Product Description
CMT Insert Carbide Straight Router Bit - 1/2 in. Diameter, 1/2 in. Shank by CMT is a single-edge, replaceable-knife routing tool engineered for fast plunge cuts, dado routing, grooving, and mortising in laminated stock, softwood, and hardwood. With a 1 in. 3/16 in. cutting height and right-hand rotation, this insert straight bit is purpose-built for use in CNC routers and portable hand routers alike, delivering consistent, clean cuts in demanding production and woodworking environments.
Key Features
- Insert Carbide Knife Design - The single replaceable carbide knife (Z1) can be swapped when worn rather than discarding the entire bit, reducing long-term tooling costs for production shops and frequent users.
- 1 in. 3/16 in. Cutting Height - Generous cutting depth in a single pass means fewer setups for dadoes, grooves, and mortises in thick stock, improving workflow efficiency.
- 1/2 in. Shank Diameter - A full 1/2 in. shank provides maximum rigidity and minimal vibration during aggressive material removal, resulting in cleaner cuts and reduced operator fatigue.
- Right-Hand Rotation - Standard RH rotation is compatible with the vast majority of hand routers and CNC spindles, making this bit a versatile drop-in solution for most setups.
- HW Carbide Material - Hard metal (HW) carbide construction maintains a sharp cutting edge longer than standard high-speed steel, keeping performance consistent across softwood, hardwood, and laminated panels.
- CNC and Portable Router Compatible - Engineered to perform in both CNC and hand-router applications, giving woodworkers and production operators the flexibility to use one tool across multiple machine types.
Why This Product
- The replaceable insert knife design means you replace only the carbide cutter - not the entire bit body - making this an economical choice for shops running high-volume grooving or dado work in hardwood and laminated panels.
- A 1 in. 3/16 in. cutting height combined with a rigid 1/2 in. shank makes this bit well-suited for deep plunge cuts and through-groove operations that demand both depth capacity and stability.
- Compatibility with both CNC routers and portable hand routers means this single bit transitions seamlessly between production environments and job-site applications, reducing the need for duplicate tooling.
- HW carbide construction holds a working edge through demanding materials including laminated stock, softwood, and hardwood, reducing the frequency of stops for tool changes during extended cutting sessions.

Frequently Asked Questions
How many cutting edges does this insert straight bit have?
This bit features a single insert knife (Z1 - one tooth). The carbide insert knife is replaceable, so when the cutting edge dulls, you can swap in a fresh knife rather than replacing the entire bit body.
What is the maximum cutting depth this bit can achieve in a single pass?
The cutting height (depth of cut) for the CMT 651.727.11 is 1 3/16 in., making it suitable for deep dadoes, grooves, and mortises without requiring multiple repositioned passes.
Is this bit compatible with CNC routers or only hand routers?
This insert straight bit is designed for use in both CNC routers and portable hand routers. The 1/2 in. shank and right-hand rotation are standard configurations compatible with most CNC spindles and hand-router collets of the appropriate size.
What materials can this router bit cut effectively?
The HW (hard metal carbide) insert knife is suited for cutting laminated stock, softwood, and hardwood. These material categories cover a wide range of common woodworking panel and solid-wood applications.
