Made in the USA by Byrd®, these indexable carbide insert cutterheads are very well made and leave a great finish. The inserts are positioned along a spiral pattern, and rotate at a slight angle for a shearing action that leaves a glassy smooth cut on the toughest of woods. Comes with all 75 inserts on the cutterhead, plus 10 extras.

This is worth the money!! Do this upgrade as soon as you can 03/26/2019 5:47:59 PM

So, I ordered the W version of this. It's wrong for my planer. Grizzly was AWESOME to deal with and we got everything squared away with one phone call. New cutter arrives and I get back to putting it all back together. I will say this. The video out on YouTube from Grizzly does kind of glaze over some things. (https://www.youtube.com/watch?v=vBwmzacZFSs) This is a simple enough job that most people can do in a couple of hours. However, some things to note.
1) You only get the install instructions if you purchase a Grizzly cutter.
2) They skip over when you pull the gearbox apart that the gears just pop out, so it's OK to give them a little tug.
3) The separation of the cutter head and the gearbox - don't leave the bolt in as shown - you could bend it (so a friend tells me - HA)
4) Filling with gear oil - no one ever says how much oil to put in. That would be nice to know. Plus - as shown in the video (on its side) the oil will leak out of the four opening in the top.
5) With the reinstall of the V-belts means you had to take them off - they explain that. TIP: leave one nut in place so you will know where to tighten the motor back down to.
Other than that - it's a good reference video!

Great product 03/16/2019 4:45:46 PM

I purchased this cutter head on 3/9/2019 and it's the best thing I did to improve the quality of milling my rough lumber. I couldn't believe how smooth the face and side of the wood was. Now, I just ordered the cutter head for my planer. Thanks Grizzly for allowing me to upgrade my old jointer (G1018).

awsome cutter head, whish I would have done this a long time ago! 01/25/2019 3:49:48 PM

I received cutter-head, put it in easy, and it works great, cuts smooth and is quiet. I only wish that bearings and gasket were included in the order, or at least suggested.
thanks for a great product.

Installed on 15 year old Delta 3 hp DC380. Pretty simple installation. I have seen noise level measurements on you tube but I can assure you the noise level is cut in half. Looking forward to not have to set knives anymore. While its a pretty expensive upgrade - it is cheaper than buying a new planer with preinstalled Shelix head.

great upgrade 12/29/2018 3:52:37 PM

Very pleased with this upgrade! 10/27/2018 1:44:52 PM

I installed this cutterhead in a Yorkcraft 15" planer that, except for the paint, is absolutely identical to a Grizzly G0453. Grizzly has an excellent video tutorial on YouTube on how to perform the swap. Being a woodworker and not a mechanic the process took me over 3 hours, but everything went off without a hitch. I am thrilled with the change in this machine. The noise level is much much lower and the quality of the cut is just excellent, even in heavily figured wood. I highly recommend this upgrade.

Great upgrade to my 15" planer. Biggest suprise was how much it reduced the noise levels. While not suggested, you could run the planer without hearing protection.

Wow what a difference!! The cutter head was delivered in two days, was well packaged and installed in about two hours. The noise level with the new Byrd cutter head was greatly reduced. Almost dont need hearing protection. Although I still recommend you wear it. I ran about two hundred board feet of ash through the planer and the surface finish was like glass. I almost felt that sanding it with 220 grit would roughen the surface. Wish I would have installed it a long time ago.

Great cutter 03/15/2018 12:01:20 PM

Byrd cutterhead turned our planer into different tool. It's much quieter now and there is less chip out.

great product, should have purchased it a lot sooner. machine runs smoother and dust collect hasn't plugged up since spiral cutterhead was installed.

Older G1021 Planer 01/28/2018 3:40:28 AM

This fit great in the G1021 15" Grizzly planer made in 1991. Had to freeze it and heat the bearing to get them to slide together but works incredibly well. Bought the 20" version for my dads I love it so much.

Great upgrade for my 15" Jet Planer 08/13/2017 2:28:14 PM

The Shelix Cutterhead is worth every penny I paid. My planer is so much quieter, I can almost plane lumber without ear plugs. The boards come out so smooth it is almost like they are already sanded.

Expensive upgrade but worth the price 08/04/2017 1:25:08 PM

First, Anyone considering the purchase of a new machine should not hesitate to spend the extra money and get the helical head model. I purchased my planer due to the closeout price & made the decision to buy the Byrd shelix head a year later. The installation was not difficult & I took the time to correctly set the infeed & outfeed rollers, pressure bar & tables. This difference in the reduction in noise and quality of cut was amazing! Everything other reviewers said is true!

Lastly if you make the decision to do this upgrade be careful taking the cutterhead out of the box. The thing bites! Be sure & wear gloves & wrap the cutter head in cardboard or construction paper so you don't cut yourself.

Installation was not as simple as expected inasmuch as the sundry videos did not detail the way the gearbox disassembled, particularly the business end of the cutterhead. I replaced the two main bearings at the same time which took some ingenuity to put on without straining the ball cages on a 15" shaft (my bearing splitter will work as both a puller and a press for bearings on the 9" long shaft on my jointer). However, once installed, I couldn't be more pleased with the results. A superior surface, better chip extraction, and no real need for hearing protection (the spinning motor is louder than the cutter to wood engagement). It was a worthwhile purchase.

The shelix cutter put new life into my old planer. Much smoother and cleaner that I ever got with straight blades. Watch the YouTube video on installing them to make sure this is something you can do. Not hard, but it takes a little time, and you have to pay attention. Results are well worth it!

Great Upgrade 01/27/2017 1:19:29 AM

Shelix cutter head is an awesome upgrade to any planner.
Very smooth cut with no tear outs. Installation went good, just need to take your time. Grizzly has a good video on how to install.
Good thing is no more knives to mess with.
Grizzly staff did an excellent job matching up the right cutter head to my old planner.
Well worth the money.
