CMT 818.190.11 Dovetail Bit from CMT is a precision-ground router bit engineered to cut the classic trapezoidal dovetail profile that woodworkers rely on for strong, interlocking joinery. With a 3/4 in. cutting diameter, a 7 deg. angle, and a 1/4 in. shank, this bit is purpose-built for use with the Incra routing system and is equally at home on a handheld router or a router table. Whether you are crafting drawer boxes, building decorative cabinets, or cutting sliding dovetails in solid hardwood, this 2-flute carbide bit delivers clean, consistent cuts that define quality craftsmanship.

Key Features

• 7 deg. Dovetail Angle - produces the precisely tapered trapezoidal profile required for tight-fitting, mechanical dovetail joints that resist pulling apart under load.
• 3/4 in. Cutting Diameter - offers a wide cutting sweep well suited to drawer box construction, box making, and sliding dovetail applications in solid wood and sheet goods.
• 7/8 in. Cutting Height - provides ample depth of cut to engage material fully, reducing the need for multiple repositioning passes and increasing efficiency.
• 2-Flute HW Carbide Construction - hard-wearing carbide teeth stay sharp through extended routing sessions, delivering smooth, splinter-free edges in hardwood, softwood, and engineered panels.
• 1/4 in. Shank - compatible with the widest range of routers and compact trim routers, making this bit versatile across job sites and workshops.
• Right-Hand Rotation - matches the standard rotation direction of virtually all fixed-base and plunge routers, ensuring safe, predictable bit behavior during operation.
• Incra System Compatible - designed specifically to work with Incra jig systems, giving woodworkers repeatable, accurately indexed dovetail cuts without the guesswork of freehand layout.
• 2 3/8 in. Total Length - a compact overall profile that maintains rigidity and reduces vibration, contributing to a cleaner cut and extended bit life.

Why This Product

• Engineered for compatibility with the Incra routing system, this bit is the right choice when accurate, repeatable dovetail indexing is a priority - not an afterthought.
• The 7 deg. angle and 3/4 in. diameter combine to produce a dovetail profile wide enough for structural drawer joinery yet precise enough for fine furniture work, covering a broad range of woodworking applications with a single bit.
• Running a straight bit for the first pass before switching to this dovetail bit reduces cutting stress and extends the working life of the carbide edges - a technique made practical by the bit's 1/4 in. shank compatibility with common router table setups.
• The hard-wearing HW carbide material handles solid hardwood, softwood, plywood, MDF, and similar sheet goods, making this a single versatile tool for both solid-wood and panel-based joinery projects.
