The Festool HW R5-OFK 500 roundover cutter is a carbide-tipped router bit made for rounding over edges on plastic and solid wood. This is a roundover cutter designed for edge profiling and finishing. Model Number 490095. If you are using a Festool edge router and want a clean, repeatable profile without fussing with setup, this is the cutter built for that job.

What matters here is not just the 5 mm radius, but how this bit is meant to work in real use. The 27 mm diameter and matched radius give you a defined profile for softening exposed edges, finishing trim details, and cleaning up solid wood parts so they feel finished instead of sharp. That makes it a practical choice for cabinet parts, edge banding cleanup, and general woodworking where the edge quality is what people notice first.

The Festool HW R5-OFK 500 roundover cutter uses a special hollow shaft design that fits directly on the spindle. In plain terms, that direct fit helps improve run-out accuracy, which means the cutter spins truer and leaves a cleaner routing pattern. That is the kind of detail that matters when you are working visible edges, because small vibration or wobble shows up quickly in the final finish.

Festool also gives this cutter a two-edge carbide cutting design. Two carbide cutters means longer usable life and more dependable performance over repeated edge-routing work. If you are doing production-style edge work or just do not want to swap cutters as often, that is a real benefit. Carbide also makes sense here because this bit is intended for both plastic and solid wood edging, where edge wear can show up fast on lower-grade cutters.

Another practical detail is the low installation height created by the flush ball bearing mount. According to Festool, that helps when routing in rebates or on stacked panels, where clearance matters. There is also a 5 degree run-out transition on the router blade to help protect the surface at the edge. That is the kind of design feature you appreciate when you are trying to leave a finished-looking edge with less cleanup afterward.

Compatibility is straightforward: this cutter is made for the Festool OFK 500 and Festool OFKC 500. It is not a general-purpose router bit being pitched as universal. It is a purpose-built edge-routing accessory for those specific Festool routers, which is exactly why it should appeal to users already working in that platform and looking for the right profile cutter instead of a compromise.

This cutter makes the most sense for finish carpenters, cabinet installers, millwork shops, and serious DIY woodworkers who are already using a Festool edge router for edge treatment. If your work includes rounding plastic edging, easing sharp corners on solid wood, or putting a consistent finished edge on visible parts, this accessory is the right kind of specialized tool. If you do not own an OFK 500 or OFKC 500, this is not the bit to buy. If you do, it is the exact kind of application-specific cutter that makes those routers more useful.
