These 4-row spiral cutterheads replace the standard straight-knife cutterheads on our Grizzly 8" Jointers. Equipped with 40 indexable, carbide inserts that can each be rotated three times for a new factory-sharp edge, you'll get much better finish and quieter operation, all with zero knife changes or sharpening. These cutterheads include cast-iron pulleys, bearing blocks and mounting studs, as well as 5 extra inserts, a T-handle wrench, Torx® bits and spare insert screws. These Grizzly cutterheads leave an incredible finish and are comparable to the Byrd® cutterheads in quality of cut as well as the quality of the cutterhead itself. The inserts are imported from Germany.

I installed this in my G0586 Jointer and I am very pleased with it's operation. Cuts are smooth and the noise has been reduced.

Easy installation and works extremely well 04/04/2020 1:18:21 PM

The installation into my Grizzly jointer was really easy as the cutter head came with the bearing and blocks already in place. It basically dropped into place. All I really had to do was measure to make certain the cutter head was parallel to the outfeed table. Easy with a feeler gauge. The finish left on the wood is silky smooth. I am glad I made the switch to the spiral cutter head, worth every penny.

I put this one my 8" jointer, and really like it. I was easy to instal, does a great job, and is quieter than before. I should have done this years ago.

I bought this a month ago and it works great. Gives a great finish on the wood. Wish I would have done it sooner.

I bought this as an upgrade to a 20 year old grizzly jointer. Works great

Very simple to install. Surprisingly quiet...I had read other reviewers mention that but it is very easy on the ears comparatively. I work with figured wood about 90% of the time and it leaves a fantastic ( tearout free ) surface. Well worth the expense!

Good Purchase 01/10/2018 10:15:08 PM

The included instructions were clear and simple. The installation was simple and straightforward. After making the required adjustments I was jointing test boards within 1 hour of starting the whole process. The surface finish was as expected and satisfactory.

What an upgrade! 06/02/2017 4:13:12 AM

I changed out the cutter head on my GO526 and couldn't be happier. The new head even came with its own bearings and bearing races, so installation was a breeze. Old one out, new one in, much easier than even the Grizzly video. I've run a few thousand linear feet through in the first few months and haven't noticed any lag. I'm very happy I made the switch.

Go ahead and make the switch 03/12/2017 1:36:18 AM

I just installed this cutter head and it was very straight forward. To say I am an amateur mechanic would be an overstatement. It took two hours and the new cutter head went in without a hitch. The old cutter head needed a shim but the new one did not.
If you are procrastinating as I was because I was intimidated by the installation process, don't be. My hat is off Grizzly.
The finish on the work pieces is so good, it is well worth the money and installation time.

I knew this would be a good move. 01/31/2017 4:43:17 AM

I bought this cutterhead in Dec. 2016 for my jointer. I knew beforehand that it would be fantastic, because I upgraded the cutterhead on my 18" planer a couple years ago. Install was straightforward and went without a hitch 'cause Grizzly includes everything you need for the swap out. I have already put several hours on the new cutterhead and yes, the smooth is worth it. No knife marks whatever on walnut, maple, pear, or even madrone. Impressive!

good product and excellent value 01/26/2017 2:35:28 AM

Having the pulley and bearings per-installed made installation a snap. The cutter head appears to perform as advertised.

I purchased this cutter in December of 2016. Cutter arrived well packaged for shipppng and initial handling. Installation was easy, and for my machine it required no shims. The finish was as good as the Grizzley tech told me it would be. Wood that had fine tearouts with my old cutters was re run with the new cutter and tear out was gone. Even crotch grain was cut without tear out which was a real plus. Would recommend.

Fits ENCO 150-5100, Super smooth, Excellent! 01/02/2017 10:25:15 AM

I bought this to run in my ENCO 150-5100. Its an exact drop in replacement and fits perfect! These things live up to the hype. I ran a bunch of red oak through and it came out smooth as glass! Thanks again Grizzly!

I just replaced the original cutterhead on my Grizzly G0500 8" jointer with your spiral cutterhead, H7654. After running 40+ board ft of curly maple, I can say this is one tool that lives up to its hype. Not only did I get NO TRACE of chipout on face or edge cuts, but the faces actually look like they've been sanded! This will save many hours of sanding, and is truly one of the happiest tool investments I've made in 30 yrs of woodworking!

Kudos, and thanks!
