Product Description
CMT 690.555 Profile Knives for Insert Shaper System are a matched pair of alloyed steel shaper knives sized 1-31/32 in. x 5/32 in. (50x4mm), designed for use with CMT universal cutter heads in the CMT Insert Shaper System. These knives deliver long-lasting performance in molding, profiling, and edge shaping applications on wood and wood-composite materials. Sold as a pair of 2 knives, they are engineered to consistent dimensional tolerances so woodworkers and millwork professionals can achieve repeatable, clean profile results across production runs.
Key Features
- Alloyed steel construction - provides the toughness and edge retention needed for sustained performance in demanding shaping and molding applications, reducing downtime from frequent knife changes.
- 1-31/32 in. x 5/32 in. (50x4mm) knife size - fits CMT universal cutter heads designed for 50mm profile knife inserts, giving you a secure, precisely fitted cutting system.
- Sold as a matched pair - both knives in the set share the same profile geometry, so the cutter head stays balanced and delivers a consistent, smooth surface finish on every pass.
- Part of a broad variety of profile knives for universal cutter heads - CMT offers multiple profile numbers in this same knife format, making it straightforward to expand your molding capabilities without investing in new tooling systems.
Why This Product
- For woodworkers already using CMT universal cutter heads, these 50x4mm profile knives slot directly into an existing investment in CMT Insert Shaper System tooling - no new heads or adapters required, just swap the knife profile and get back to production.
- The alloyed steel material and matched-pair design work together to maintain cutting accuracy over extended use, making these knives a practical choice for shops that need reliable profile consistency across large runs of molding, cabinet frames, or edging work.
