Product Description
The CMT 818.722.11 Dovetail Bit is a precision-engineered routing tool designed for cutting the classic trapezoidal dovetail profile used in fine woodworking joinery. With a 7 deg. angle and a 7/8 in. cutting diameter, this 2-flute carbide-tipped bit delivers clean, accurate cuts for hand-routed dovetails, sliding dovetail joints, and drawer construction alike. Built for use with the Incra system and compatible with both handheld routers and router table setups, it gives woodworkers - from seasoned professionals to enthusiastic beginners - the control and reliability needed to produce tight-fitting, beautiful dovetail joints in solid hardwood, softwood, plywood, MDF, and more.
Key Features
- 7 deg. dovetail angle with 7/8 in. cutting diameter - produces the precise trapezoidal profile required for snug, interlocking dovetail joinery without the need for hand-fitting or excessive adjustment.
- HW (carbide) cutting material - hard-wearing tungsten carbide edges maintain sharpness through extended routing sessions, reducing the need for frequent tool changes and keeping cuts smooth and consistent.
- 2-flute (2-tooth) design with right-hand rotation - dual cutting edges improve chip clearance and surface finish quality, resulting in cleaner joint faces directly off the router.
- 1/2 in. shank diameter - the larger shank provides greater stability and reduced vibration during cutting, which translates to more accurate results and less chatter on the workpiece.
- Incra system compatibility - designed to work precisely with Incra jig setups, making it easier to produce repeatable, perfectly matched dovetail joints across multiple workpieces.
- 7/8 in. cutting height - sufficient depth of cut for typical drawer sides and box joinery applications, allowing full through-cuts in common stock thicknesses in a controlled pass.
- 2-3/4 in. total length - compact overall length keeps the bit stable and balanced in the collet, minimizing deflection during routing for straighter, more accurate joints.
Why This Product
- The 7 deg. dovetail angle is a standard choice for furniture-grade drawer joinery and box construction, making this bit a practical go-to for woodworkers who need reliable, repeatable results on common hardwood and softwood projects.
- Designed specifically for compatibility with the Incra system, this bit pairs seamlessly with one of the most precise dovetail jig platforms available, taking the guesswork out of setup and alignment.
- The 1/2 in. shank size - the larger of the two common router shank standards - provides a more rigid connection in the collet, reducing vibration and improving cut quality compared to 1/4 in. shank equivalents, especially on harder materials.
- For best results and reduced stress on the bit, the first pass can be made with a straight bit before the dovetail bit cleans up the profile - a technique that extends tool life and produces smoother joint walls.

Frequently Asked Questions
Is this dovetail bit compatible with the Incra dovetail jig system?
Yes. The CMT 818.722.11 is specifically designed for use with the Incra system, making it well-suited for achieving precise, repeatable dovetail joints when used with that jig platform.
What is the recommended technique for getting the cleanest dovetail cuts with this bit?
For easier routing and less stress on the bit, run a first pass with a straight bit to remove the bulk of the material, then follow with the dovetail bit to cut the final profile. Always check that dovetails have been cut through completely and smoothly before removing the workpiece from the jig.
Can this bit be used on a router table as well as a handheld router?
Yes. The 1/2 in. shank and 2-3/4 in. total length make it suitable for use in both handheld router and router table configurations. When used on a router table equipped with a fence, it can also be used to achieve difficult chamfer angles.
What does the 7 deg. angle mean for joint fit, and how does it compare to steeper dovetail angles?
The 7 deg. angle is a relatively shallow dovetail profile, which is commonly used in furniture and drawer construction where a strong mechanical lock is needed without excessive undercutting. It is well-suited for hardwoods and softwoods alike and pairs well with standard dovetail jig setups like the Incra system.
