Centre bit is a tool used to create a circular hole in wood-based materials. It features a sharp point in the center, which helps to start the hole, followed by a larger cutting edge that removes material in a circular pattern. There are several synonyms for centre bit, including dowel bit, Brad point bit, twist drill bit, spur bit, and lip and spur bit. These alternative names typically reflect the specific design elements or usage of the tool. However, regardless of the name, center bits are an essential tool for woodworking and are available in a range of sizes for various applications.
