Product Description
CMT 690.097 Profile Knives for Insert Shaper System - 1-37/64" x 5/32" (40x4mm), 2-Pack by CMT are precision-engineered shaper knives designed for use with universal cutter heads in woodworking shaping and profiling operations. Sold as a matched pair, these alloyed steel knives deliver long-lasting performance across a wide range of molding and profiling tasks - making them a reliable choice for cabinetmakers, furniture builders, and woodworking professionals who depend on consistent, repeatable results from their spindle moulder or profile machine.
Key Features
- Alloyed steel construction - provides strength and durability throughout extended use, reducing the frequency of knife replacement and keeping production moving.
- Profile number 097 knife geometry - delivers a specific, repeatable molding profile so every pass produces a consistent shape with minimal sanding or cleanup.
- 1-37/64" cutting height x 5/32" maximum thickness (40x4mm) - precise dimensions ensure a secure, accurate fit in compatible 40mm insert shaper cutter heads, eliminating play or vibration during cuts.
- Universal insert shaper system compatibility - works with a variety of cutter heads designed for the KSS 40x4mm knife format, giving woodworkers flexibility across different machine setups.
- Sold as a matched pair (2 knives) - both knives are ground and matched together, so balanced cutting is maintained and setup time is kept to a minimum.
- Long-lasting performance - designed for sustained use on hardwood, softwood, MDF, and chipboard without premature dulling, supporting high-volume or production-level workflows.
Why This Product
- For woodworkers who run a spindle moulder or profile machine and need a dependable, matched knife set, these alloyed steel profile knives provide the consistency and edge retention required for production work on a variety of wood and composite materials.
- The 40x4mm knife format is widely compatible with universal insert shaper cutter heads, meaning these knives integrate into existing tooling setups without requiring a dedicated or proprietary cutter body.
- Purchasing a matched pair in a single package simplifies inventory management and ensures both knives are balanced and ground to the same profile - critical for vibration-free cuts and smooth surface finish on moldings and shaped edges.
- Profile number 097 addresses specific molding and edge profiling applications such as cabinet door making and frame and panel work, allowing woodworkers to achieve detailed profile shapes with a single tooling investment rather than custom-ground knives.
