The CMT 890.527.11 Raised Panel Bit with Back Cutter - Profile B is a professional-grade router bit engineered to produce beautifully beveled, profiled edges on cabinet door panels and frame-and-panel assemblies. Built by CMT, this 3 1/2 in. diameter bit features a back cutter that mills both the front and back face of the panel in a single pass, saving time and delivering a cleaner, more consistent result across solid hardwood, softwood, plywood, MDF, and composite materials. Designed for use on router tables, handheld routers, and CNC routing machines, it is an ideal tool for cabinetmakers and woodworkers who need reliable, repeatable raised panel profiles with maximum efficiency.

Key Features

• Back Cutter Design - mills both the front and back face of the panel in the same cut, eliminating the need for a second pass and reducing overall machining time on cabinet door panels.
• Profile B Shape - delivers a specific raised panel profile suited to traditional and transitional cabinet door styles, giving woodworkers a consistent, repeatable decorative edge without secondary shaping.
• 3 1/2 in. Cutting Diameter - the large diameter provides a broad, sweeping profile that covers the full raised panel bevel in one setup, reducing repositioning and improving workflow.
• 1 1/2 in. Radius - produces a smooth, flowing arc on the panel face that translates into elegant, finished cabinet door aesthetics right off the bit.
• HW (Carbide-Tipped) Cutting Material - hard carbide tips stay sharp longer when cutting solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic, reducing downtime for resharpening.
• 2-Tooth Configuration - balanced 2-flute geometry provides smooth chip evacuation and reduced vibration for a cleaner surface finish on raised panel edges.
• 1/2 in. Shank - the heavy-duty 1/2 in. shank offers maximum rigidity and minimizes deflection under the load of this large-diameter bit, improving cut accuracy and operator safety.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of routers and router table setups, making this bit straightforward to install and use without any special configuration.
• Material Thickness Range of 3/4 in. to 1 in. - accommodates the most common cabinet panel stock thicknesses so woodworkers can work with standard lumber and sheet goods without custom adjustments.
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating, reduces pitch and resin buildup on the carbide, protects against corrosion, and extends overall tool life for a lower cost per cut.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing prevents material failure at the cutting edge and extends cutting life, meaning fewer replacements and more consistent results over time.
• Tri-Metal Brazing - Silver-Copper-Silver brazing protects the carbide tip when cutting harder wood or composites, reducing the risk of weld failure and keeping the cutting edge securely bonded under heavy use.
• Anti-Kickback Design - controls the depth of cut to limit the potential for sudden, dangerous bit grabs, making the bit safer to operate on a router table or handheld router.

Why This Product

• One-pass front-and-back milling - the integrated back cutter profiles both faces of the raised panel in a single setup, which is a genuine time saver compared to standard raised panel bits that require a second operation to clean up the back face.
• Built for full-thickness cabinet stock - the 3/4 in. to 1 in. material thickness capacity directly matches the most common solid wood and plywood panel thicknesses used in cabinet door construction, removing the guesswork from bit selection.
• Handles hardwood, softwood, and composites - the HW carbide tips combined with Tri-Metal Brazing and SinterHIP processing mean this bit can move from solid oak or maple to MDF or melamine without changing tooling, reducing setup time in mixed-material shops.
• Long service life through advanced coatings and carbide processing - the Orange Shield non-stick coating, SinterHIP carbide, and Tri-Metal Brazing work together to extend the usable life of the bit and maintain cutting performance over many linear feet of raised panel routing.
