Both helical and spiral cutterheads use durable carbide inserts with four cutting edges, enabling quieter operation and cost-effective maintenance by rotating or replacing individual inserts. Helical cutterheads have inserts mounted at a slight angle, creating a shearing action for smoother finishes, while spiral cutterheads have inserts perpendicular to the workpiece, offering slightly less smooth results. Both provide long-lasting performance and quieter operation compared to traditional HSS knives.
Both helical and spiral cutterheads use carbide inserts instead of traditional high-speed steel (HSS) knives, offering quieter operation and easier maintenance. Each insert has four cutting edges, so you can rotate or replace only the damaged inserts rather than replacing full blades, saving time and money.
Helical Cutterheads
- Inserts are mounted at a slight angle to the direction of the cut.
- This creates a shearing action, which many customers find produces smoother results.
- Preferred by most customers for its finish quality.
Spiral Cutterheads
- Inserts are mounted perpendicular to the workpiece travel.
- Performance difference is subtle, but generally less smooth than helical.
- Still offers the same benefits of carbide inserts and quieter operation.
Key Benefits of Both Styles
- Quieter than traditional HSS knives.
- Cost-effective maintenance: Rotate or replace individual inserts instead of full blades.
- Durable carbide inserts for long-lasting performance.
