I can not speak to a Shelix, since I don’t have both heads in my shop, but I can speak to the Grizzly – it eats would like a well behaved guest.

As my review of my eight inch, long bed Grizzly jointer indicates, all the wood I ran over my jointer was highly figured, but came out the other side with little or no tear out.

I’ve got the Shelix but not the Grizzly. Based upon what others have said, the shelix cuts better but the difference is pretty insignificant. What may matter however, is that Byrd uses industry standard inserts while Grizzly uses proprietary inserts. So the Grizzly head will be cheaper to purchase but replacement cutters for the Byrd will be cheaper. That’s not a major issue for most hobbyists who will probably never use all 4 edges of the original inserts.

Thanks for the feedback guys. You think a $260 upgrade is worth it? I feel like it is when it comes to figured wood. The shelix is actually cheaper in this case because the 6” Grizzly comes with the bearing blocks and pulley wheel while the shelix is just the cutterhead using your existing bearing blocks and pulley. I have no issues with using the existing as I refurbished my jointer from the ground up and know how to take it apart and put it back together.

Buy the Shelix! I have both an 8” on my joiner and a 15” on my planer. As I understand it, Grizzly inserts are square and Shelix are radial—the joiner and planer heads are round, not square. But, in reality it makes very little difference. My main reason for choosing Shelix is that it is made in America and Grizzly is made in the European rim (or some other foreign country if cheaper).

The different cutter heads can have a differing number of inserts or insert rows. I am not sure whether that is the case for the Grizzly and Shelix comparison at hand. By my way of thinking if one cutter head offers more rows of cutters it would seem to me that one perform better and stay sharp longer. With n more rows, it would seem each cutter would work a little less and produce a few more cuts per rotation than on a cutter head with fewer rows.

I really cannot say whether the $260 upgrade is worth it. However, I recently made the switch from straight knives to spiral cutter heads. In addition to reduced tear out and less noise, advantages frequently touted, I found that it seems to require less force to feed the stock. This is handy at the jointer when face jointing a board. The push pads seem to slip far less and require a little less downward pressure, making for better results than with straight knives.

The surface off the jointer and planer after using the spiral cutter head is slightly rippled. A little light sanding gets the stock ready to finish. This was a concern of mine when I made the switch but turned out to be a non-issue. The sanding required on stock milled with the spiral cutter head actually seems to be less than with straight knives. The straight knives seem to develop micro nicks which leave the stock a little rougher than with the spiral cutter head.

The last advantage of the spiral cutter head is that the cutters are carbide and thus should stay sharper longer than HHS straight knives. Thus, more bf can be milled before a cutter change is required. I personally hated to replace and thus reset the straight knives. It also seemed to take me a long time fiddling with the straight knives to get them perfectly set. However, I suspect that replacing/rotating all the cutters on the spiral cutter head is not as easy as it is made out to be. But if done properly, setting the height of the cutters is a no brainer.

I have the Shelix in both my jointer and the planer, so I can’t compare them to the Griz. But everything I’ve read and heard (from owners) makes me think performance wise there isn’t much difference. I do think the points made about the Shelix (USA, radius edge, etc.) are worth something….to me it would be worth more. Is putting one on worth $260? To me it is, just the noise reduction is worth it, not having to screw around adjusting knives (especially on a jointer) is another big reason.

I put a shelix head on my dewalt, it was the best investment I have made in woodworking machinery ever!

Not to derail the OP, but I had a couple of questions along the same line of questioning:

1. How do I get a 10% coupon for Grizzly? Mailing list, catalog, make an order?

2. I’ve got a Delta 37-190 and have kicked around the spiral cutterhead. It’s not super difficult to set the knives or shift them for a nick, but I use it a lot and indexing cutterheads sound like a plus for me. Does anybody know if the 6” shelix on Grizzly’s site fit the 37-190? I did a bit of searching and while I know that a lot of these jointers are essentially clones, I can’t seem to find anything that would give me confidence the 37-190 matches any of the jointers on the supported list for the Shelix (or Grizzly) spiral cutterhead.

I have the Grizzly cutter head on my 6 inch Ridgid jointer. It was surprisingly easy to install, which made me very happy. It cuts great. I have rotated the square cutters one 90 degree turn in the past couple of years. The cutters hold up great.

Grizzly has good info on what heads fit your jointer.

Thanks for all the feedback everyone. I pulled the trigger on the Shelix. I look forward to getting it installed and see some awesome results. :)

Have your say...
