Product Description
CMT 690.544 Profile Knives for Insert Shaper System are a pair of precision-engineered shaper knives sized 1-31/32 in. x 5/32 in. (50x4mm), designed to work with CMT universal cutter heads for consistent molding and profiling results. Made from alloyed steel, these knives deliver long-lasting performance across a wide range of woodworking applications including cabinet door making, edge profiling, and frame and panel work. Whether you are running hardwood, softwood, MDF, or chipboard, these insert shaper knives are built to produce smooth, repeatable profiles on spindle moulders and profile machines alike.
Key Features
- Alloyed steel construction - provides durability and long-lasting edge retention, reducing the frequency of knife changes during production runs.
- 1-31/32 in. cutting height (50mm) - accommodates a substantial profile depth, giving woodworkers flexibility for decorative molding and edge profiling tasks.
- 5/32 in. (4mm) maximum thickness - ensures a precise, controlled cut geometry suited to fine profile work on cabinet doors, frames, and panels.
- 30mm radius profile - delivers a defined, consistent curve that is ideal for classical molding profiles and decorative edging on solid wood and sheet goods.
- Part of the CMT Insert Shaper System variety - pairs with CMT universal cutter heads so you can swap profiles quickly without changing the entire tooling setup, saving setup time and cost.
- Sold as a pair (2 knives) - both knives are matched and ready to install together, ensuring balanced cutting and a uniform finished profile from the first pass.
Why This Product
- Designed for the CMT Insert Shaper System - if you already run CMT 692 series cutter heads or compatible universal cutter heads, these knives slot directly in with no additional adapters needed, making tooling changes fast and straightforward.
- Profile 544 for specific molding work - the 30mm radius geometry of profile 544 is purpose-built for applications like cabinet door edge profiling and frame molding where a clean, consistent curve is critical to the finished look.
- Alloyed steel for sustained performance - the steel alloy material supports repeated use across hardwood, softwood, MDF, and chipboard without rapid dulling, making these knives a practical choice for both production shops and serious hobbyists.
- Matched pair included - receiving two matched knives in one pack means you can mount balanced tooling immediately, which is important for safe, vibration-free operation at spindle speeds.
