A dovetail router bit is a specialized cutting tool used in woodworking to create dovetail joints, which are used to connect two pieces of wood at right angles. The router bit has a cutting edge that is shaped like a dovetail, with angled sides that create a wedge-shaped groove when the bit is used to cut into wood.
Dovetail joints are often used in furniture making and cabinetry, as they provide a strong and durable connection between two pieces of wood. The joint is created by cutting a series of interlocking grooves and slots into the wood using a dovetail router bit and then fitting the pieces together like a puzzle.
There are different types of dovetail router bits available, each with its own specific shape and cutting angle. Some common types include straight dovetail bits, angled dovetail bits, and variable angle dovetail bits. The type of bit you choose will depend on the specific application and the type of joint you want to create.
