Key Features
- Alloyed steel construction - provides durability and long-lasting performance through repeated profiling and moulding operations, reducing downtime for replacements.
- 1-37/64 in. cutting height - delivers a substantial profile reach, enabling deeper and more defined moulding profiles in a single pass.
- 5/32 in. maximum thickness - the compact knife body fits precisely within compatible cutter heads, ensuring secure seating and vibration-free cutting.
- 40x4mm knife format (KSS standard) - compatible with CMT universal cutter heads and other insert shaper systems accepting this knife size, maximizing the range of machines these knives can be used with.
- Sold as a pair of 2 knives - both knives are matched and ready to install together, maintaining balanced cutting action and a consistent, smooth surface finish.
- Part of a variety of profile options - profile number 029 is one of many profiles available for the CMT insert shaper system, allowing shops to build a library of profiles for cabinet door making, frame and panel work, and edge profiling without investing in separate tooling for each application.
Why This Product
- For woodworkers who need a dedicated profile knife that fits into an existing universal cutter head, the 40x4mm KSS format means no new cutter body is required - simply swap knives to switch profiles and keep production moving.
- The alloyed steel material provides long-lasting performance, making these knives a cost-effective choice for shops running hardwood, softwood, MDF, and chipboard through their spindle moulder or moulder on a regular basis.
- Buying a matched pair ensures both knives share the same profile and grind, which is essential for balanced cutting and preventing vibration or chatter that can damage both the workpiece and the machine.
- Profile number 029 is a specific, repeatable profile within the CMT insert shaper system - ideal for shops that need to reproduce the same moulding or edge profile accurately across multiple production runs.
