Key Features
- Pair of KSS 40x4mm profile knives - sold as a matched set of 2, ensuring balanced cuts and consistent profile results on every pass through your cutter head.
- 1-37/64 in. cutting height - provides a substantial working profile, allowing you to shape defined molding contours in a single pass and reduce setup time.
- 5/32 in. maximum thickness - sized to fit securely within compatible 40mm insert cutter head systems, keeping the knife firmly seated for safe, vibration-free operation.
- Made from alloyed steel - delivers long-lasting performance and edge retention across high-volume shaping tasks on hardwood, softwood, MDF, and chipboard without frequent resharpening.
- Compatible with CMT universal cutter heads (692 series) and other insert shaper systems accepting 40mm knives - expands the versatility of your existing tooling investment by working across a broad range of spindle moulders and profile machines.
- Variety of profile options available within the insert shaper system - lets you build a set of interchangeable knives for different molding profiles using the same cutter head, reducing tooling costs over time.
Why This Product
- If you already own CMT 692 series cutter heads or any insert shaper system accepting 40mm knives, these profile knives let you expand your molding capabilities without purchasing new arbors or cutter bodies - just swap the knives for a different profile and you are ready to cut.
- The alloyed steel construction is designed for long-lasting performance, meaning less downtime for tool changes and lower replacement costs over the life of your cutter head system.
- Sold as a pair, both knives in the set are matched to the same profile geometry, so you get balanced, smooth cuts rather than the chatter or inconsistency that can result from mismatched inserts.
- The specific 40x4mm knife size is a widely compatible format, making these knives a practical choice for woodworkers who run spindle moulders, profile and edging machines, or moulder setups that accept this insert size.
