Wet core drilling relies on a continuous water feed to cool the bit and suppress silica, making it the go-to for dense materials and larger-diameter holes. Dry core drilling runs without water, so it’s better for softer masonry or locations where water isn’t practical. Wet cuts create a water-and-debris slurry that needs containment and disposal, whereas dry cuts generate fine dust that must be captured with a dust-extraction system or managed with appropriate PPE.
