Make precise circular cuts with your router. These guides help you cut arcs at a specific distance from a set point—they’re often used to create the rounded edges of a workpiece.

Style B guides include a baseplate that can mount to both fixed- and plunge-base routers. Securely tape the included pivot plate to the desired center point of your cut, then connect the pivot plate to the baseplate with the router guide. Once connected, the guide holds your router at the correct distance from the circle center. These guides can also be used to make straight cuts. An included adapter lets you attach a vacuum hose to control dust.
