Sold as a pair in the 50x4mm size (1-31/32 in. cutting height x 5/32 in. maximum thickness), these profile knives are built to deliver long-lasting performance across a wide range of molding and profiling applications on wood-based materials. Whether you are running a spindle moulder, a moulder, or a profile and edging machine, the CMT 690.508 set integrates directly into the CMT insert shaper system for repeatable, accurate results.
Key Features
- Alloyed steel construction - provides durability and resistance to wear over extended production runs, reducing the frequency of knife replacement.
- 1-31/32 in. cutting height - delivers a deep, full profile cut in a single pass, minimizing the need for multiple setups or repeated passes.
- 5/32 in. maximum thickness - the slim knife profile fits precisely into compatible insert cutter heads, maintaining accurate alignment for consistent molding results.
- Designed for CMT universal cutter heads - integrates with the CMT insert shaper system so you can swap profiles quickly without replacing the entire cutter head assembly.
- Sold as a pair (2 knives) - both knives are matched and ready to install as a balanced set, helping maintain smooth, vibration-free operation in the cutter head.
Why This Product
- The 50x4mm knife size fits the CMT universal cutter head system, giving woodworkers and production shops the flexibility to run a variety of profiles using a single cutter head body - this reduces tooling investment and changeover time on the shop floor.
- Alloyed steel construction is selected for long-lasting performance, making this knife pair a practical choice for both intermittent cabinet shop use and higher-volume production environments where consistent edge quality matters across many linear feet of material.
