Key Features

- Cutting height of 1-31/32 in. - allows full-depth profile passes on standard moulding stock, minimizing the number of passes required to achieve a finished profile.
- Radius range of 5mm - 6mm - produces smooth, consistent curved profiles suited to edge profiling, cabinet door detailing, and decorative frame work.
- Part of a variety of profile knives for universal cutter heads - profile number 542 integrates into a broader system of interchangeable knives, so operators can switch profiles quickly without investing in entirely new tooling.
Why This Product

- The alloyed steel material is built for long-lasting performance, meaning fewer tool changes over time and more consistent results across large production runs on hardwood, softwood, MDF, and chipboard.
- Sold as a matched pair, these knives are ready to mount and run immediately - no hunting for a matching second knife or worrying about imbalance in the cutter head.
