Key Features
- Alloyed Steel Construction - provides durability and long-lasting performance, reducing the frequency of knife replacement during demanding production runs.
- 40x4mm Knife Size (1-37/64 in. x 5/32 in.) - fits precisely into compatible universal cutter heads, ensuring a secure seating and accurate profile reproduction on every pass.
- Profile Knife Pair (2 knives per set) - both knives are matched and ground to the same profile, so you get balanced cutting action and a smooth, uniform surface finish.
- Designed for Universal Cutter Heads - compatible with a variety of insert shaper systems, giving woodworkers the flexibility to use one set of cutter heads across multiple knife profiles without dedicated tooling.
- Part of the CMT Insert Shaper System - allows you to swap profiles quickly and expand your molding capabilities simply by changing knife sets rather than entire cutter assemblies.
Why This Product
- Built from alloyed steel for extended service life - these profile knives hold their edge longer, meaning fewer changeovers and more consistent results across high-volume molding and profiling work.
- The 40x4mm form factor fits a variety of universal cutter heads, making this pair a practical choice for shops that already run insert shaper systems and want to expand their profile library without investing in new heads.
- Sold as a matched pair of 2 knives, so you always have both cutting members ready - no need to source individual knives or worry about mismatched profiles between cutting edges.
- As part of the CMT Insert Shaper System, these knives integrate into a broader ecosystem of cutter heads and profiles, allowing woodworkers to handle cabinet door making, frame and panel work, and edge profiling with a single system.
