Product Description
CMT 690.033 Profile Knives for Insert Shaper System are a pair of alloyed steel shaper knives sized 1-37/64 in. x 5/32 in. (40x4mm), designed for use with CMT universal cutter heads. These insert-style profile knives deliver long-lasting cutting performance across a wide range of molding and profiling operations, making them a reliable choice for woodworkers and cabinet makers who demand consistent, repeatable results from their spindle moulder or profile and edging machine setup.
Key Features
- Pair of profile knives (KSS 40x4mm): Sold as a matched pair - both knives are sized identically and designed to work together for balanced, vibration-free cutting on cutter head assemblies.
- Cutting height of 1-37/64 in.: Provides a defined profile depth suited for molding, edging, and frame work, giving you precise control over the finished profile shape.
- Maximum thickness of 5/32 in.: The 5/32 in. knife body thickness ensures a secure, stable fit within compatible 40x4mm insert shaper cutter heads, reducing chatter and improving surface finish quality.
- Made of alloyed steel: Alloyed steel construction offers durability and resistance to wear, extending service life and reducing the frequency of knife replacement during production runs.
- Variety of profile options available: Part of a broader system of profile knives for the universal cutter head - profile number 033 gives you a specific molding shape while remaining interchangeable within the same cutter head platform.
- Long-lasting performance: Engineered for consistent, extended use across hardwood, softwood, MDF, and chipboard - reducing downtime and maintaining a quality finish cut after cut.
Why This Product
- If you already work with a CMT 692 series universal cutter head or a compatible 40mm insert shaper system, these knives slot directly in - no adapters or extra hardware needed, making profile changes fast and straightforward.
- The matched pair format means both knives are ready to install together, keeping the cutter head properly balanced and helping you get back to production faster without sourcing individual knives separately.
- Alloyed steel construction holds an edge through demanding material types, so whether you are running softwood moldings or dense hardwood cabinet frames, the knives maintain profile accuracy without premature dulling.
- Profile number 033 is one of a variety of available profiles in the CMT insert shaper knife system, so as your project needs change, you can swap to a different profile in the same cutter head without investing in an entirely new tooling setup.
