The CMT 818.690.11 Dovetail Bit is a precision-crafted routing bit designed to cut the classic trapezoidal dovetail profile used in furniture making, drawer construction, and fine woodworking joinery. With a 7 deg. angle, a 3/4 in. cutting diameter, and a 1/2 in. shank, this bit is engineered for use with the Incra jig system and delivers the smooth, tight-fitting dovetail joints that both professional woodworkers and dedicated hobbyists expect from CMT tooling. Whether you are running it on a router table with a fence or guiding it through a dovetail jig, this right-hand rotation bit handles solid hardwood, softwood, and sheet goods with consistent, repeatable results.

Key Features

• 7 deg. dovetail angle - produces a precisely angled trapezoidal cut that locks mating pieces together for strong, gap-free dovetail joints in furniture and cabinetry applications.
• 3/4 in. cutting diameter with 7/8 in. cutting height - provides generous material removal per pass, reducing the number of passes needed and increasing efficiency on drawer sides, box joints, and sliding dovetail channels.
• 1/2 in. shank - fits most full-size routers and router table setups, providing a secure grip that reduces vibration and deflection during the cut for cleaner, more accurate results.
• 2-flute (2-tooth) carbide construction (HW material) - hardmetal carbide cutting edges stay sharp longer than high-speed steel alternatives, meaning more cuts per sharpening cycle and lower long-term cost per joint.
• Right-hand rotation - standard RH rotation is compatible with virtually all handheld routers and router tables, eliminating compatibility concerns when setting up your workstation.
• Compatible with the Incra jig system - designed to work with Incra's precision positioning jigs so you can dial in perfectly repeatable dovetail spacing without layout marking or trial-and-error adjustments.
• 2-5/8 in. total length - provides enough reach for typical dovetail jig setups while keeping the bit compact enough to maintain rigidity and minimize runout at the cutting edge.

Why This Product

• Specified for the Incra jig system - if you already own or plan to use Incra's precision dovetail jigs, this bit is designed to pair directly with that system, removing guesswork from angle and spacing setup.
• The 7 deg. angle is well-suited for sliding dovetail joints in furniture components such as shelving, carcass construction, and drawer dividers, where a shallower angle provides easier assembly while still locking the joint mechanically.
• Running a straight bit for a first roughing pass before using this dovetail bit - as recommended in the product guidance - reduces cutting load, extends the life of the carbide edges, and produces a cleaner finished profile on the dovetail walls.
• The 1/2 in. shank paired with a 3/4 in. diameter cutting head gives a balanced ratio of shank strength to cutting width, making this bit a practical choice for router table use with a fence to cut chamfer angles and guided dovetail profiles in a single controlled operation.
