Protech | Router Ogee Panel Raiser 3 1/2" X 3/4" 1/2" Shank
The raised panel is captured in a groove made in the inside edge of the frame members. Panels are made slightly smaller than the available space within the frame to provide room for movement. Wood will expand and contract across the grain, and a wide panel made of solid wood could change width by up to 6mm, warping the door frame.
By allowing the wood panel to float, it can expand and contract without damaging the door. A typical panel would be cut to allow 5mm between itself and the bottom of the groove in the frame.
A raised panel has a profile cut into its edge so that the panel surface is flush with or proud of the frame. Some popular profiles are the ogee, chamfer, and scoop or cove.
This router bit is for machining of traditional panels & frame doors with heavy duty routers mounted in fixed positions, either inverted or overhead. These Raised Panel cutters perform best at lower speeds. They are all suitable for use on natural timbers and MDF (medium density fibre board).
