A chamfer bit is a router bit used to create a bevel on the edge of a piece of wood. Chamfer bits are commonly used for decorative purposes, such as creating a beveled edge on a countertop or table top. They can also be used for functional purposes, such as creating a chamfered edge on a piece of wood that will be exposed to the elements. Chamfering the edges of wood can help to improve its strength and reduce chipping.
