CMT Dovetail Bit with Bearing - 9/16 in. Diameter, 14 deg. Angle, 1/4 in. Shank by CMT is a precision router bit engineered for cutting the trapezoidal profile that defines dovetail joinery. Whether you are routing hand-cut dovetails with a jig or running sliding dovetail joints on a router table, this 2-tooth carbide-tipped bit delivers clean, consistent results in solid hardwood, softwood, plywood, MDF, and more. The integrated bearing guide helps control the cut path, making this bit equally at home in handheld router and router table setups.

Key Features

• 14 deg. dovetail angle - produces the classic trapezoidal profile required for strong mechanical dovetail joints in furniture, drawer boxes, and cabinet construction.
• Bearing guide included - the built-in bearing allows the bit to follow a template or fence edge precisely, reducing the risk of drift and improving repeatability across multiple workpieces.
• 9/16 in. cutting diameter with 3/8 in. cutting height - sized for practical dovetail joinery tasks without over-stressing the shank, giving you a clean profile in a single controlled pass or with a preliminary straight-bit pass.
• 1/4 in. shank - fits a wide range of compact routers and standard router table collets, giving woodworkers with smaller machines full access to dovetail joinery capability.
• 2-tooth HW (hard metal carbide) construction - dual flutes provide balanced cutting forces and smooth chip evacuation, resulting in cleaner surfaces that require minimal sanding.
• Right-hand rotation - standard RH rotation is compatible with conventional router feed direction, allowing proper climb-cut and conventional-cut techniques as needed.
• 2 in. total length - compact overall length keeps the bit stable in the collet and reduces vibration, which translates to straighter, more accurate dovetail profiles.

Why This Product

• Bearing-guided precision for jig-based dovetail routing - the integrated bearing makes this bit well suited for use with dovetail jigs, allowing repeatable joint geometry without relying solely on fence positioning.
• Works on a router table with a fence for sliding dovetails - the 14 deg. angle and 3/8 in. cutting height make this bit a practical choice for routing sliding dovetail dadoes in cabinet shelving and box construction where a fence guides the cut.
• Reduces stress on the bit with a pre-pass technique - running the first pass with a straight bit before finishing with this dovetail bit lowers the cutting load, which helps extend tool life and improves surface quality.
• 1/4 in. shank broadens compatibility - fits compact trim routers as well as full-size routers equipped with a 1/4 in. collet, making this bit accessible to a wider range of workshop setups than larger-shank alternatives.
