Product Description
CMT 690.030 Profile Knives for Insert Shaper System are a matched pair of alloyed steel shaper knives sized 1-37/64 in. x 5/32 in. (40x4mm), designed for use with CMT universal cutter heads in the insert shaper system. These profile knives deliver long-lasting performance across a wide range of molding, profiling, and edge-shaping applications, making them a reliable choice for woodworkers who demand consistent results on hardwood, softwood, MDF, and chipboard.
Key Features
- Alloyed steel construction - provides durability and resistance to wear, extending the service life of each knife and reducing downtime for replacements during production runs.
- Profile number 030 geometry - delivers a specific molding profile engineered to produce repeatable, accurate results on cabinet doors, frames, and decorative edge work.
- 1-37/64 in. cutting height x 5/32 in. maximum thickness (40x4mm) - precisely sized for compatibility with universal cutter heads in the CMT insert shaper system, ensuring a secure, accurate fit.
- Sold as a matched pair of 2 knives - both knives in the set are ground to the same profile, so the cutter head remains balanced and produces a uniform finish on every pass.
- Compatible with a variety of profile knife styles for universal cutter heads - allows woodworkers to build out a versatile shaping system by swapping profiles as needed without replacing the cutter head itself.
Why This Product
- Purpose-built for the CMT insert shaper system - the 40x4mm knife size fits directly into compatible universal cutter heads, eliminating guesswork and setup frustration when configuring a spindle moulder or profile and edging machine.
- Long-lasting alloyed steel means fewer change-outs - the material selection supports extended production cycles, making these knives a practical choice for shops running hardwood, softwood, MDF, or chipboard on a regular basis.
- Matched pair design supports balanced cutting - running a balanced pair of profile knives reduces vibration at the cutter head, which translates directly to smoother surface finishes and more consistent profile depth across the workpiece.
- Flexible profile system expands capability - because these knives are part of a broader range of profile options for universal cutter heads, choosing profile 030 gives woodworkers a specific molding shape while retaining the flexibility to add other profiles to the same cutter head system over time.

Frequently Asked Questions
What cutter heads are these profile knives compatible with?
These 40x4mm profile knives are designed for use with CMT universal cutter heads in the insert shaper system. The 1-37/64 in. x 5/32 in. knife size is the correct fit for that system's cutter head lineup, allowing profile 030 to be installed securely for molding and shaping work.
What materials can profile 030 knives cut?
The alloyed steel construction of these knives supports long-lasting performance on hardwood, softwood, MDF, and chipboard - covering the range of materials commonly used in cabinet making, frame and panel work, and decorative molding applications.
How many knives come in the package?
The CMT 690.030 is sold as a matched pair of 2 knives. Running both knives together in the cutter head keeps the assembly balanced and ensures a consistent, uniform profile on every pass through the workpiece.
Can these knives be used on different profile shapes if I need another profile?
Each set of CMT insert shaper knives is ground to a specific profile - in this case, profile number 030. To cut a different profile shape, you would select the corresponding profile knife number from the available range of knives for universal cutter heads. The cutter head itself remains the same, so building out a range of profiles is straightforward within the insert shaper system.
