Super product 01/22/2020 12:30:41 PM

I planed more wood in 1 day than I planed in the last year. That is because this cutterhead worked so great that I enjoyed planning, I put the boards in & walked to discharge end & waited for finish. Before it was a chore to plane boards. Bonus is that it is also considerably quieter. I wish I had done this years ago. I can't say anything about the durability cause I just bought it, The installation was a little challenging but doable. The Byrd website has pretty good instructions. The shaft on this cutterhead is slightly smaller than the original so L bought one locally & replaced it.
I wrapped the cutterhead in some thin heavy cardboard to avoid damage to head or me.
If your buying new planer, I would buy it with the spiral cutterhead no doubt.

Good cutterhead.... excellent cut 01/05/2020 4:55:09 AM

I bought this to upgrade my mid 90's Bridgewood planer. The install was fairly involved and I had to change the seal in the gearbox to another size that fit this head. Make sure to check the sizes, or you could be pulling things back apart. The cutter is one of the best upgrades to a planer!

It fit my Reliant DD37 15" planer 07/12/2019 1:37:40 PM

I found a link online of a person who said this cutterhead would fit the Reliant 15"
I took a chance and ordered it. It replaced the old 3 blade head exactly and with new bearings it
does a terrific job and the smaller chips don't plug up my vacuum system.

great product 07/08/2019 4:21:41 PM

Put this on my machine which reliant 15" dd37 and it fit perfect.

Nice upgrade 12/06/2018 11:01:28 PM

This was a nice upgrade to my planer. Shortly after sharpening my blades about a year ago, I nicked them again. After seeing a couple of reviews on spiral cutter heads I decided to upgrade basically from the sheer ease of rotating one of the carbide inserts to repair a chip. Excellent instructions are included but be prepared to spend more time than the 3 hours stated. I had a problem removing the bearing on the gear box side of the shaft. It was a real pain but I was finally able to get it to release. Grizzly customer support was excellent, they recommended replacing the bearings, seals and gearbox gasket... and that was a good decision since I ruined the one bearing when removing it and I don't EVER want to open this machine up again because of an oil leak or noisy bearing. The cut is great and the chips that are produced make it easier for my dust collector to remove them (another big plus for this upgrade). I was so sick of the chips clogging the outlet... this upgrade will be worth it for that reason alone!!!!!

excellent product made in the usa 10/04/2018 12:13:38 PM

the noise level is greatly reduced and in my opinion by at least 50% - the shavings are much smaller making it easier to clean up

Spiral cutter 06/09/2018 2:00:52 PM

The difference in the spiral cutter over the conventional cannot be overstated. The finish is excellent. An added bonus is the noise level is half what it was before.

I ordered this in October I didn't get it till January this is the only dissatisfying part about dealing with grizzly on this product the product works fine it just took forever to get it in and I did not always get satisfactory answers from people when I would call up there to find out where it was
