Key Features
- Alloyed Steel Construction - built from durable alloyed steel that holds a sharp edge through extended production runs, reducing downtime between sharpenings and lowering tooling costs over time.

- Long-Lasting Performance - engineered for sustained cutting quality so operators can run more profiles between tool changes, supporting consistent output on molding and profiling tasks.
- Compatible with Universal Cutter Heads - designed to work across a variety of compatible cutter heads in the CMT insert shaper system, giving woodworkers the flexibility to switch profiles without investing in a new cutter body.
- Sold as a Pair (2 Knives) - each purchase includes 2 matched profile knives, ready to load as a balanced set for smooth, vibration-free cuts and consistent profile results.
Why This Product
- For shops running a CMT insert shaper system, the 690.073 profile knives allow fast profile changes without replacing the entire cutter head - just swap the knife pair and continue production with minimal interruption.
- The alloyed steel material is selected for sustained sharpness under repeated use, which means fewer sharpening cycles and more reliable profile consistency across large batches of molding or cabinet parts.
- With a universal cutter head compatibility built into the KSS 40x4mm platform, these knives work across a broad range of compatible machines - spindle moulders, moulders, and profile and edging machines - making them a versatile addition to a professional woodworking shop.
- Buying knives in matched pairs ensures balanced cutting forces on the cutter head, which contributes to a smoother surface finish and reduces stress on both the tooling and the machine spindle.
