A diamond concrete drill bit is required for concrete core drilling. The bits for these tools are essentially steel tubes impregnated with pieces of industrial diamond. This drill is mounted onto the drilling machine’s shaft and then secured to the structure you are drilling into.

Once the core drill has completed the drilling process, there will be a concrete “slug” — the core — inside the drill bit that you can extract from the hole. This is accomplished by the drill’s hollow center, so it keeps the slug inside that defined area until removal. The core or slug can usually be examined to assess the stability or strength of the structure.

Core drills can also cut through several other materials besides concrete, including porcelain tile, limestone, rock, granite, fiberglass and even ice.
