Key Features
- Alloyed Steel Construction - made of alloyed steel for durability and extended cutting life, reducing the need for frequent knife replacement during demanding shaper operations.
- 40x4mm (1-37/64 in. x 5/32 in.) Knife Size - precise dimensions ensure a consistent, repeatable profile on every pass, supporting clean results in molding and edge profiling applications.
- Compatible with Universal Cutter Heads - fits a variety of CMT universal cutter heads in the insert shaper system, giving woodworkers the flexibility to swap profiles without investing in entirely new tooling.
- Sold as a Pair (2 Knives) - both knives are included together so the cutter head is always balanced and ready for use right out of the package, saving time and ensuring safe operation.
- Long-Lasting Performance - engineered for sustained use on hardwood, softwood, MDF, and chipboard, minimizing downtime and maintaining profile quality over repeated production runs.
Why This Product
- The 40x4mm knife format is a widely accepted size for insert shaper systems, making this pair a practical fit for woodworkers already working with CMT universal cutter heads who need a specific profile without retooling their entire setup.
- Alloyed steel construction supports long-lasting cutting performance across a range of wood-based materials including hardwood, softwood, MDF, and chipboard - reducing tool change frequency on production runs.
- Knives are sold in pairs, meaning both sides of the cutter head are matched from the start, which helps maintain a balanced cut and consistent profile depth without additional sourcing or guesswork.
- As part of the CMT insert shaper system, these profile knives are interchangeable with a variety of profiles across the same cutter head platform - a cost-effective approach to expanding profiling capabilities on a spindle moulder or moulder.
