WET CUTTING DIAMOND STONE CORE BITS
Stone Core Bits are designed to drill clean, smooth holes through ceramic tile, marble and stone. These bits are recommended for wet use only. We have two types of DDB core bits, one fits into a standard drill and has an adjustable/removable pilot bit that is only for starting/centering the bit and must be removed before the hole can be completed. The other, (preferred by pro-contractors because it is much faster), fits onto a high speed angle-grinder 5/8”-11 threaded arbor. These bits were developed specifically for wet coring through stone; dry coring can be accomplished, but the life will be significantly reduced. Our DDB’s can also be used with many other types of materials like stucco, wonderboard and tile.
