The CMT 818.111.11 Dovetail Bit delivers the precise 8 deg. angle and 7/16 in. cutting diameter needed to produce the classic trapezoidal dovetail profile prized in fine woodworking and cabinetry. Engineered with a 1/4 in. shank and hardened carbide (HW) cutters, this right-hand rotation bit is purpose-built for dovetail joinery work, including sliding dovetails, drawer box construction, and decorative box making. Fully compatible with the Incra system, it gives both professional woodworkers and dedicated hobbyists the repeatability and fit required for tight, gap-free dovetail joints in solid hardwood, softwood, plywood, and sheet goods alike.

Key Features

• 8 deg. dovetail angle - produces the specific tapered undercut geometry that locks mating dovetail joints together mechanically, reducing reliance on glue alone and creating stronger drawer and box assemblies.
• 7/16 in. cutting diameter - a compact profile sized for tight-pitch dovetail patterns, giving you more joint placements per board width and finer detail in narrow stock.
• 5/8 in. cutting height - provides enough depth of cut to handle typical drawer side and box wall thicknesses in a single pass, keeping workflow efficient.
• Hardened carbide (HW) cutting material - resists wear on hardwoods and abrasive sheet materials, maintaining a sharp edge longer so joints stay precise across extended production runs.
• 2-flute design - balanced cutting geometry delivers smoother chip evacuation and a cleaner finished surface, reducing sanding and fitting time after routing.
• 1/4 in. shank - fits a wide range of routers and router tables, making this bit accessible for compact trimmers and full-size routers alike.
• Right-hand (RH) rotation - matches the standard rotation of all conventional handheld routers and router tables for safe, predictable feed direction.
• Incra system compatible - designed to work seamlessly with the Incra joinery system for repeatable, indexed dovetail cuts without layout guesswork.
• 2-3/8 in. total length - provides sufficient clearance above the collet when used in a router table setup, reducing the risk of collet contact with the workpiece.

Why This Product

• The 8 deg. taper angle is a woodworking-standard geometry specifically suited to hand-routed dovetail jig work and Incra system setups, making this bit the right match for those workflows rather than a general-purpose compromise.
• The compact 7/16 in. diameter paired with a 5/8 in. cutting height is sized for the drawer and box joinery applications where tight dovetail spacing matters most - a combination that lets you cut more joints in less material width.
• Hardened carbide (HW) construction means the bit holds its edge through repeated passes on dense hardwoods and composite sheet materials, so joinery remains consistent from the first joint to the last.
• The 1/4 in. shank makes this bit compatible with a broad range of compact and full-size routers, lowering the barrier to entry for woodworkers who do not own a larger 1/2 in. shank collet router.
