Révolutionnez votre raboteuse DeWalt DW735 de 13" d'épaisseuravec des têtes de coupe en spirale pour les avantages suivants.
* Finition de meilleure qualité sans déchirure. Tous les inserts sont inclinés le long de l'hélice de manière décalée et produisent des effets de coupe de cisaillement, même sur du bois dur très figuré.
* Le bruit est considérablement réduit car la tête de coupe en spirale maintient un contact constant avec la planche avec seulement quelques couteaux.
* Tous les couteaux sont fabriqués en carbure de tungstène solide qui est beaucoup plus dur et reste tranchant plus longtemps que les lames en acier rapide. Si un bord est ébréché ou émoussé, faites-le pivoter de 90° pour obtenir un nouveau bord tranchant. Chaque plaquette possède quatre arêtes de coupe et peut être utilisée quatre fois.
* Facile à mettre en place. Les plaquettes indexables en carbure sont rectifiées avec précision selon une tolérance très serrée et sont interchangeables. Desserrez les vis, tournez à 90° et serrez les inserts en quelques minutes. Les inserts peuvent être positionnés avec précision grâce au verrouillage de type trou conique.
* Les inserts en carbure plus petits éliminent les matériaux plus courts et plus fins, ce qui facilite grandement l'extraction de la poussière.
* À long terme, les têtes de coupe en spirale sont moins chères à utiliser et peuvent être rentabilisées en très peu de temps.
Le kit de têtes de coupe en spirale comprend :
* Bloc de coupe en acier allié à haute résistance à la traction.
* 40 plaquettes carbure à installer.
* 5 inserts en carbure supplémentaires et 5 vis supplémentaires gratuites comme pièces de rechange.
* Une paire de roulements scellés haut de gamme prémontés.
* 1 clé
Cette tête de coupe en spirale est conçue et fabriquée pour avoir le même cercle de coupe que la tête de coupe d'origine OEM. Le bloc de coupe doit être installé à travers l'alésage du roulement dans le carter de la machine, tous les couteaux sont retirés de la tête de coupe après l'équilibrage dynamique. Cela vous évite d’avoir à effectuer le retrait vous-même.
Les têtes de coupe en spirale Sheartak sont fabriquées selon les normes industrielles et sont soumises à des contrôles et des tests de haute qualité. Tous les couteaux sont fabriqués à ±0,0004"/0,01 mm pour garantir l'interchangeabilité. Les couteaux en carbure peuvent être réglés en toute sécurité dans le même cercle de coupe.
Vous pouvez couper jusqu'à 1/8" par passe maximum. Un inconvénient est que vous devrez passer environ une demi-heure à installer tous les inserts en carbure sur le bloc de coupe.
Lisez le manuel et regardez la courte vidéo avant d'installer les inserts en carbure. L'installation des inserts en carbure est facile.
I had put a Sheartak helical cutter head installed in my DeWalt 735 in Guelph (Sheartak installed it for free when I dropped the planer off at their shop in Waterloo) about 1.5 yrs ago and have been very happy with it. When I was setting up another shop at our new home in British Columbia (a home that came with a DeWalt 735 with straight knives) I was reminded of the reason for doing this. Using the planer with straight knives after getting used to the Sheartak head really highlighted the difference. So I ordered another helical head. It arrived within days. I installed it and it has been great. Much quieter, and much smoother results (far less tear-out). The internet is full of people saying a helical head is well worth the investment and I am here to agree. Sheartak has been great to deal with. Prompt and valuable customer support. Thank you.

Great product
This does exactly what it's designed to do. Installation could be a little rough if your not mechanically inclined and have a healthy tool box but it's doable if you take your time. The noise reduction alone is enough of a reason to do it. I do have a chipped cutting edge already though.

Good overall cutter
Install is straight forward, might need to rotate a couple carbide inserts after first few passes to correct any lines, otherwise good overall cutter

In spec and cuts well
It works really well as long as you take an hour or two and get the required tools for installation. They cut like any other spiral helical head with angular cuts, almost reduced all the tear outs completely.

Worth every penny
Bought a Sheartak Spiral Cutterhead for my Dewalt DW735 planer, and could not be happier with the results. The cut quality is super smooth, and does very well on highly figured, or woods with difficult grains. Cut through maple and white oak like butter.
I've been using mine for 4 months now, throwing 50-100bdft of lumber a week through it, and no signs at all of the blades becoming dull. The sound difference was not as overwhelming as expected, but that's more due to the blower fan on the DW735. The cutting sound has highly improved, but definitely still need hearing protection.
Do I need to replace the original bearings? If the bearings in your machine are in good condition, they can be reused by carefully removing them with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removal may cause damage. To minimize this risk, we recommend replacing old bearings with our greased and sealed bearings, designed for long-lasting performance. For a smooth upgrade, we suggest adding the bearings to your shopping cart before completing your purchase. We provide premium bearings from NSK, SKF, NTN, FAG, Timken. They are renowned for their high quality and performance, designed to provide durability and reliability in various applications
Do I need to to Add a Few Boxes of Carbide Inserts We provide 5 carbide inserts and 5 screws as spare parts. However, many of our customers choose to purchase additional boxes, as the shipping costs for separate purchases can make it less economical.
Do I need a Torque Wrench? To securely lock the carbide inserts, we recommend applying a torque of 48 to 52 Pound-Inches (or 5.42 to 5.88 Newton-Meters). (Note: 1 Newton-Meter is equal to 8.851 Pound-Inches, and 1 Pound-Inch is approximately 0.113 Newton-Meters.) It is crucial not to apply excessive torque, as this could cause the carbide inserts to crack or explode. On the other hand, using too little torque may result in the inserts not being properly secured, which could lead to cracks, shattering, or uneven height on the cutter block, causing ridges or lines on the board. If one person is responsible for maintaining the machine, they can typically apply the same torque consistently without a torque wrench. However, when multiple people are involved in machine maintenance, ensuring uniform torque application can be challenging. For consistency and peace of mind, we recommend using a torque wrench.
What kind of steel the cutter block is made of? The cutter block is constructed using GB/T 40Cr, a structural alloy steel of the same caliber as ASTM grade 5140, AISI 5140, SAE 5140, DIN 41Cr4, BS 41Cr4, JIS SCr440, and EN 41Cr4.The primary components of this steel are as follows: carbon (C) at a range of 0.37-0.44%, silicon (Si) between 0.17-0.37%, manganese (Mn) within 0.50-0.80%, and chromium (Cr) from 0.80-1.10%. In terms of physical properties, this steel exhibits a tensile strength range of 115-234σb/MPa, a yield strength of 2σ 0.2 ≥/MPa, and an elongation capacity of 65 δ5≥ (%). It also has a HBS range of 123-321 and a HRC rating of 30. This alloy steel is frequently utilized in low to moderately stressed components for machines, engines, and vehicles.
Why Choose a Spiral Cutterhead for Your Planer or Jointer?
Cleaner Cuts with Less Tear-Out
Spiral cutterheads shear wood fibers at an angle, unlike traditional straight knives that chop the grain and often cause tear-out—especially on figured or interlocked woods like birdseye maple or oak. The combination of staggered insert placement and shear cutting action leaves a silky-smooth, glossy finish, even on the most difficult hardwoods.
Long-Lasting Carbide Inserts
Each cutterhead comes equipped with premium 15x15x2.5mm inserts made from sintered tungsten carbide—more than 10x harder and longer-lasting than high-speed steel. Each insert has four sharp edges. When one edge dulls, simply rotate it 90° for a fresh cutting surface—no sharpening needed.
Quieter, Smoother Operation
Instead of the loud, aggressive chopping of straight knives, spiral cutterheads work with a continuous shearing motion. This significantly reduces noise and vibration, making your workshop more pleasant and less fatiguing to work in.
Improved Results on Difficult Woods
Whether you're working with birdseye maple, oak, or other tear-out-prone species, our helical/spiral upgrade delivers superior finish quality—perfect for both professionals and hobbyists.
Easy Maintenance and Replacement
Forget the hassle of aligning straight blades. Each carbide insert is precisely indexed for easy, repeatable installation. The cutterhead is dynamically balanced for smooth performance, and built to a tolerance of ±0.0004" (0.01mm). You can change a knife in minutes by loosening a screw, rotating the insert, and tightening it back down—no complicated alignment required.
Better Dust Collection
Spiral cutterheads produce shorter, finer chips compared to straight knives, improving dust extraction efficiency and keeping your work area cleaner.
Lower Long-Term Costs
With reduced tear-out, less sanding, no sharpening, and durable carbide inserts, spiral cutterheads pay for themselves quickly. They're ideal for both professionals and serious hobbyists looking for superior results and long-term value.
