Once the hole is made, simply push the tool deeper to let the cone section enlarge, chamfer, and polish the edges. Do I need to add water when using this bit? No, water is not strictly required. It is manufactured with premium brazed diamond technology designed for direct dry use. However, adding water can help suppress dust, cool down the material, and further extend the tool's lifespan.
