Key Features
- Alloyed steel construction - provides durable, long-lasting cutting performance through repeated use on wood and engineered wood materials.
- 1-31/32 in. cutting height with 5/32 in. maximum thickness (50x4mm) - precise knife dimensions ensure accurate profile depth and clean, consistent shaping results.
- Designed for CMT universal cutter heads - fits the insert shaper system for versatile profile interchangeability without changing the entire cutter head.
- Sold as a pair - both knives included so the cutter head is fully loaded and balanced right out of the package.
Why This Product
- The insert shaper system approach means you can swap profile knives to run a different molding shape without replacing the entire cutter head - saving time and tooling cost when switching between profiles on a spindle moulder or similar machine.
- The alloyed steel material is engineered for long-lasting performance, meaning fewer changeovers and more consistent profile quality across high-volume woodworking and cabinet shop applications.
