Bearing type and position determine how the flush trim router bit follows a template and affect versatility. Lower ball bearings, as in the Timberline 190-26 and Amana Tool 47105, are great for standard template work, while upper ball bearings, like on the Amana Tool 47228 and Amana Tool 45460-3TS, enable pattern routing with the template on top. Some miniature bearings, such as on the Amana Tool MR0102, are perfect for tight curves. With various bearing positions and types, you can select a bit tailored to your routing setup and project style.
