The CMT 890.524.11 Raised Panel Bit with Back Cutter is a professional-grade router bit engineered for routing the beveled, decorative edge profile on cabinet door panels and frame-and-panel assemblies. Featuring Profile A and a generous 3 1/2 in. cutting diameter, this carbide-tipped bit is designed for use on router tables and CNC routing machines where consistent, clean raised panel profiles are required. What sets this bit apart from standard raised panel bits is its integrated back cutter, which allows the router bit to mill both the front face and the back edge of the panel in a single pass - eliminating the need for a separate back-cutting operation and saving setup time. Compatible with solid hardwood, softwood, MDF, plywood, and composite panel materials, this right-hand rotation bit handles stock up to 13/16 in. thick.

Key Features

• Raised Panel Bit with Integrated Back Cutter (Profile A) - mills both the front and back of the panel in the same cut, eliminating a separate machining step and reducing total setup and production time on cabinet door panels.
• 3 1/2 in. Cutting Diameter - delivers a full, sweeping raised panel profile with a 15/16 in. radius, producing the bold, traditional look associated with high-quality frame-and-panel cabinet doors.
• HW (Carbide) Cutting Material - hardmetal carbide cutting edges maintain sharpness through extended runs on hardwood, softwood, MDF, plywood, and composite materials, reducing the frequency of bit changes.
• 1/2 in. Shank - the larger 1/2 in. shank provides superior rigidity and reduced vibration compared to smaller shanks, resulting in smoother cuts and improved surface finish on raised panel profiles.
• 2-Tooth Configuration - a balanced 2-flute design offers smooth chip evacuation and an even cut load during raised panel routing, supporting consistent results across the full panel edge.
• Right-Hand Rotation - designed for standard right-hand rotation routers and router tables, ensuring compatibility with the vast majority of professional routing setups.
• Maximum Material Thickness of 3/4 in. to 13/16 in. - accommodates the standard panel stock thicknesses used in traditional and contemporary cabinet door construction.
• Total Length of 3 5/64 in. - provides sufficient clearance for proper mounting in a 1/2 in. collet router table setup while maintaining stable bit engagement during cutting.

Why This Product

• Single-pass front and back profiling - the built-in back cutter allows both faces of the panel to be profiled in one setup, which is a meaningful time saver compared to raised panel bits that require a second pass or a separate back-cutter bit.
• Purpose-built for standard cabinet panel stock - the 3/4 in. to 13/16 in. maximum thickness capacity aligns directly with the most common solid wood and plywood panel thicknesses used in frame-and-panel door construction, making this a practical choice for cabinetmakers and woodworkers.
• Profile A compatibility with rail and stile sets - Profile A is one of the most widely used raised panel profiles, designed to pair with matching Profile A rail and stile router bit sets for complete door construction workflows.
• Large 3 1/2 in. diameter for bold panel definition - the generous cutting diameter produces a pronounced, deep raised panel profile with a 15/16 in. radius, giving cabinet doors strong visual character suitable for traditional and transitional cabinetry styles.
