Key Features
- Pair of profile knives in the KSS 40x4mm format - sold as a set of 2 so you have a matched pair ready to install for balanced, consistent cutting performance.
- Made of alloyed steel - delivers long-lasting performance and holds a sharp edge through extended production runs on hardwood, softwood, and engineered panels.
- Designed for CMT universal cutter heads - part of a broad variety of profile knives for the insert shaper system, giving woodworkers the flexibility to switch profiles without changing cutter heads.
- Cutting height of 1-37/64" with a maximum thickness of 5/32" (40x4mm) - precise dimensions ensure a secure, stable fit within compatible insert shaper cutter heads for accurate, repeatable profiles.
- Long-lasting performance - alloyed steel construction maintains cutting geometry over time, reducing downtime for resharpening or replacement during heavy-use operations.
Why This Product
- If you already own a CMT universal cutter head system, these 40x4mm profile knives let you expand your molding capabilities simply by swapping knives - no need to invest in additional cutter bodies for each new profile.
- The alloyed steel construction provides durability suited to production environments where knives are used repeatedly across hardwood, softwood, MDF, and chipboard workpieces.
- Profile number 079 is part of a wide variety of available CMT insert shaper profiles, so woodworkers building a library of profiles can mix and match knives to cover common molding, edging, and cabinet door applications.
- Precision dimensions of 1-37/64" x 5/32" mean each knife seats correctly in the cutter head, reducing the risk of vibration or uneven cuts that can result from poorly fitting shaper knives.
