The CMT 800.525.11 3-Piece Divided Light Door Set is a purpose-built router bit set engineered for craftsmen who want to create authentic divided light doors for fine furniture, cabinetry, and millwork projects. This 3-piece set combines a rabbeting bit with ovolo rail and stile bits, giving woodworkers everything needed in a single coordinated package to produce clean, precisely fitted divided light door profiles. With a 1/2 in. shank for maximum stability and reduced vibration, this set is equally at home in a handheld router, router table, or CNC routing machine. Carbide-tipped cutting edges, CMT Orange Shield non-stick coating, and SinterHIP industrial chrome carbide construction make this a professional-grade tool that delivers consistent results across solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic.

Key Features

• 3-Piece Coordinated Set - includes a Rabbeting Bit (835.850.11) and Ovolo Rail and Stile Bits (855.802.11), so all profiles are matched and work together without guesswork or mismatched cutters.
• 1/2 in. Shank - the larger shank diameter provides superior rigidity and reduces vibration during cuts, resulting in smoother profiles and less tearout on fine furniture and cabinet work.
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating, reduces pitch and resin buildup, protects against corrosion, and extends tool life - keeping your bits cleaner and sharper for longer between maintenance sessions.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing (HIP) prevents material failure and extends cutting life, so you get more passes from each blade before needing replacement.
• Tri-Metal Brazing - Silver-Copper-Silver brazing protects the carbide tip when cutting harder wood or composites and reduces the chance of failed welds, giving you confidence when working through dense or abrasive materials.
• Anti-Kickback Design - controls depth of cut and minimizes kickback risk, improving operator safety and making this set more approachable for woodworkers at any skill level.
• Right-Hand Rotation - compatible with standard router spindle direction, meaning no special setup or adapters are needed for most routers and router tables.
• 2-Tooth Cutting Configuration - optimized for clean chip evacuation and smooth surface finish across a wide range of compatible materials including solid hardwood, softwood, MDF, laminates, and melamine.
• Carbide-Tipped (TCT) Blades - tungsten carbide tipping holds an edge far longer than high-speed steel, reducing downtime and resharpening frequency during high-volume door production.

Why This Product

• Building divided light doors requires precise, coordinated profiles across the rabbet, rail, and stile - this 3-piece set delivers all three matched cutters in one package, eliminating the risk of profile mismatches when sourcing bits separately.
• The 1/2 in. shank combined with SinterHIP carbide construction means this set handles demanding materials like solid hardwood and composites without deflection or premature wear, making it a reliable choice for production cabinet and furniture shops.
• CMT Orange Shield coating and Tri-Metal Brazing address two of the most common causes of router bit failure - heat buildup and weld separation - helping this set stay in service longer with less maintenance.
• The anti-kickback design and right-hand rotation make this set compatible with standard routers, router tables, and CNC machines, so woodworkers can integrate it into existing workflows without additional equipment or setup.
