Festool 578376 Roundover Bit HW R1-OFK 500 Z1 is designed for clean and precise edge profiling on small and delicate workpieces. This round-over router bit is primarily made for solid wood but also provides smooth results on plastic edge banding. Its innovative hollow-shaft, collet- design allows it to mount directly onto the trim router shaft without the need for a collet, ensuring stable, wobble- cutting. The outcome is a smooth, uniform round-over with a clean finish, achieved with minimal setup and maximum control. Model Number: 578376
