Key Features
- Alloyed Steel Construction - made of alloyed steel for durability and resistance to wear, extending service life even under demanding production use.

- Designed for the Universal Cutter Head Insert Shaper System - compatible with a wide variety of CMT universal cutter heads, giving woodworkers flexibility to swap profiles without changing the entire tooling setup.
- Sold as a Pair of 2 Knives - knives must be installed in matched pairs for proper balance and safe cutter head operation, and this pack includes both knives needed for a complete setup.
- Long-Lasting Performance - engineered for extended cutting cycles, reducing downtime and the frequency of knife changes in production environments.
Why This Product
- The 40x4mm knife format fits the CMT insert shaper system, meaning you can expand your profile library simply by swapping knives rather than investing in entirely new cutter heads - a practical and cost-effective approach for shops running multiple profiles.
- Alloyed steel construction means these knives hold their edge through repeated use on hardwood, softwood, MDF, and chipboard, reducing the need for frequent replacement in high-volume production settings.
- Knives arrive as a matched pair, so you have everything required for a balanced, safe installation right out of the box - no need to source individual knives separately.
- The universal cutter head compatibility makes these knives a versatile addition to any shop running spindle moulders or profile and edging machines, covering applications from cabinet door making to decorative molding and frame and panel work.
