Another winner from Grizzly with thousands sold since January 1987.

The Grizzly G1033 series has been smoothly churning out countless board feet of material on a daily basis since 1987. We are reintroducing this no-frills, all-performance classic version.

MONSTER PLANER! 05/31/2020 12:59:14 PM

Excellent as expected Grizzly quality. Super quiet with just knives in comparison to my DeWalt 735 with helical heads. Most impressed by this monster although I wish it came setup about 8 - 10" taller than it does. Wound up having to put 10" riser torsion box under it to bring tables to waste-height for me, I'm 6'4"

After a year of use... 05/29/2020 1:44:47 PM

I read a lot of out of the box reviews of products and they end up not being useful simply because the value of a product like this is not from the unpacking and setting up. It is from some level of prolonged use.

This is a 20 planer and it requires a bit of effort and time to set up properly. The beauty of a machine in this category is that you can make adjustments that cannot be done with a lesser machine like a lunchbox planer. As with any machine like this, that is an effort well worth the time expended. So do spend the time setting it up and doing test runs. Once you get this dialed in, you will have a planer that will give you an excellent level of finish with a great level of precision.

Once tuned and set up, this planer performs quite well and appears to maintain its settings. After a big run of wood, I usually check the adjustments (get a rotorcator if you do not already have one). I have made minor adjustments over time, but none that were unexpected or abnormal.

This a a 4 blade machine and it gives a very fine cut finish. Again, maintain and adjust your blades with care and you will be rewarded. I sharpen my own blades and did not find the replacement and resetting process a problem at all. As long as you are using the proper tools, you will be fine with this planer.

The feed has worked quite consistently. You do need to get the feed tables properly aligned, though, or you will experience in feed and out feed problems, especially with longer boards. Once aligned, the feeds work well with minimal snipe. You can also adjust the feed rollers on both the top and bottom, as well, and you should take time to make these adjustments in the setup. I have not had to further adjust these once they were tuned.

I have run thick and thin stock, long and short stock, a wide range of hardwoods from alder to ash, oak, and beech, and everything in between. Everything has come out as well as or better than expected, even some of the mildly figured woods where I was expecting year out (and did not get).

I have a 3hp Grizzly 2 stage cyclone dust collector hooked up with a 4 hose and it has worked quite well. One should make sure, though, that you have as direct and straight an air run as possible because this will blow a lot of chips up the pipe.

The wheel for adjusting the thickness has a very tight, positive feel with very little backlash. It runs very smoothly. I have, on a couple of occasions, forgotten to engage the table locks after adjusting the height, and it still held the adjustment during the run (though I would not make a habit of that).

I really questioned in the beginning whether I should get a planer this big before I bought it. Since then, I have been so happy I did this. This is a planer that will last beyond my lifetime. I work a wide variety of wood, mostly for cabinetry and furniture. The greatest benefit I have had with a planer this size is that I can run a wide range of boards and panels, plus multiple boards with a great deal of ease and precision. One must reserve a great deal of space, however, in the shop. One recommendation here, get a heavy duty caster set (I bought the Grizzly rig). I do not move it now, but if I ever need to rearrange the shop or even make minor movements (which I have done), it is a great thing to have.

This is a great planer. But it is a big planer (not a toy planer) with a lot of adjustments and capabilities to dial in for the finest woods, so give it the love and attention, watch your maintenance intervals, sharpen and/or hone your irons regularly, and you will get great performance in return.

This machine is very well built. Setup was very straight forward and took me less than two hours. Unless youre never going to move it order a mobile bas as well!

Get you one! 01/27/2020 12:25:00 PM

Does a great job. Has plenty of power and was easy to assemble and fine tune. I've planed white oak boards close to 20" inches with great results.

Great product 03/12/2019 10:32:32 PM

I bought this product over a month ago verified all the tolerances and added oil as instucted. All went very well from start to finish. The item was well packed when shipped. Did not have to do any adjustments after checking tolerances. Very happy with product I bought for my 50th birthday gift . I wish I would have bought it sooner so much quiter than my 13 inch bench top screamer. My neighbors noticed the differnce.
