The CMT 800.524.11 3-Piece Small Arch Door Set is a precision-engineered router bit set designed for craftspeople who want to produce beautiful raised panel doors with a classic, diminutive bevelled profile. Engineered for fine furniture making and cabinetry, this set brings together matched cope and stick bits alongside a raised panel bit - giving woodworkers everything needed to craft complete door frames from a single coordinated system. With a 1/2 in. shank for secure chuck engagement and carbide-tipped cutting edges, the set delivers consistent results across a range of solid wood and panel materials.

Key Features

• 3-piece coordinated set - includes the Small Standard Raised Panel Bit and Small Standard Rail and Stile Bits in one package, eliminating the need to source matched bits separately and ensuring a perfect profile fit every time.
• Classic, diminutive bevelled profile - produces a refined raised panel door aesthetic suited to fine furniture making, heirloom cabinetry, and architectural millwork where understated elegance matters.
• Matched cope and stick geometry - the rail and stile bits are designed as a pair, so frames align precisely and joints close cleanly without hand-fitting or gap filling.
• Frame thickness range of 15.87 mm (5/8 in.) to 19 mm (3/4 in.) - accommodates the stock thicknesses most commonly used in door frame construction, making the set versatile for both furniture-grade and cabinet-grade projects.
• 1/2 in. shank - provides greater rigidity and reduced vibration compared to smaller shanks, resulting in smoother cuts and better surface finish on finished door components.
• HW (carbide-tipped) cutting material - hard carbide tips maintain a sharp edge longer than high-speed steel, reducing the frequency of sharpening and extending the working life of the set.
• Right-hand rotation - compatible with all standard handheld routers, router tables, and CNC routing machines that use conventional clockwise spindle rotation.
• CMT Orange Shield non-stick coating - prevents the bit from overheating during extended runs, reduces pitch and resin buildup on the carbide, protects against corrosion, and extends overall tool life between cleanings.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing prevents material failure at the cutting edge and extends cutting life, especially important in demanding production or repetitive use environments.
• Tri-Metal Brazing - Silver-Copper-Silver brazing bonds the carbide tips securely, protecting the joint when cutting harder wood or composites and reducing the risk of tip separation.
• Anti-kickback design - controls depth of cut and minimizes the risk of dangerous tool grab, making the set safer to use in both freehand and table-mounted router applications.

Why This Product

• For woodworkers who want matched, coordinated profiles without buying bits piecemeal, this 3-piece set delivers a complete door-making solution - raised panel bit and cope-and-stick rail and stile bits - all designed to work together from the first pass.
• The small arch door set is purpose-built for fine furniture making, where tight tolerances and a refined bevelled profile matter - making it the right choice when cabinetry quality and visual detail are priorities.
• The defined frame thickness range of 5/8 in. to 3/4 in. means the set is precisely calibrated for standard furniture-grade door stock, reducing setup time and guesswork on the router table.
• Carbide-tipped cutting edges combined with CMT Orange Shield coating and SinterHIP processing mean the set stays sharper longer and runs cleaner - reducing downtime for bit changes or cleaning during production work.
