Product Description
CMT 690.099 Profile Knives for Insert Shaper System are a pair of alloyed steel shaper knives sized 1-37/64 in. x 5/32 in. (40x4mm), designed for use with CMT universal cutter heads in the insert shaper system. These KSS-format profile knives deliver long-lasting molding performance on a wide range of wood materials, making them a reliable choice for woodworkers and millwork professionals who demand consistent profile results from their spindle moulders and profiling machines.
Key Features
- Alloyed Steel Construction - the SP-grade alloyed steel material provides strength and durability, so the knives maintain their edge through extended production runs and repeated sharpenings.
- 40x4mm (1-37/64 in. x 5/32 in.) Knife Size - the precise KSS 40x4mm format fits the CMT universal cutter head system, ensuring a secure, wobble-free seating that produces accurate, repeatable profiles in every pass.
- Sold as a Matched Pair - both knives in the pair are ground to the same profile, so the cutter head stays balanced and vibration is minimized during operation, resulting in a smoother surface finish on workpieces.
- Universal Cutter Head Compatibility - designed for the CMT insert shaper system, these knives work with a variety of universal cutter heads, reducing the need to invest in dedicated tooling for each profile.
- Long-Lasting Performance - consistent performance over time means less downtime for tool changes and lower overall tooling costs for high-volume or recurring profiling tasks.
Why This Product
- The 40x4mm KSS format is a widely accepted standard in insert shaper systems, so these profile knives integrate into existing CMT universal cutter head setups without requiring additional adapters or modifications.
- Alloyed steel construction gives these shaper knives the toughness needed to handle hardwood, softwood, and sheet goods consistently - making them a practical choice for cabinet door making, frame and panel work, and edge profiling.
- Purchasing a matched pair ensures both knives share an identical profile, which is essential for balanced cutter head loading and achieving clean, professional-quality molding results on every workpiece.
- Profile number 099 is part of a broader variety of CMT insert shaper profile knives, allowing woodworkers to build a versatile library of profiles using a single cutter head platform - a cost-effective approach to profiling and moulding operations.
