Product Description
CMT 690.124 Profile Knives for Insert Shaper System are precision-crafted shaper knives designed for use with CMT universal cutter heads, giving woodworkers a reliable solution for consistent molding and profiling work. Sold as a pair, these 40x4mm alloyed steel knives deliver long-lasting cutting performance across a wide range of wood-based materials. Whether you are running production moldings, profiling cabinet door components, or shaping frame and panel parts, these insert shaper knives are engineered to maintain accurate profiles cut after cut.
Key Features
- Pair of profile knives in size 1-37/64 in. x 5/32 in. (40x4mm) - matched dimensions on both knives ensure balanced cutting and vibration-free performance in insert cutter heads.
- Made of alloyed steel - a tough, wear-resistant material choice that supports long-lasting performance and holds a sharp edge through extended use on hardwood, softwood, MDF, and chipboard.
- Designed for the CMT Insert Shaper System (692 series cutter heads) - purpose-built fit eliminates guesswork when swapping profiles, making changeovers fast and precise on the shaper or moulder.
- Part of a broad variety of profile knives for universal cutter heads - profile number 124 is one of many available profiles, so operators can expand their molding capabilities without changing cutter head systems.
- Profile-specific geometry - each knife is ground to a defined profile shape, producing a repeatable, smooth surface finish across all pieces without additional hand sanding or fitting.
Why This Product
- The 40x4mm knife format fits CMT 692 series cutter heads and other insert shaper systems that accept 40mm knives, making this a flexible addition to an existing shaper setup without requiring new tooling investment.
- Alloyed steel construction supports long-lasting performance in demanding production environments, reducing the frequency of knife changes and keeping downtime low during molding or profiling runs.
- Sold as a matched pair (2 knives), these inserts are ready to install as a balanced set, which is essential for smooth, chatter-free cuts on spindle moulders and profile machines.
- Profile number 124 is part of a wide CMT profile knife library, so woodworking shops can standardize on a single cutter head system and simply swap knives to produce different molding profiles - a practical, cost-effective approach to multi-profile work.
