Spiral cutterhead: The spiral cutterhead features a row of sharp carbide blades arranged in a spiral pattern around a central cylinder. This design ensures smoother and more stable cutting compared to traditional straight-knife blades, making it ideal for softwoods. The durable tungsten carbide blades require almost no maintenance. The spiral cutterhead also utilizes a cylindrical core but with carbide blades arranged in a spiral. They deliver a higher-quality surface finish with reduced noise and vibration. When the blades become worn, the multi-edged blades can be rotated to a new cutting edge, reducing costs.
Spiral Cutterhead vs. Straight-Knife Cutterhead: Feature Comparison
| Feature | Spiral Cutterhead | Straight-Knife Cutterhead |
|---|---|---|
| 1. Design | Square carbide blades arranged in a spiral pattern | Similar to spiral cutterhead, but blades are arranged in straight rows |
| 2. Cutting Action | Shearing action, smooth surface, less wood tear-out | Efficient, but not as smooth as spiral cutterhead |
| 3. Best for Wood Types | Hardwoods, complex grain woods | Softwoods, most hardwoods |
| 4. Durability | High (rotatable blades extend lifespan) | High, but may require more frequent replacement |
| 5. Maintenance | Low (blades can be easily rotated) | Relatively low, simple replacement process |
| 6. Noise Level | Lower (due to shearing action) | Slightly higher |
| 6. Cost | Higher initial cost, cost-effective in the long run | More affordable, good performance-to-cost ratio |
Each spiral cutter insert has four sharp edges, carbide tipped. Carbide tipped blades stay sharp for much longer than ‘normal’ HSS blades. And when they get dull, you can simply rotate them a quarter turn, and use the next sharp side. So you get longer lasting blades and they can be used four times. This leads to a way longer blade life overall.
An additional benefit is that if you damage a blade, for example by hitting a nail in the wood, you only have to remove one cutter instead of the entire blade. This is a significant cost saving.
