Why This Product

- Alloyed steel construction provides the edge durability needed for repeat profiling runs on hardwood, softwood, MDF, and chipboard, reducing the frequency of knife changes during production work.
- Buying profile knives as a matched pair means your cutter head stays balanced from the moment you load the tool, which directly translates to smoother profiles and cleaner surface finishes on your workpieces.
