Product Description
CMT 818.628.11 Dovetail Bit by CMT is a precision-ground router bit engineered to cut the classic trapezoidal dovetail profile at a 14 deg. angle - ideal for creating tight, interlocking dovetail joints in solid hardwood, softwood, and wood-based sheet goods. With a 1/2 in. shank and 1/2 in. cutting diameter, this two-flute right-hand rotation bit is compatible with the Incra system and delivers the clean, smooth cuts that both professional woodworkers and dedicated hobbyists demand for drawer construction, box making, and sliding dovetail applications.
Key Features
- 14 deg. Dovetail Angle - produces the precise trapezoidal profile required for strong mechanical dovetail joints, ensuring a tight fit between mating pieces without relying solely on glue.
- 1/2 in. Cutting Diameter with 1/2 in. Cutting Height - delivers a dovetail slot sized for dependable joinery in standard stock thicknesses, reducing the need for multiple passes.
- 1/2 in. Shank - provides a secure, low-vibration connection in 1/2 in. router collets, improving cut accuracy and reducing chatter during routing.
- 2-Flute (2-Tooth) Configuration with Right-Hand Rotation - two cutting edges work together to produce smooth, clean dovetail profiles with each pass, minimizing tearout on the workpiece.
- HW (Carbide) Cutting Material - hard carbide construction maintains a sharp cutting edge longer than standard steel, reducing the frequency of bit replacement and keeping cuts consistent over time.
- 2 1/2 in. Total Length - compact overall length keeps the bit stable and well-supported in the router collet, contributing to precise, repeatable results.
- Compatible with the Incra System - designed to work with Incra jig setups, enabling accurate, repeatable dovetail layouts for production work or multi-piece projects.
- Pre-Pass Strategy Supported - using a straight bit for the first pass before finishing with this dovetail bit reduces stress on the cutting edges and extends the usable life of the bit.
Why This Product
- The 14 deg. angle is specifically suited for the Incra system, making this bit a direct fit for woodworkers who already rely on that jig for precise, repeatable dovetail layouts - no guesswork or adapter needed.
- The carbide (HW) cutting material holds an edge through repeated passes in hardwood and softwood alike, meaning fewer interruptions to resharpen or replace the bit during a project.
- At 1/2 in. diameter and 1/2 in. cutting height, this bit is matched to common dovetail joint dimensions used in drawer boxes and cabinet construction, reducing setup time and trial cuts.
- Right-hand rotation and a two-flute design make this bit equally at home in a handheld router with a dovetail jig or mounted in a router table with a fence - covering the two most common routing setups for dovetail work.

Frequently Asked Questions
What angle does this dovetail bit cut?
This bit cuts at a 14 deg. angle, producing the trapezoidal profile characteristic of classic dovetail joinery. This specific angle is designed to work with the Incra system for accurate, repeatable results.
Can this bit be used on a router table as well as a handheld router?
Yes. This dovetail bit is compatible with both handheld routers using dovetail jigs and router tables equipped with a fence. When used on a router table with a fence, it can also achieve difficult chamfer angles.
Is there a recommended technique to extend the life of this bit?
Yes. Running the first pass with a straight bit before using the dovetail bit reduces stress on the cutting edges, making routing easier and helping preserve the carbide cutting material for a longer service life.
How do I know the dovetail has been cut correctly before removing the workpiece?
Check that the dovetail has been cut through completely and smoothly before removing the workpiece. This ensures a clean profile and reduces the risk of an incomplete joint that could affect fit and strength.
