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.

DW735 Cutter Head

Installed my cutter head almost a year ago, very easy install into my DW735. To date I have not had to change any of the carbide cutters and still get a perfect finish. I would have used multiple blades of the original design. The best upgrade!

Very Happy with Sheartak

I am very happy with the product and my experience with Sheartak. The head itself more than meets my expectations and produces an excellent finish on any wood I have used it on. The smaller chip size it produces works much better with my vacuum system as I have not experienced any blockages as I did with the long chips produced with the original cutters. It was easy to install.

I had an after sale request, which had nothing to do with any fault of the product, which they handled with no fuss and were very accommodating. I have nothing to say, but good things in dealing with Sheartak and have no concerns in recommending them.

A worthy upgrade

Installation was easy, but I made it harder than it needed to be. When it was time to put in the new head, I hit the threaded end to align it without putting back the pulley first and I damaged the threads. No big deal though, I sent it to a machining shop nearby and they fixed the threads. After installing it the right way I torqued each knife to spec I tried it and the results were very good, but I had some vert small lines showing. After realigning some of the inserts the boards came out so smooth I understood why people go crazy about these heads. When looking at the boards under light you might see some lines on them but you shouldn’t feel them with your hands. It shouldn’t matter though if you sand your projects, and it is galaxies better than the nicked straight blades I was using (I am kind of lazy about blade changes). I took the same 1/16 passes I usually do and the motor doesn’t seem to be working significantly harder than with the standard head, time will tell if the motor likes the upgrade or not. Noise is reduced but you absolutely will need ear protection anyway. Hard maple usually teared out a lot with the last set of straight blades I had, and the maple test piece came out flawless.

Overall very satisfied, after three years of buying straight knives I feel like this cutterhead is going to save me some money and tearout induced headache.

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
If you add the bearings to your order, we will preinstall them for you when premounting is possible, saving you the hassle of doing it yourself.

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.
