Helical/Spiral vs. Straight Cutters

In planers and jointers, i know all about the rhetoric that the tool manufacturers tell us What I want to know is from anyone that has used both on similar tools and is there a startling difference and is it worth the extra money.

Yes, it's totally worth it.

+1 on totally worth it. I changed the cutter head in my jointer to a Shelix first but held off on doing the planer because of the cost and complexity of doing the conversion. After finally doing the planer, itís the greatest thing since sliced bread. If I were buying new, Iíd absolutely go for the Shelix head.

No more knife setting, no more knife sharpening, little to no tear out in highly figured woods, quieter.

Whatís not to like? (Other than the cost, but youíll forget about that in time)

What the others have said plus they stay sharp ten times longer. We used to have to have jointer knives sharpened 3-4 times a year and now we can get 3 years out of one edge. Planer stays sharp even longer. I'd never want to go back. We have the Shelix heads.

They are very similar, but ...

Read down toward the middle of this article and you'll see a paragraph "Helical vs Spiral" ......
https://www.wwgoa.com/article/spiral...upgrade-price/

The spiral cutters are parallel to the cutterhead shaft. The helical cutters are at a slight angle and shear the fibers better..... theoretically. That's the interpretation of the article for those who don't like links.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Shelix is a brand which uses the Shearing and Helical cutting pattern. It is IMHO well designed and well made.

And they are a lot quieter, I have a Grizzly 1033 planer that came with straight blades it was made before they helical heads caught on. With the planer and the DC fan running it was so loud even with ear plugs in it was too noisy, now just a little whirring noise

I know, I bought mine in about 85 and was $995 delivered, the Shelix was on sale for $850 when I bought it but it is worth the money in my opinion, it will flatten the gnarliest wood like glass almost, very very little tear out

I used to hate setting the knives in my jointer. Iíd spend hours hunched over it setting and re-setting the blades until they were all the same, then trying to get the outfeed table set properly. I bought the Shelix just so I wouldnít have to do it again.

When it came time to change the knives in my planer, I couldnít face it and bit the bullet and got the Shelix for the planer too. It cost about 2/3 of what I paid for the planer and it was a bear to install. Still worth it.

I have the Shelix head in my DW735. I didn't believe it was worth it for a long time, then I bought it, paid what I originally paid for the planer, and it was worth every penny.

Better quality of cut, massive noise reduction, handles end grain without issues.

I won't have a planer or joiner without one now.

I didn't notice very much noise reduction with my DW-735. Maybe I was expecting too much. I haven't put them on my jointer yet.

I have a 2 hp radial fan in the rafters above the planer, so it is also moving a lot of air, it sounded like a low RPM police siren but louder, it screamed
