Festool HW R6-OFK 500 Roundover Cutter is a router bit made for edge rounding on plastic and solid wood. This is a roundover cutter designed for rounding and finishing exposed edges. Model Number: 490096. If you are running an OFK 500 or OFKC 500 edge router and want a clean 6 mm roundover profile, this is the bit built for that job.

What matters here is not just the profile size, but how this cutter is meant to work in the real world. The 27 mm cutter diameter and 6 mm radius are aimed at edge treatment work where consistency matters from the first panel to the last. Festool calls out that the cutter is suited for both plastic edging and solid wood, so it is a practical fit for finish work, cabinet parts, trim details, and edge cleanup where a smooth finished radius is the goal.

The design is specific to Festool's edge routing platform. Instead of being a generic router bit, the cutter uses a special hollow shaft that fits directly on the spindle. The benefit is higher run-out accuracy, which is the kind of detail that shows up in the cut. Better concentricity means a cleaner routing pattern and less chance of chatter showing up on the finished edge.

This is also a double-bladed cutter with two carbide edges. That gives you more usable cutting life than a single-edge design and helps when you are doing repeated edge routing on jobsite material or in a small shop workflow. Festool also notes a low installation height with a flush ball bearing mount design, which helps when routing inside rebates or working on stacked panels where clearance can be tight.

One useful detail is the way the radius transitions into a 5 degree run-out on the router blade. That is there to help protect the surface as the profile leaves the cut. On edge work, small geometry details like that can be the difference between a finished-looking part and one that still needs cleanup.

Compatibility is straightforward. This cutter is specified for the Festool OFK 500 and Festool OFKC 500. It is sold without bearing ball, so that is worth knowing before you order if you are replacing a worn cutter and expect every related part to be in the package.

Who should buy it? This is for woodworkers, cabinet installers, trim carpenters, and serious DIY users already working in the Festool edge router system. If you need a dedicated Festool router bit for repeatable roundover work on edging and solid wood parts, the Festool HW R6-OFK 500 Roundover Cutter makes sense. If you do not own a compatible OFK router, this is too specialized to be the right bit for your setup.
