling adapters remove that limitation. Drilling dry indoors? Fit a dust extraction unit.
