- 40x4mm Knife Size (1-37/64 in. x 5/32 in.) - precise dimensions ensure a secure, consistent fit in compatible universal cutter heads, reducing setup time and repeat adjustments.
- Sold as a Matched Pair - both knives in the set are ground to the same profile, so you get balanced cutting performance and a smooth, even surface finish right out of the box.
- Compatible with the CMT Universal Cutter Head System - designed for use with CMT insert shaper cutter heads (692 series), giving woodworkers access to a wide variety of interchangeable profile knives within a single system.
- Profile 041 Geometry - a specific molding profile engineered for repeatable results in molding, profiling, and decorative edge work on wood-based materials.
Why This Product
- Expand your profile library without buying new heads - because these knives fit the CMT universal cutter head system, you can swap profiles quickly and cost-effectively, getting more from your existing shaper tooling investment.
- Built for sustained use - the alloyed steel material is engineered for long-lasting performance, meaning fewer interruptions to replace worn tooling during high-volume molding or profiling work.
- Precision-matched pair for balanced cuts - both knives in the 2-piece set share the same ground profile, which helps maintain a consistent, clean finish on hardwood, softwood, MDF, and chipboard without tearout or uneven profiles.
- Standardized 40x4mm sizing - the 40x4mm form factor is a widely used insert knife standard, making these knives a practical choice for shops running spindle moulders, moulders, or profile and edging machines that accept this knife size.
