The Festool ¼" Roundover Bit HW R6‑OFK 500 is built for controlled, accurate edge rounding on solid wood and plastic edge banding. Designed for use with Festool trim routers, this bit delivers a smooth, consistent round‑over on small parts and detailed work where precision matters and margins are tight.

A hollow, direct‑thread design mounts straight to the router shaft without a collet, reducing run‑out and improving stability at the cut. That direct connection helps maintain uniform contact through the entire pass, producing clean profiles with less vibration and better surface quality. Dual carbide cutting edges extend cutting life while maintaining consistent results across repeat passes.

Its low‑profile geometry allows access in tight areas such as rabbets or stacked panels, making it easier to maintain control when space is limited. A precision‑ground radius blends into a 5° relief angle, easing the exit cut to reduce surface marking and cleanup time. The result is a refined edge that holds its shape and finish.
