CMT 818.674.11 Dovetail Bit by CMT is an 11/16 in. diameter, 8 deg. angle router bit engineered to cut the classic trapezoidal dovetail profile that woodworkers depend on for strong, interlocking joinery. With a 1/2 in. shank and a 1 in. cutting height, this two-flute, right-hand rotation bit is designed for use with the Incra system and handles everything from traditional drawer construction and box making to sliding dovetail joints in solid hardwood and sheet goods. Whether you are routing at the router table with a fence or making freehand passes with a handheld router, this carbide-tipped bit delivers the precision geometry that makes dovetail joinery both functional and visually striking.

Key Features

• 11/16 in. Diameter at 8 deg. Angle - produces a precisely proportioned dovetail profile that fits accurately into matching sockets, reducing the need for hand-fitting and cleanup.
• 1/2 in. Shank - provides a rigid, vibration-resistant connection to the router collet, improving cut accuracy and surface finish in both handheld and table-mounted routing setups.
• 1 in. Cutting Height - gives you full engagement depth in a single routing pass through typical drawer sides and box stock, minimizing the number of repositioning steps required.
• 3-1/16 in. Total Length - allows comfortable reach when working at the router table, keeping the shank fully seated in the collet even when routing deeper profiles.
• 2-Flute HW Carbide Construction - hardwood-grade carbide edges stay sharp through extended production runs in solid hardwoods, softwoods, and composite sheet materials.
• Right-Hand (RH) Rotation - matches the standard rotation direction of virtually all handheld routers and router tables, so the bit installs and runs without any special setup.
• Incra System Compatible - optimized geometry integrates directly with the Incra jig system, making repeatable, precise dovetail layout straightforward for both hobbyists and professional woodworkers.

Why This Product

• The 8 deg. angle geometry is specifically sized for Incra system compatibility, meaning you get consistent, repeatable dovetail joints without trial-and-error setup adjustments every time you change stock.
• Running a straight bit for the first pass before switching to this dovetail bit reduces load on the carbide edges, extending cutting life and producing a cleaner finished profile - an approach well suited to production woodworking and high-volume cabinet or drawer work.
• The 1/2 in. shank and two-flute carbide construction together minimize chatter during the cut, which is especially important when routing the angled walls of a dovetail socket where tearout and fuzz directly affect joint fit.
• At 3-1/16 in. total length with a 1 in. cutting height, the bit is proportioned for practical router table use with a fence, letting you dial in chamfer angles and joint depth without the bit bottoming out or losing shank engagement.
