Dry diamond core drill bits with high standards and quality are designed for core drilling soft brick, masonry, and concrete building block. like the name suggests, can be used without water. For reinforced concrete and granite, please use wet core bits. The diameter size of diamond core bits for dry drilling is always small size cause there is no water for cooling heat in drilling, and there would be air slot for cooling and light-weight.
