CMT Dovetail Bit - 1/2 in. Diameter, 8 deg. Angle, 1/4 in. Shank is a precision-ground carbide-tipped router bit engineered for creating clean, accurate dovetail joints in wood and woodworking composites. Designed for compatibility with the Incra system, this right-hand rotation bit delivers the classic trapezoidal dovetail profile that woodworkers rely on for strong, interlocking joinery in drawer boxes, cabinets, and decorative box construction. With a 2-tooth configuration and hardmetal (HW) carbide cutting edges, it handles everything from solid hardwood to softwood with consistent, repeatable results.

Key Features

• 8 deg. Dovetail Angle - produces a shallower, precise dovetail profile ideal for Incra system jig work, delivering tight-fitting joints with minimal tearout
• 1/2 in. Cutting Diameter - wide enough to form a full dovetail profile in a single pass, reducing the number of passes needed and speeding up production
• 13/16 in. Cutting Height - provides sufficient depth of cut to accommodate standard drawer sides and box stock thicknesses in one setup
• 2-Flute HW Carbide Construction - hardmetal carbide teeth stay sharp through extended use in solid hardwood and softwood, meaning less downtime for bit changes
• 1/4 in. Shank - compatible with a wide range of compact routers, trim routers, and router tables fitted with a 1/4 in. collet, expanding versatility across your tool collection
• Right-Hand Rotation (RH) - standard rotation matches all conventional router collets, so no special setup or tooling adapters are required
• Incra System Compatible - designed to work with Incra jig systems, enabling precise, repeatable dovetail layouts for professional-quality joinery
• 2-3/4 in. Total Length - compact overall length keeps the bit stable at operating speeds and reduces vibration for cleaner cuts

Why This Product

• The 8 deg. angle is specifically calibrated for Incra system users who need exact, consistent dovetail geometry - this bit eliminates guesswork and produces repeatable joints straight out of the box.
• Hardmetal (HW) carbide cutting edges hold their edge through demanding cuts in solid hardwood, meaning professional woodworkers get extended working sessions without sacrificing joint quality.
• The 1/4 in. shank opens this bit to trim routers and compact router setups, making high-quality dovetail joinery accessible without requiring a full-size router.
• With a 13/16 in. cutting height and 1/2 in. diameter, this bit is proportioned for real-world drawer and box joinery - not undersized for show, but matched to the stock thicknesses woodworkers actually use.
