Flush trim router bits are specialized cutting tools used in woodworking to achieve precise and flush trims on the edges of a workpiece. These bits feature a cutting edge with a bearing that rides along the edge of a template or existing surface, ensuring a clean and accurate cut.

Flush trim router bits are commonly used to trim the edges of laminates, veneers, or overlapping materials, bringing them flush with the surrounding surface. They can also be used to duplicate the shape of a template onto a workpiece, allowing for precise replication of intricate patterns or curves.
