CMT 818.130.11 Dovetail Bit by CMT is a precision-ground routing bit engineered to cut the classic trapezoidal dovetail profile, making it ideal for dovetail joinery in woodworking projects ranging from drawer construction to decorative box making. With a 1/2 in. cutting diameter and a 14 deg. angle, this bit produces the characteristic interlocking shape that gives dovetail joints their legendary mechanical strength and visual appeal. Designed specifically for compatibility with the Incra system, it brings accuracy and repeatability to both professional cabinet shops and dedicated hobbyist workshops. The 1/4 in. shank fits a wide range of handheld routers and router tables, making this a versatile tool for routing solid hardwood, softwood, and engineered sheet goods alike.

Key Features

• 14 deg. Dovetail Angle - produces the precise trapezoidal profile required for tight-fitting dovetail joints and sliding dovetail connections, ensuring strong mechanical interlock without relying on fasteners or adhesive alone.
• 1/2 in. Cutting Diameter - delivers a full-width dovetail cut in a single pass, reducing the number of setups needed and speeding up production on drawer boxes and cabinet carcasses.
• 1/2 in. Cutting Height - accommodates typical drawer side and box wall thicknesses, giving you a deep, structurally sound dovetail slot in one routing operation.
• HW (Hard Metal/Carbide) Cutting Material - provides superior edge retention over high-speed steel, allowing cleaner cuts across more lineal feet before resharpening is needed, whether you are working in solid hardwood or plywood.
• 2-Flute (2-Tooth) Configuration - balances cutting speed and surface quality, producing a smooth dovetail wall that minimizes tearout and reduces the sanding or fitting work needed after routing.
• Right-Hand (RH) Rotation - matches the standard rotation direction of virtually all handheld routers and router table spindles, ensuring safe, predictable cutting behavior.
• 1/4 in. Shank - compatible with the vast majority of compact and full-size routers, giving this bit broad machine versatility for job site and shop use.
• Incra System Compatibility - engineered to work with Incra jigs and fences for repeatable, precision-indexed dovetail routing, reducing setup time and eliminating costly trial-and-error fitting on joints.
• 2-7/16 in. Total Length - provides adequate clearance above the workpiece and collet, allowing the bit to seat fully in the collet while still projecting the full cutting height needed for dovetail work.

Why This Product

• The 14 deg. angle is a widely used standard dovetail geometry that works with popular dovetail jigs and the Incra system, making this bit a natural fit if you already own or plan to use an Incra-compatible setup for repeatable joinery.
• The carbide (HW) cutting material maintains a sharp edge longer than conventional steel bits, which translates directly to cleaner dovetail walls and consistent joint fit across a full production run of drawer boxes or keepsake boxes.
• With a 1/4 in. shank and right-hand rotation, this bit slots into compact trim routers as well as full-size table-mounted routers without adapters, giving you the flexibility to choose your preferred machine for the task.
• The 2-flute design strikes a practical balance between cutting speed and finish quality, making this bit well suited for both the occasional craftsperson cutting a handful of joints and the production woodworker routing multiple assemblies in a session.
