The Festool HW R3-OFK 500 roundover cutter is a carbide-tipped router bit made for rounding over edges on plastic edging and solid wood. This is a roundover router bit designed for edge profiling and finishing. Model Number: 490093. If you run an OFK 500 or OFKC 500 edge router and want a small, controlled radius for finished edges, this is the purpose-built cutter for that job.

Festool built this bit specifically for edge work, not general routing. The 27 mm cutter diameter and 3 mm radius make it a good fit when you want a subtle roundover instead of a heavy profile. That matters on trim pieces, finished panels, and edge-banded parts where too much radius can look sloppy or cut away too much material.

One of the important details here is the special hollow shaft cutter design. It fits directly on the spindle, which improves run-out accuracy. In plain terms, that means the bit tracks truer as it spins, and that helps produce a cleaner routing pattern. On edge work, small wobble shows up fast, so this is not a throwaway detail.

The cutter uses a Z2 double-cut design with two carbide cutting edges. That gives you longer working life than a basic single-edge setup and helps maintain consistent cut quality over time. If you are doing repeat edge finishing on cabinet parts, trim stock, or solid wood components, the extra durability matters because it reduces the need to swap or replace the cutter as often.

Festool also calls out the low installation height and flush ball bearing mount. The practical benefit is access. You can route in rebates or work on stacked panels more easily because the cutter sits lower and stays compact around the workpiece. That is useful when you are trying to clean up finished edges without the tool fighting the setup.

Another detail worth noting is the 5 degree run-out transition on the router blade, which is there to help protect the surface during the profile. On finished material, that kind of geometry matters because it helps the radius blend out more smoothly instead of leaving an abrupt edge.

Compatibility is straightforward. This Festool roundover cutter is sized for the OFK 500 and OFKC 500. It is meant for edge routing applications where the tool, cutter, and bearing relationship are designed to work together. Festool specifies that it comes without bearing ball, and installation is done easily with a screw.

This is a smart buy for cabinet installers, finish carpenters, shop woodworkers, and serious DIY users who already own the right Festool edge router and want factory-matched edge profiling performance. If your work is mostly edge banding, solid wood edging, and finish passes where a small clean roundover makes the piece look complete, this bit makes sense. If you need a general-purpose router bit for a wide range of routers, this is not that tool. It is a specialized cutter for a specific Festool edge-routing setup.
