Bases support a compatible router motor, set the cutting depth, and dictate the types of cuts the router can make. The base type determines the accuracy of the cut, how the bit enters the workpiece (from the top or at the edge), and whether the bit can move up or down while cutting.

Router guides supply a template or set a path that routers follow to produce cuts of a specific shape or placement. They are used for applications such as creating curved slots and insets, routing cutouts for door hinges, or forming grooves parallel to workpiece edges.

Dust collection accessories for routers gather wood chips and dust and direct them into a dust extractor to prevent debris from spraying out and settling on equipment and surfaces in the workspace. They fit specific router brands and models.
