Hi;
Just in case, I bought an extra box of 10 of the carbide inserts;
If required, I'll use them in my jointer and planer;
They now both have Sheartak spiral cutter head;

They both work extremely well, and I'm very happy I bought it;

Thanks
Sylvain

Hi;
This torque wrench is almost a must (unless you already have one) in order to make sure the carbide inserts are installed acurately;
The only thing I would have appreciated is an extension between the ratchet and the socket;
By experience, I can say that is quite difficult to access some of the screws;
With a jointer, no problem, but with a planer, it's more difficult;

Thanks
Sylvain

I have a 40 year old 8 inch jointer. Its is a great machine with one downfall, straight blades. So I contacted Sheartak and they were a great help finding the correct cutter head. I have just installed it and the difference is unbelievable! Thanks for all the help from Lucy and the Sheartak team.

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

Love our Sheartak, it's now tackled quite a bit of rough and reclaimed lumber, and much of it end-grain passes on walnut and rock maple cutting boards, a bunch of super hard ipe, just now, over a year after install, I'm turning all the inserts 90 degrees. Does such a clean job no matter what kind of mess you send it. Bogs a little easier than before but not enough to complain.

Ordered on a Friday and arrived at my UK address within 72 hours. Expensive carriage but very fast delivery.
Two hours to remove the old cutter head and install the new one. It was a direct replacement for the original, three knife, SD310 block.
A really great quality product, very well made and worth the investment.

100 % satisfied with product and service. Thankyou
A parts blow up of cutter head would have helped the install. I found one on line. Thankyou for not sending two sets of berings, my mistake on order form.

Hi Lucy;
Thanks again for all your help on selecting the correct SKU #;
I was a bit scary at the beginning, having to provide shaft diameter at both ends and lenght, bearings #, etc... but everything went extremely well;
Received it 5 days after the order;
Bearings already installed on the shaft made it very easy to install;
It took me longer to readjust the infeed and outfeed tables;
Now that it's done, I have to say I'm extremely happy with this spiral cutterhead;
Less noise, and the finish is awesome;
Thanks again Sheartak team for providing such a great product;

I use this to shape surfboards and it makes a much cleaner cut than my last drum. It allows me to move faster and hand sand much less. Thank you guys so much!!

Changing the head on my jointer was very easy. Service on line and at the shop was amazing. Will shop here again, soon.
Thanks

Very pleased with the quality and the extras (tool and blades). It fit perfectly in my King 6" jointer. I must say, my expectations were more than met. Very pleased with the results. Thank you Sheartak!

The machine now works perfect cutting even the thinnest slices of any type of wood. I regret I did not do this long time ago (because I did not know it was possible...)

I got this cutterhead because I had to replace the knives and like the idea of just replacing the square on the spiral cutterhead. the install was easy I use a halt round file to be able to install the cutterhead did a better job compare to what they did on the video. the cutterhead did a great finish on the wood and the machine is less noisy compare to the regular knives

OEM Cutters for these planes are difficult to find and expensive. This is such a better option than risking it on ebay for a used cutterhead that no shop will resharpen.

I ordered it from Canada, and it arrived fairly quickly. There were some additional costs for importing it into the EU, but it seems to have been worth it. It works excellently, the surfaces are much smoother, and it operates more quietly.

Great product! It arrived quickly and work perfectly!

Good price. Excellent performance. Easy install.

After installing the butterhead on my jointer the experience can be summarized in two words: smooth and quiet. The jointer delivered very smooth cut surfaces at a significantly reduced noise. In fact, the dust collector makes more noise. This is fantastic upgrade for a used machine.

I've never left a review on anything before, but this planer head for my 40 volt makita planer is too good to not leave a review!!
Seriously improves the cutting ability and speed! Its a lot quieter cutting too! Best upgrade ever, in my opinion!

replacement screws always a must . These are high tensil steel torx head , that work great

I bolted this six-spiral beast into my old SCMI S52 and—no exaggeration—the planer now sounds like it’s humming a cosmic mantra while atomizing tear-out into confetti. Feed a gnarly board in, and what comes out the other side looks kaleidoscopic: shimmering, glassy, and flat like it’s been politely negotiated into perfection by a thousand tiny diplomats in carbide suits.

This head is psychedelic in the best way—not trippy, just transformative. The cut is quiet-er, the chips are tiny, and the finish is so clean it feels illegal. Western hemlock with squirrelly grain? It shrugs. Edge banding knots? Yawn. The six-start helical pattern keeps the bite constant, so the machine doesn’t lurch—just a smooth, relentless zzzzzzip as the work glides through.

Is it scary? Absolutely. It’s a beautiful monster. Treat it with respect and it rewards you with:

No drama, no tear-out – even on cranky grain.

Sweet, steady feed – fewer vibes, more control.

Low maintenance – rotate the inserts, keep cutting like a boss.

Bottom line: this isn’t just an upgrade—it’s a planer rebirth. If your S52 still has straight knives, you’re living in black-and-white. This head flips the switch to full technicolor. Buy it, bolt it in, and prepare to grin like an idiot at boards that look too good to sand.

Very happy with my decision to buy these new cutterheads for my Hitachi planer/jointer. Installed easily and improved results.

The cutter fit perfectly into machine, there is a noticeable difference in the quality of the cut compared to the standard cutter that came with the machine. It is also a bit quieter. This cutter is worth the investment .

Absolutely increible set!!!

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.
