Ball bearing guides determine how easily and accurately the bit follows the workpiece or template. Top or bottom-mounted bearings allow for versatile routing from above or below, while some bits feature interchangeable bearings for varied cut widths. For instance, Bosch 85680M uses a top-mount bearing for template work, while the Amana Tool 49340 comes with multiple bottom-mount bearings for adjustable rabbets. Having access to various guide types and mounts increases your project flexibility, and a range of options are available to suit different routing techniques.
