What is a Core Bit?:
Drill bits are cutting tools used to create or increase cylindrical holes. They are held in a drill to rotate them, which provides torque and axial force to create a hole in the material you’re drilling. A core drill bit can be used to enlarge an existing hole. The name comes from its first use, for drilling out the hole left by a foundry core, a cylinder placed in a mould for a casting that leaves an irregular hole in the product. A core drill bit is similar to a reamer as they don’t have a cutting point or means of starting a hole. They have 3 or 4 flutes which enhances the finish of the hole and ensures the bits cut evenly. Tungsten carbide and other carbides are extremely hard materials that can drill in virtually all materials. Due to their brittleness they are mainly used for drill bit tips, small pieces of hard material fixed or brazed onto the tip of a bit made of less hard metal.
