Best Thickness Planer With Helical Cutterheads for Precise Woodworking
For woodworkers seeking cleaner finishes, quieter operation, and more durable cutting edges, a thickness planer with a helical cutterhead can be a game changer. Helical heads use multiple carbide inserts arranged in a spiral, delivering smoother cuts, reduced tear-out, and longer blade life compared to traditional straight knives. This guide highlights five strong options, examining how their cutterheads, speeds, and build quality translate to real-world results. Whether you’re resurfacing hardwoods or planning softwood stock, these units offer consistent thicknessing and better surface quality. The summary table below helps you compare key specs at a glance.

| WEN PL1337 | WEN Store | Spiral, 26 HSS blades | 6 in thick x 13 in wide | Two-speed operation |
| FindBuyTool 13″ | FIND BUY TOOL Store | Helical cutter head with 40 tungsten carbide inserts | 13 in width | High accuracy, anti-wobble design |
| DEWALT DW735X | DEWALT Store | Three-knife traditional head (not helically configured here, noted for comparison) | 13 in width | Two-speed, 15 A |
| DeWalt 13″ Helical Head Kit | Unbranded/Replacement | Helical, 56 carbide inserts | Fits DW735/DW735X | Noise reduction and longer life |
To help you decide, this article evaluates five popular options that emphasize helical cutterheads, with attention to thickness capacity, feed speed, precision, and maintenance needs. The products range from benchtop units designed for hobbyist shops to upgrade kits that fit existing DeWalt machines, ensuring a spectrum of compatibility for various woodworking goals.
WEN PL1326 15-Amp 13-Inch Spiral Benchtop Thickness Planer
The WEN PL1326 uses a spiral cutterhead with 26 staggered and rotatable HSS blades, delivering a clean, smooth finish on a variety of woods. An onboard material removal gauge helps operators track cutting depth per pass, supporting consistent results. This planer handles boards up to 6 inches thick and 13 inches wide, making it suitable for small-to-medium projects and workshop setups seeking reliable performance with straightforward maintenance.
WEN Thickness Planer, Two Speed, 13-Inch Spiral Blade, Benchtop (PL1337)
This model adds a two-speed feed option, enabling a faster 26 FPM for quick dimensioning and a slower 16 FPM for finer finish work. The spiral cutterhead with 26 staggered HSS blades continues to deliver smooth cuts, while maintaining the same 6-inch-by-13-inch capacity. The dual-speed feature makes it versatile for projects needing both efficiency and precision without switching machines.
FindBuyTool 13″ Benchtop Wood Thickness Planer With Helical Cutterhead
FindBuyTool’s benchtop planer emphasizes a helical cutter head with 40 tungsten carbide inserts, designed to deliver the best-cut results. The unit focuses on accuracy and stability, featuring a four-column anti-wobble foundation to achieve thickness tolerance better than 0.1 mm. This configuration makes it a solid option for precision-focused projects and for users upgrading a standard planer to a helical head system.
DEWALT Thickness Planer, 13-inch Wood Planer, Three Knife Two Speed
DEWALT’s 13-inch planer combines a robust 15-amp motor with a three-knife cutter head offering 30% longer knife life and faster knife changes. The two-speed gearbox enables adjustments to the feed rate for different materials and cut quality, delivering a balance of power and efficiency for frequent, broader cuts on a benchtop. While not a helical head by default, it remains a central reference point for comparing traditional knife life and performance against modern helical systems.
13 Inch Spiral Helical Cutterhead for DeWalt DW735/DW735X Planer
This replacement cutterhead kit is designed to fit DeWalt DW735, DW735X, and DW735-XE planers. It features a 13-inch spiral head with 4 cutting wings and 56 carbide inserts, delivering a high-quality, smooth finish with extended blade life. Carbide inserts offer superior wear resistance, and the design promises a noticeable reduction in noise compared to traditional straight-knife configurations. It’s an ideal upgrade for shops using DW735-series machines seeking quieter operation and longer maintenance intervals.
Buying Guide
Key considerations when selecting a thickness planer with a helical cutterhead include cutterhead design, material compatibility, and overall system rigidity. Helical heads with more inserts typically deliver smoother cuts and less tear-out, especially on difficult woods, but may involve higher replacement insert costs. Look for:
– Insert quantity and material: Carbide inserts last longer and resist wear that can affect finish quality.
– Depth capacity and width: Ensure the machine handles the stock sizes you most often work with.
– Feed speed and consistency: Two-speed systems provide a balance between fast material removal and finish quality.
– Stability features: Four-column or anti-wobble bases improve thickness tolerance and reduce snipe.
– Noise and dust management: Spiral heads generally reduce noise and produce finer chips, aiding dust collection.
– Compatibility and upgrade options: Some brands offer heads as direct replacements or compatible upgrades for existing machines, expanding your long-term options.
– Maintenance and blade change: Spiral cutterheads typically require inserting/replacing small carbide segments rather than full blade changes, which can save downtime during maintenance.
For different user profiles:
– Hobbyists: A compact benchtop with a reliable spiral head, good depth gauge, and straightforward maintenance is ideal for occasional projects.
– Professional shops: A heavier, higher-capacity planer with quick-change inserts, solid castings, and vibration damping will sustain production workloads.
– Upgraders: Replacement spiral head kits for popular models can extend the life of an older machine, offering improved finish without a full equipment purchase.
In summary, a thickness planer with a helical cutterhead is well-suited to achieving smoother finishes, improved cut quality, and longer blade life. Matching cutterhead design with your typical material and project size will yield the best long-term results, while considering upgrade paths can protect your investment as your workflow evolves.
