Product Description
CMT 690.119 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 when molding, profiling, and shaping wood and engineered wood materials, making them a dependable choice for cabinet makers, millwork shops, and woodworking professionals who demand consistent, repeatable profiles on spindle moulders and shapers.
Key Features
- Alloyed Steel Construction - the SP-grade alloyed steel material resists wear and maintains a sharp cutting edge longer, reducing downtime from frequent knife changes and keeping your profiling work on schedule.
- Profile 119 Shape - a specific, repeatable molding profile is precision-matched across both knives in the pair, ensuring symmetrical cuts and a consistent finish on every pass through hardwood, softwood, MDF, or chipboard.
- 40x4mm (1-37/64 in. x 5/32 in.) Knife Size - this standardized sizing fits CMT universal cutter heads and other compatible insert shaper systems, giving shops the flexibility to use these knives across multiple machines without adapters or modifications.
- Sold as a Matched Pair (2 knives) - both knives are included together, so you can balance the cutter head correctly right out of the package, maintaining safe operation and vibration-free cutting.
- Designed for Universal Cutter Heads - compatibility with the CMT insert shaper system means these knives can be swapped in and out quickly as profiles change, supporting fast production transitions on spindle moulders and moulding machines.
- Long-Lasting Performance - engineered for durability in demanding production environments, reducing the cost per linear foot of profile cut over the life of the knives.
Why This Product
- Shops running a CMT universal cutter head can expand their profile library simply by swapping knives - profile 119 adds a specific molding shape to your system without requiring a dedicated cutter head for every profile.
- The 40x4mm alloyed steel construction handles the rigors of production-volume shaping on hardwood, softwood, MDF, and chipboard, making these knives suitable for both custom woodworking and higher-volume millwork operations.
- Buying knives as a balanced, matched pair means you avoid the guesswork of pairing individual knives - both pieces are ready to install together for safe, vibration-free cutter head operation from the start.
- The insert shaper system format allows a variety of profiles to be run on the same cutter heads, so this knife pair extends the versatility of tooling you may already own rather than requiring a completely separate investment.

Frequently Asked Questions
What cutter heads are these knives compatible with?
The CMT 690.119 knives are designed for use with CMT universal cutter heads in the insert shaper system. The standardized 40x4mm (1-37/64 in. x 5/32 in.) sizing is intended to fit compatible insert shaper cutter heads that accept this knife format.
Why are these knives sold as a pair?
Profile knives for insert shaper systems must be installed in matched pairs to properly balance the cutter head. Using both knives together ensures safe, vibration-free rotation and symmetrical profiling on every pass.
What materials can these shaper knives cut?
The 690.119 profile knives are suited for shaping and molding hardwood, softwood, MDF, and chipboard. The alloyed steel (SP) construction supports long-lasting performance across these common woodworking materials.
Can I use these knives with other insert shaper systems besides CMT?
The knives are sized at 40x4mm (1-37/64 in. x 5/32 in.) and are part of the CMT universal cutter head system. Compatibility with non-CMT cutter heads depends on whether those heads accept the same 40x4mm knife format - always confirm your cutter head's specification before installing.
