Key Features
- Alloyed Steel Construction - made of alloyed steel for durability and edge retention through extended production runs, reducing the frequency of blade changes and downtime.
- Precision Profile Design (40x4mm) - the 1-37/64 in. cutting height and 5/32 in. maximum thickness ensure the profile is reproduced accurately and consistently on every pass, giving you clean, tight-fitting joints and molding details.
- Compatible with Universal Cutter Heads - fits CMT universal cutter heads in the insert shaper system, so you can swap profiles quickly without changing the entire head, making multi-profile projects faster and more economical.
- Sold as a Matched Pair - both knives in each pack are ground to the same profile standard, ensuring balanced cutting action that reduces vibration and produces a smoother surface finish.
- Long-Lasting Performance - built for repeated use in demanding woodworking environments, these knives help maximize productivity and reduce per-piece tooling costs over time.
Why This Product
- The 40x4mm knife size works within the CMT universal cutter head system, letting you build a library of profile knives for the same head - a cost-effective approach for shops that run multiple molding profiles regularly.
- Alloyed steel construction means the cutting edges hold up through demanding production work on both solid wood species and engineered sheet goods like MDF and chipboard, reducing interruptions for sharpening or replacement.
- Precision-ground matched pairs deliver balanced cutting forces, which translates to less vibration at the spindle, a smoother surface right off the machine, and less time spent on sanding or hand-finishing.
- Profile number 052 gives you a clearly catalogued knife choice within the CMT insert shaper system, making it straightforward to reorder or expand your profile knife collection as your work demands grow.
