Diamond Drill Cores

Wet & Dry Diamond Cores

We stock both wet diamond cores and dry diamond cores, each suited to different jobsite conditions and materials. Wet cores are ideal for drilling into concrete and reinforced concrete by providing cooling, dust suppression, and longer blade life. Dry cores are tailored for indoor or time-sensitive applications where using water is not feasible; they perform well in brick, block, and light concrete.

Product Variants & Connections

Our cores are available in a range of diameters and lengths, with multiple connection types (e.g. ½" BSP female, 1¼" UNC) to ensure compatibility with common core drilling machines.
