Key Features
- Matched Pair - KSS 40x4mm Format: Sold as a pair of 2 profile knives in the KSS 40x4mm size - ensures balanced cutting on both sides of the cutter head for smooth, vibration-free profiling passes.
- Alloyed Steel Construction: Made of alloyed steel - provides durability and resistance to wear during repeated use on hardwood, softwood, MDF, and chipboard workpieces.
- Long-Lasting Performance: Engineered for extended service life - reduces the frequency of knife changes and downtime on the shop floor, keeping production running efficiently.
- Universal Cutter Head Compatibility: Designed for use with CMT universal cutter heads - gives woodworkers access to a wide variety of profile shapes within a single, versatile insert shaper system.
- 1-37/64 in. Cutting Height: The 1-37/64 in. cutting height accommodates substantial profile depth - suitable for decorative molding, door frame, and edge-profiling applications that require a full, well-defined profile.
- 5/32 in. Maximum Thickness: The 5/32 in. knife body thickness (4mm) fits the standard KSS slot in compatible cutter heads - ensuring a secure, repeatable seating for consistent profile accuracy from run to run.
Why This Product
- Woodworkers who already own CMT universal cutter heads can expand their profiling capability simply by swapping knife pairs - no need to invest in additional cutter bodies for each new profile.
- The alloyed steel material provides a balance of hardness and toughness that supports long-lasting cutting performance across demanding materials including hardwood and MDF.
- The KSS 40x4mm format is widely compatible with CMT insert shaper cutter heads, making these knives a practical addition to any shop already equipped with the CMT 692 series or compatible universal cutter systems.
- Buying profile knives in a matched pair (2 knives) means both sides of the cutter head are replaced simultaneously - maintaining balanced cutting geometry and a consistent, clean surface finish on every pass.
