Core Drill Bits are specially designed cutting tools used to remove a cylindrical shaped material that is left inside the drill bit called the core. Coring bits are available in different types that can be used in a wide range of materials like concrete, metal, glass, ceramics, and more. Diamond core bits have diamond cutting tips that are suitable in cutting hard materials. Additionally, core drills can be differentiated as wet and dry bits. Wet bits are used with water to aid in cutting while dry bits can be used without water. Core drill bits are available in different sizes and sets.
