G1033X 20" 5 HP Helical Cutterhead Planer

Made to handle your toughest everyday use.

We took our G1033Z 20" 5 HP Planer and made it better by including a helical cutterhead. The 4-row helical cutterhead produces ultra-smooth finishes and greatly reduces tearout in figured woods. The 92 indexable carbide insert cutters can each be rotated three times to expose new, sharp cutting edges.

The G1033X incorporates a safety magnetic switch for overload and power failure protection. The power controls are mounted on an attached pedestal for easy access.

The power is transferred from the 5 HP motor to the cutterhead by a triple v-belt design. This ensures maximum power connection between the cutterhead and the feed drive.

The solid cast-iron, extension tables make the total planer bed length just short of 5' long! They are precision-ground to a mirror-like finish for ultra-smooth lumber feeding.

The adjustable bed rollers keep the planer feeding smoothly. The feed rollers are driven by a two-speed gearbox at 16 FPM or 28 FPM.

Like all Grizzly planers, the G1033X comes with a 1-year warranty which covers parts and assures the unit is free from factory defects. (Consumables are not covered by the warranty.)

The G1033X manual was written by our U.S. based Technical Documentation Department and is packed with useful information.

The Grizzly Customer Service and Technical Support Teams are U.S. based. Parts and accessories for the planer are available on-line and shipped from the Grizzly parts warehouse in Springfield, MO.

I have been using this machine for about a month now and am amazed at how quite is is compared to the 15" Grizzly I was using with 3 blades. I have been able to flatten strips of maple down to 1/8" even couldn't do that with the old one

Stellar Machine! 10/11/2020 6:42:19 PM

I currently own Powematic, Jet, and Laguna machines. I was a little skeptical of Grizzly tools, I thought they were the cheap knockoffs of the Big brands in the wood working Industry. I needed to upgrade my planer from an old Makita machine that has given up the ghost. I did due diligence on researching a new planer, but could not see spending the extra $1000 on a big name machine. I kept coming back to the reviews from other customers concerning Grizzly machines. 95% of the reviews were positive and I figured that other woodworkers cant be wrong. I decided on the G1033X 20 planer. First off, the freight was quick, nor was there a scratch on the shipping container. My son & I set up the machine in under 2 hours. Once we hooked up dust collection and power we ran a piece of white oak through it. Its super quiet, and the finish is literally smoother than 120 grit paper. I am absolutely delighted with my purchase! The fit and finish is equivalent, or better than other brands. I will be purchasing Grizzly tools in the future. 10 stars!

Does what it should do 10/02/2020 7:41:32 PM

Ran 4,000 feet of slightly dirty 1X12 walnut, cherry, hard maple two passes before knives started to dull a little. 8,000 feet of cutting seems awfully nice!
Tearout is negligible even on highly figured wood.
Love this planer.

Beastly Planer 09/18/2020 1:02:01 AM

I bought this planer about two months ago and it is awesome. It is a super upgrade from my Dewalt 13" benchtop planer. I checked the setup of everything as soon as it was unboxed and everything was right on. It has plenty of power and I have had no tear out on a few hundred board feet of red/white oak, walnut, and ash. It is significantly quieter than my benchtop planer too. My only complaint is that the bolt holes to attach the outfeed table to the main table were not tapped. Lucky for me I had the right size tap in my shop or it would have been a bit more of an inconvenience. Also, one minor thing to note is that there are 92 inserts (4 rows of 23). I have seen in a few places on the Grizzly website where 96 inserts are mentioned. The planer came with an extra pack of inserts (10, I think) and a lot of extra insert screws. It would be nice if the planer came with a 5-to-4 inch and 5-to-6 inch dust collection adapters. I'm not entirely sure, but I think most people set up a 4" or 6" system for dust collection.

I love this machine !!! 08/29/2020 3:07:21 PM

I purchased this machine about one month ago and absolutely love it !!!! It's quiet , powerful , and planes super smooth . It has cut down sanding time 2/3 . I have much less waste now that chipping is a thing of the past. I replaced a 12" powermatic straight knife planer with this unit and there is no comparison . I would highly recommend this planer . I have been in business since 1954 and this machine has made my job so much easier !!! Also right out of the crate the machine planed beautifully !!! No adjustments were necessary and not a scratch on it !!! Thank you Grizzly for a great machine !!! Dave , Matteson Kitchens LLC ,Greencastle ,Pa

Excellent piece of equipment. 08/28/2020 11:33:06 AM

Purchased this planer about a month ago. It arrived in mint condition and set up was quick and easy. It gets used daily and a couple hundred feet of quarter sawn oak later this machine has performed flawlessly. Fast, smooth, quiet. For the price it has exceded my expectations.

Hi, My recent purchase of the G1033X planer exceeded my expectations. The fit and finish was excellent. I know the ISO standards are higher than average but this was surprising. Great machine. Thanks, John

Smooth, powerful, and quiet 05/08/2020 2:34:18 PM

I have been looking for something better than my dewalt 3 blade. I work mostly in mesquite in which the grain runs in all directions which means the front end of a board may have the grain different from the back end. My dewalt would chip and tearout every board. This helical planer can handle all that to the extent that its smooth enough that no sanding is needed. My first project was a 3-d cutting board of mesquite , walnut, and maple with the grain of all 3 running in different directions, plus it was over 15 inches wide. This planer was able to handle it easily and quietly. I always put ear protection with my little dewalt but this planer is so quiet, about as quiet as my hand held drill. It's a very heavy machine so its a good thing I have a front end loader on my tractor. As soon as Grizzly finds a better way to put in gear oil I'll give it 6 stars.

Grizzly is the best company to work with 12/17/2019 4:01:38 PM

I bought a G1033X 20" planer from Grizzly. It was on back order. They communicated very well with me on when the delivery would be made. They even recommended the type of base I should use for this specific planer. I received the base first and assembled it. When the planer arrived they were very helpful and efficent because I had alot of questions for them. Their technicians are very knowledgeable and willing to help. I was very satisified with their level of service even after the purchase was made. I would highly recommend anyone to deal with this Great company. They did a wonderful job.

Great Product! 09/26/2019 11:38:48 AM

I sold my 20 year old G1033x planer to upgrade to this G1033x for the spiral cutter head, the 5hp motor to accommodate the cutterhead and the extension tables. Same sturdy machine with the added benefits! I'm expecting that this will be the last planer I will need to buy.

This planer is so quiet and does a silky smooth finish right away ! I picked it up at the freight dock rather than have it delivered because I felt getting it off the back of the truck would have been difficult! Once I got it into the shop setup was easy. The shear weight of this planer made me glad I bought the heavy duty base for moving around the shop ! Im so glade I got the 20 model! Wow what a beast !

I've had this up and running in my shop for a few weeks now and it's awesome. I've run cherry, white oak, maple, and poplar panels through it and they all come out glassy smooth. The feed and bed rollers and pressure bar adjustments are easy and intuitive to make but you'll need a digital indicator or a rotocator to make them accurately.

My only complaint is the location of the of the plug for adding oil to the gearbox.

Great machine so far, great price too.

big improvement over my 12 inch planers 12/28/2018 12:50:31 AM

Bought this 20 inch planer about a month ago and finally was able to get it into my workshop. The 900 lbs of shipping weight is no small item to move around. Needed a pallet jack to move it from driveway to workshop. Workshop is five stairs up and had to seperate the machine from motor and base to make it more managable. Everything came apart and went back together pretty easy. Had to use engine lift to get it off of base and on metal ramps to slide into shop. Once in shop, was easy to lift once again to reassemble top to bottom. One screw that holds control button box on, was damaged and stripped. Accessories weigh about 75 lbs, but the hood and handle went on very easy with hardware and tools provided. Kit also comes with ten extra spiral repacement blades and tools for replacing them. Still have to assemble bed extensions and hook 240 volt power to run machine. Remember to check oil level before using machine too. Bought shop fox base, but this item does not really give much clearance for machine to roll, could have had bigger wheels to get more clearance. We will see how well it planes when im done. The table glides up and down so much easier than any 12 inch planer I have ever used. I expect a lot out of the 5HP motor as well as spped adjustments for board feed.

Great Planer 10/06/2018 2:44:04 PM

I don't have anything negative to say about this machine. I love it. It's powerful, smooth, vibration free, and quiet while running. I have full confidence in its abilities and it performs as expected. However, like I stated in my jointer review, the shipping situation could definitely be better.

Works nice, very clean finish to wood 09/05/2018 6:40:36 PM

Thanks for going the extra mile and sending second machine when freight company lost first one. One point though, pallet too small to be used by hand forks making it difficult to unload. Maybe turn pallet opening 90 degrees.

Purchase was made a few months ago. I picked it up at the store a took it to the shop. Set it up with the book after placing it on the roller stand. Had some issues after it worked after a few weeks. The Tech Support was great and helped me address the issues.These guys are great. I got frustrated with the device but they remained calm and professional.This service is worth a lot because you have expert help.
This machine is quite, powerful and I found you have no need for sand paper. If you feel the need to sand, you can because you can always run the wood back through the planer. I work with cedar(rough cut) and this planer saves me time and money. I love it. This is not a toy, it is a professional grade planer and will exceed your expectations. With any complex device you have to learn the device and all of it's adjustments. The Tech Support is better that most and may give you peace of mind. If you want a planer, this is the one to buy.

Super Impressed 08/01/2018 12:26:37 PM

I bought the planer on a Saturday and it was at my door on Friday. Well boxed and went together in about 1.5 hours and that was with putting together the roll cart for it. Check the fluids, added oil and leveled the infeed and outfeeds and it is good to go. Have run oak, maple, poplar through it in the last month and works like a charm.

Quiet planing monster 03/12/2018 6:12:58 PM

Arrived a few days after I ordered. The trip down Eval Knieval's driveway (800 feet of a barely improved motocross trail) was hare-raising. My tractor (a Kubota 3901 with pallet forks) was just up to the task. Except for the weight, setup was simple. First board, reclaimed oak 2x4 from a 100 year old barn, came out perfectly flat and parallel. Gonna make a lot of beautiful pieces with this baby, that's for sure.

Seriously, I waited for months for Grizzly to get a cheaper model in stock. Eventually gave up and pulled the trigger on this. Is that the Bear's clever strategy?

The gearbox has a drain plug on the bottom and a fill plug on the side. When properly filled, the gearbox holds 16 ounces of 80-90W oil (I measured). ALWAYS remove the two cap screws at the top of the headpiece above the gearbox (see arrows in 2nd picture) when draining the gearbox. My gearbox actually had 24 oz of oil from the factory (probably filled from the cap screws), but when I drained the box without removing the cap screws, a vacuum lock prevented all of the oil from draining out. I only got 12 oz. out, then the box overflowed after adding a mere 4 oz of new oil. Fortunately Griz tech support told me about the cap screws (and sent the pic)--when I opened them, all of the old oil came out and I was able to refill with fresh, clean oil. BTW the cap screws are a much easier way of adding oil than the fill port on the side of the box.

After a month or so of pretty regular use I have to say this is a great machine--haven't had to make a single adjustment, zero snipe, super-smooth results.

I purchased this in December to upgrade from my 13" Dewalt and wow what an upgrade! It is quite and gives a good surface. My only complaint is that the fast feed speed is not much faster than the slow feed speed. I do get some snipe, but I think that's just because I need to adjust the outfeed roller a bit.

I love this planer. 06/01/2017 7:40:41 PM

I have owned this for about six months now. I'm very particular to having my machines setup perfect. I spent about 10 hours getting everything dialed in to within .002" when most of the tolerances Grizzly specifies are to .02". I definitely recommend getting a "Rotacator", it makes everything much easier. I have both beds perfectly flat along with the bed rollers, and did some playing with the height of the infeed/outfeed rollers, pressure bar, and chip breaker in their reference below the BDC of the planer head. I was able to achieve zero snipe across the board and even months later I rechecked and everything is still where I orginally set it. Some major tinkering up front will set you up for an awesome machine that cuts flawlessly leaving a glass finish, along with minal maintenance after the initial setup. I would definitely recommend this.

Love this big green monster!! 05/01/2017 6:18:48 AM

I have had this machine for about 6 months now and it is my new shop favorite!! I work with large live edge slabs and heavy rough sawn stock. This machine has saved me hours and hours of back breaking work. The adjustments are easy and accurate, the dust collection work very well, and the final pass finish is smooth as glass. As mentioned previously it comes very well packaged for shipping. My delivery was subbed out to SAIA and the crate had no damage at all, arrived in perfect condition. No kidding you need a forklift to get this thing from delivery point to where it will be set up. If you don't have one spend the extra cash for the rotocator, it will make set up worlds easier.

Grizzly service great, UPS Freight service POOR !! Machine was drop tested. 08/13/2016 12:04:55 AM

Just purchased this product and had it delivered via UPS Freight. I have not ran a piece of wood through it yet but wanted to give an initial review based on my shipping experience.
First: Grizzly customer service has been excellent thus far. They have gone out of their way to work with me through the issue below.
Second: UPS Freight can best be described as OK to poor at best.

Shipping fun. As you will find in countless YouTube reviews, UPS Freight will get it to you. The liftgate service was nice. The driver was professional and did his best to handle the equipment with care. Somewhere between where it left Grizzly warehouse and the arrival at my home is the problem. The shipping crate Grizzly shipped it in is well made. UPS somehow manage to put 3 forklift holes through the side of the box on three sides. Also it must have been dropped hard a few times because where the crate was affixed to the bottom was broken in several places to splinters. In addition, the crate was placed partially on a pallet but was hanging off it causing the machine to tip over once delivered.
Fortunately, after unboxing the machine it was relatively undamaged inside. THANK YOU Grizzly for wrapping the machine in heavy mil plastic to protect it from rain and the elements during shipping.

Will update this review once machine is setup and tested.

Top of the line machine!!! 09/24/2015 7:29:49 PM

Purchased 6 mos. ago. I use this machine everyday and it has saved me so much money and time it has already paid for itself. So smooth a finish I almost never use my drum sander anymore. I used to spend a fortune on sandpaper and the time for running it through my drum sander was slowing down my production time dramatically. This machine is heavy duty and I have never had a single problem with it. Love it!!!!
