Sold as a pair in the 50x4mm (1-31/32 in. x 5/32 in.) size, these insert shaper knives deliver long-lasting performance across a wide range of molding and profiling tasks. Whether you are running a spindle moulder, moulder, or profile and edging machine, the 690.503 knife set integrates cleanly into the CMT insert shaper system to produce consistent, repeatable profiles.
Key Features
- Pair of KSS 50x4mm profile knives - sold as a matched set of 2, so both knives are replaced together for balanced cutting and uniform profile results.
- Made of alloyed steel - provides the toughness and edge retention needed to sustain long-lasting performance through repeated production runs.
- Part of the CMT universal cutter head system - compatible across a variety of CMT cutter heads, giving woodworkers the flexibility to switch profiles without investing in entirely new tooling.
- Profile number 503 knife geometry - a specific molding profile that ensures consistent output when used with compatible insert shaper cutter heads.
- 50x4mm knife size (1-31/32 in. x 5/32 in.) - standardized dimensions that fit within the insert shaper system without modification, reducing setup time at the machine.
Why This Product
- The alloyed steel construction and the design of these knives for the CMT universal cutter head system means woodworkers can swap profiles quickly without changing the entire cutter head - reducing downtime and tooling cost per profile.
- Buying the 690.503 as a pair ensures both cutting edges are matched in profile and condition from the start, helping maintain a balanced cut and a smoother finished surface on hardwood, softwood, and engineered panel materials.
