Freud 99-571 3-1/2-Inch Raised Panel Router Bit w/Backcutters (Quadra-Cut)

These Raised Panel Bits include a backcutter that routs a rabbet on the back of the door panel, resulting in a 3/4″-thick panel that sits flush with the doorframe for a professional, architecturally correct appearance. Shims are included to allow adjustment of tongue thickness from 7/32″ to 1/4″ for maximum versatility and compatibility. Exclusive Quadra-Cut design includes two cutters that shear upwards and two edges shearing downward to deliver a flawless finish. Use in table-mounted routers with fence only. Suitable for hardwood, softwood or composite panels.
