Product Description
CMT Profile Knives for Insert Shaper System - 1-37/64" x 5/32" (40x4mm), 2-Pack are precision-crafted shaper knives designed for use with CMT universal cutter heads, giving woodworkers the ability to cut consistent molding profiles in hardwood, softwood, MDF, and chipboard. Sold as a matched pair, these 40x4mm insert knives are made from alloyed steel and are engineered to deliver long-lasting performance across a wide range of profiling and molding applications on spindle moulders and profile machines.
Key Features
- Alloyed Steel Construction - provides durability and edge retention through demanding production runs, reducing the need for frequent knife replacement.
- 40x4mm Knife Size (1-37/64" x 5/32") - standardized dimensions that allow these profile knives to fit into CMT universal cutter head systems designed to accept this knife format, ensuring a secure, repeatable fit.
- Sold as a Matched Pair - both knives in the pair are ground to the same profile so the cutter head stays balanced during operation, contributing to a smoother cut and safer use.
- Variety of Profile Options Within the CMT Insert Shaper System - profile number 023 is one of many available knife profiles in the CMT system, letting users build a library of profiles for cabinet doors, frames, molding, and edge work without needing separate cutter heads.
- Long-Lasting Performance - engineered for extended service life, reducing downtime and tooling costs on high-volume shaping and molding tasks.
Why This Product
- The insert shaper knife system approach means you can change profiles quickly by swapping just the knives rather than replacing an entire cutter head - a cost-effective solution for shops that work across multiple molding profiles.
- Alloyed steel construction holds up under repeated use in hardwood and dense engineered materials like MDF and chipboard, making these knives a reliable choice for production environments where consistency matters.
- The standardized 40x4mm knife size is compatible with CMT universal cutter heads, so woodworkers already invested in CMT tooling can expand their profile library without purchasing new spindles or heads.
- Matching knife pairs promote balanced cutter head rotation, which translates directly to a cleaner surface finish and more predictable profile results on cabinet doors, frames, and decorative molding work.
