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.

I just installed the the new Spiral Cuterhead on the Logosol Moulder and did to first couple of passes, wow, what a great finish and way less vibration.
Great Product.
Thanks

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.

The cutterhead made the dewalt 1161 a completaly different Machines. Better then new. Simple to instal

Much quieter than blades. No messing around with trying to align the blades to the outfield table. Very smooth wood at the end of jointing.

Installation was a piece of cake but..
The issue was aligning the outfeed table. With the PC 160 JT there is no adjustment for the outfeed table. To align it I had to sand some of the cast aluminum flat.
Once that was done it set up easily and cuts smoothly and leaves a smooth finish.
I am please with the results.
I don't have a bearing puller so, I purchased the extra bearings just in case but I didn't need them. The old bearings came off the old cutter and on the new one very easily.

Works so much better than the stock 2-blade setup. Noticeably quieter. Be careful on the install, the Sheartak Youtube video has some unnecessary steps (removing gearbox), and also doesn't show everything, there is a forum post that that is a bit more comprehensive.

Overall would recommend, excellent surface finish when taking 1/32" cuts on maple. Not sure what max depth of cut would be with this compared to HSS knives setup.

Excellent tested on white oak and superior to the hss blades. Much quieter

Worked, glad I purchased to remove the bearings

Hello colleagues
The discussion about whether or not to buy a spiral shaft is already several years old. Fake shafts, which only have split blades but are not mounted at an angle to the running direction, are flooding the market. Shafts where you have to file away a piece of the housing also seem normal.
Here, however, we have a genuine spiral cutterhead as the inventors at Felder and other companies thought of the principle. 14 degree angled blades that make a pulling cut possible and a shaft that has been designed in such a way that it can be easily installed without manipulating the housing. The shaft runs 5 decibels quieter and with a much more pleasant sound than before. The cutting pattern of the planed surface is almost perfect and no longer needs to be sanded.
The shaft has 40 knives, which is roughly the same as the cutting edge of the original shaft. Perhaps 52 knives would have produced an even better surface and Mike, who does a wonderful job of support, is thinking about offering a shaft with 52 knives as an option.
I am very happy with the shaft and can recommend it without reservation.

I bought it from France and received it very quickly, with excellent packaging. Installation was pretty easy.
It's simply smoother, quieter, and has a much better finish—truly a night and day difference compared to my old cutterhead.
I should have bought it sooner! It's pricey, but definitely worth it.
Thanks a lot, Sheartak!

Received in a timely manner. very well packed. Installation was relatively painless. Did have to take table off of the legs as bearings were held down with studs and not bolts. Simple job, loosen nuts then unscrew studs. Made one mistake putting on bearing holders as it's difficult pulling bearing and block out for proper spacing w/o removing carbide bits. I'd install spacers between cutter body and bearing next timd to ensure proper spacing. Be aware that the head has to be centered with the table or it will jamb on the table frame.
Replaced belt at the same time as I had it all apart (A-42)
It's a little noisier than before, but does a very fine job no matter which way the grain is going, even over knots. Noticed very minimal tearout on spruce boards. Haven't had a chance to try it out on more exotic woods yet.

Quality of manufacturing seams to be excellent. Packaging was superb. Just ran a ton of maple with no issues, smooth as can be with virtually no tear out. Nice that they come with a few extra knives and a wrench. Bearings and seals fit perfectly also. Purchased another for my 8 inch jointer. Highly recommend these heads, just as nice as byrd but less expensive especially in these times.

Cuts effortlessly and leaves an outstanding finish
Takes a few times to adjust the depth properly, and get used to the new and minimal sound when cutting

-less effort required to pass material over the jointer
-super clean and tear out free surfaces

Well worth the money for me!!

Thank you Sheartak

A lot less noisy and a very good finish. Note that if the bearing case are not perfectly parallel to the tables, you may have to shim the lowest bearing case since you won’t be able to compensate with the adjustment of the knives anymore. This happen on my General 1180.

I was excited to try an indexable cutter head.... It did not dissapoint.... one of the best purchases for my little shop - easy install.... clean cuts, quieter, easy dust collection.... I have nothing bad to say .... I am doing a Oak table, my jointer handled easily... while my planer struggled... will be ordering one for the planer as soon I can afford......

Produce a wonderful finish and better chip removal from planer.

They leave a beautiful finish, so far i've only used them on Teak and the finish is awesome.
