The CMT 818.142.11 Dovetail Router Bit by CMT is a precision-crafted 9/16 in. diameter dovetail bit engineered for cutting the classic trapezoidal dovetail profile used in furniture joinery, drawer construction, and box making. With a 14 deg. cutting angle and a 1/4 in. shank, this bit delivers the clean, interlocking cuts that define traditional dovetail joinery - whether you are working on hand-guided dovetail jig setups or routing on a router table with a fence. Built from HW (carbide) material with a right-hand rotation, this dovetail cutter is suited for woodworkers who demand accuracy and consistency when creating sliding dovetails, fitted drawer boxes, and decorative joinery in hardwood, softwood, and engineered sheet goods.

Key Features

• 14 deg. Dovetail Angle - produces the characteristic angled shoulder of a true dovetail joint, giving you tight-fitting, mechanically locked connections that resist pulling apart without glue alone.
• 9/16 in. Cutting Diameter - provides a dovetail profile wide enough for most drawer and box joinery applications, minimizing the number of passes needed to complete a joint.
• 3/8 in. Cutting Height - cuts through material up to 3/8 in. deep in a single pass, keeping routing controlled and reducing stress on both the bit and the workpiece.
• 1/4 in. Shank - compatible with a wide range of handheld routers and router tables equipped with a 1/4 in. collet, making this bit accessible for both hobbyist and professional setups.
• HW (Carbide) Cutting Material with 2 Teeth - carbide-tipped construction with 2 flutes stays sharp through extended use in hardwood and softwood, reducing the frequency of replacements and maintaining clean cut quality.
• Right-Hand Rotation - designed for standard router operation, ensuring safe feed direction and predictable cutting behavior on router tables and with handheld routers.
• 2 in. Total Length - compact overall length keeps the bit stable in the collet during routing, reducing vibration and improving cut precision.

Why This Product

• The 14 deg. angle is a widely used standard for dovetail jig work, making this bit directly compatible with common dovetail jig systems used for drawer box and cabinet construction.
• Carbide construction (HW material) with 2 cutting teeth means this bit stays sharper longer than high-speed steel alternatives, giving you cleaner dovetail shoulders even in dense hardwoods.
• The 1/4 in. shank makes this bit usable in compact trim routers as well as full-size router tables, giving woodworkers flexibility across different machine setups without needing an adapter.
• Running a straight bit first to rough out the channel, then finishing with this dovetail bit, reduces cutting stress and extends the life of the carbide edge - a workflow that pairs naturally with the bit's 3/8 in. cutting height and 9/16 in. profile.
