The Festool 491427 Zero Degree Horizontal Base MFK 700 is a router accessory for Festool edge routers. This is a router accessory designed for straight horizontal routing and precise edge banding trimming. Model Number: 491427. If you already use an MFK 700 or related compatible router for finish work, this base gives you a more controlled way to guide the tool along an edge.

What matters here is adjustment and accuracy. The fine-adjustment design helps you sneak up on the cut instead of taking off too much material in one pass. That is a big deal when you are trimming edge banding, because once you cut too far, the panel is not getting that material back. This base is built to help you stay tight to the work and keep results consistent from piece to piece.

The horizontal configuration is the reason to buy it. It is designed specifically for straight routing in that position, which makes it useful for edge work where tool balance and viewing angle matter. Compared to trying to force a general setup into this job, a dedicated horizontal base gives you better control at the edge of the panel and a cleaner finished look.

Festool also calls out that this base allows the use of bearing-less bits when used together with a feeler bearing set mounted to the MFK 700 router. For users doing more exact trimming work, that opens up more routing options without changing to a different router platform. In plain terms, it gives the MFK system more flexibility for detail-focused work.

Construction is listed as metal and plastic, which is what you want on an accessory like this. The body needs to stay stable and accurate, while the adjustment points need to be easy to handle. At about 0.2 lbs assembled weight, it does not add much bulk to the router, so you keep the light, controlled feel that makes edge routing easier in the first place.

This accessory makes the most sense for cabinet installers, finish carpenters, shop woodworkers, and serious DIY users who are already in the Festool MFK 700 system. If your work includes edge banding, laminate trimming, or other detail routing where straight, controlled cuts matter, this is a practical add-on instead of a gimmick.
