Key Features
- Alloyed Steel Construction - the SP-grade alloyed steel material provides long-lasting performance and holds a sharp edge through extended production runs, reducing downtime for knife changes.
- KSS 40x4mm Format - the standardized 40mm x 4mm knife size ensures compatibility with CMT universal cutter heads and other insert shaper systems that accept this profile knife format, giving you flexible tooling options.
- 1-37/64 in. Cutting Height - the generous cutting height allows for full, expressive molding profiles in a single pass, improving efficiency and surface consistency on profiling and edging work.
- 5/32 in. Maximum Thickness - the precise knife thickness is matched to the insert shaper cutter head slot tolerances, ensuring secure seating and vibration-free cutting performance.
- Sold as a Matched Pair - two knives are included in every pack, so both cutter head positions are filled with identically profiled blades for balanced cutting and a smooth, tear-out-free finish.
- Part of the CMT Universal Insert Shaper System - these profile knives are designed to work within a broader system of interchangeable profiles, letting you build a versatile library of molding shapes around a single set of cutter heads.
