G1021X2 15" 3 HP Extreme Series Planer w/ Helical Cutterhead

Maximize the quality of finish straight from the planer.

The G1021X2 features a 15”, 4-row helical cutterhead complete with 52 indexable inserts that can each be rotated three times to expose new, sharp cutting edges.

The indexable carbide inserts are positioned along a helical pattern with the cutting edges at a slight angle to the workpiece for a shearing action that leaves a glassy smooth cut even on the toughest of woods.

The G1021X2 features a powerful 230-volt, 3 horsepower motor to power through cuts up to 3/32” deep at full width or 1/8” deep on material up to 6” wide.

Plane material from 3/16” to 6” thick with ease and choose between either 16 or 28 feet per minute feed rates for the perfect finish.

The precision-ground cast-iron table travels smoothly up and down on the heavy-duty 4-column supports and can be firmly locked in place for operation.

The G1021X2 offers additional features such as extra-large ball bearing return rollers, a large side-mounted handwheel, cabinet-style stand, pedestal-mounted control panel, magnetic switch with thermal overload protection and powder coated paint for years of protection.

Like all Grizzly planers, the G1021X2 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 G1021X2 manual was written by our U.S. based Technical Documentation Department and is packed with useful information. The complete and easy to read manual makes it easier to assemble and maintain your planer.

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.

Outstanding machine 08/11/2020 12:36:04 PM

I ordered a G0453Z at first when I received it it was damaged in freight The shaft where the crank handle attached to was bent technical support was a challenge with COVID and everything going on. My concern was that something More than just the shaft was off and after using it for a few weeks that was the case the next person that was given my case was GREAT to work with he recommended I send the the unit back for them to go threw I told him I could not be without a machine for that long mainly if this unit was not repairable it was on back order so that led to them sending me this machine the G1021X2 I arrived in perfect condition worked perfectly I did not know a machine could work so quite and efficiently highly recommend it and thanks to the technician that recommended the upgrade I received a 10 Percent discount I packaged the damaged unit back in the same crate ant shipped it back and received my credit within a day after it was received great costumer service THANK YOU COSTUMER SERVICE and great machine

Great Planer, but... 06/26/2020 3:17:39 AM

I have had this planer for a few weeks and really love it. It is a beast and eats wood. Has cut my milling time by half at least. BUT, the snipe is very bad. Worse than my Dewalt 735. I was expecting no to very little snipe, very disappointed about that.

Good Item 06/25/2020 12:06:16 PM

It would be helpful for the electrical plug to have the two hot leads be parallel with each other instead of 90 degrees to each other. Why is it that way anyway? The parallel plug configuration for the extension chord (which is necessary in most cases), yes, it's 10G wire, has to be made up and most of the female plugs have the parallel configuration.

Arrived with shipping damage but the people at grizzly responded quickly and sent new parts to repair broken roller assembly. The machine has so far worked great planing highly figured maple that was being butchered by my old three blade planer with newly sharpened blades. Another plus is how quiet it runs. Almost unbelievably quiet.for the noise issue alone I don't think the blade style machines should even be built anymore.

Great product! 05/30/2020 1:00:23 PM

Another excellent product from Grizzly. Took a bit of time to set up and remove shipping oil, but this was expected. One piece of advice when purchasing this planer, buy gear oil, way oil, and grease so your prepared for the routine maintenance. The unit ships with low gear oil level. DONT do an initial run without checking gear oil level. Awesome planer!

very satisifed 03/22/2020 1:18:16 PM

Far surpasses my old planer. Checked all adjustments all were in tolerance as it came from factory.
Planed popular and walnut so far with great results.
Machine runs smooth, no vibration, and surprising quieter than i expected.
Definitely built for many years of good service.
As i shopped all choices of planers i am now convinced i got the best machine for a fair price.
Even has a great paint job.

Happy with purchase 03/16/2020 11:52:20 AM

I purchased this planer May of 2019. Almost a year ago. I've held off on the review because I wanted to use it for a while and get to know it. If you're thinking of getting this you already know the advantages of the helical cutterhead. They're all pretty much true but don't throw away your card scraper and sand paper. It's a big improvement on surface but you will still get tear out on tricky grain. It's much reduced but still will happen. If you take too deep a cut you will see some tracking on the surface. Like any tool there is a learning curve with this one. When you first get this do all the things the manual says to do. In addition to that open the top of the machine and check the chip deflector. Mine came set for use without a dust collector attached. Making the adjustment for a dust collector improved chip collection dramatically. That and taking shallower cuts. It's a wonderful addition to my shop and a good value for the price. Why the four star rating? Because of the following admittedly picky things: Changing the oil on this is a major pain in the ass. The infeed roller is serrated and will leave tracks when taking light passes on softer woods. I adjusted the tension on mine but still have to be carful. There should be a depth stop on the machine that you can preset so you don't go beyond a desired thickness. My old lunch box style planer had one. It was a very simple arrangement and easy to use. The thickness indicator on the Grizzly is in a very inconvenient place to read. Keep a ruler handy when planning. In the manual it says to use the faster feed speed to put a final finish on a board. To me this is counter intuitive. When running a board on my jointer it seems that taking a SLOW light pass will result in a smoother finish with less tear out so why not the same for the planer. I have a Grizzly jointer with a helical head. So I think there could be some improvements on this machine but overall I really like it.

Amazing machine! 02/21/2020 12:26:02 AM

I dont usually take the time to write product reviews but, WOW, what a wonderful piece of equipment for my wood shop! My only regret is that I should have purchased a spiral machine years ago. The G1021X2 produces an amazingly finish. It was easy to setup and I was planing in about an hour and a half after delivery. If you are on the fence about making this purchase, I strongly recommend going for it, you will not be disappointed!

Best tool in my shop 02/06/2020 3:13:17 AM

This replaces my dewalt straight blade planer and it is phenomenal how smooth a finish it produces.

So far so good 02/02/2020 2:31:11 PM

I have had this for a little over a month and so far I'm very happy with it. The overall fit and finish is surprising for such a reasonably priced machine. Other comparable units are easily twice as expensive.

Great Planer , pleased with it early on 01/13/2020 2:41:58 AM

Unit arrived in excellent condition, crate condition and planer as well . Very well packaged, Basically assembled already . A little disappointed in the lack of better instructions as to the best methodology to add gearbox oil, but a quick call to the technical service folks and we were all good. This replaces a 15+ year old Dewalt 12 1/2", 2 knife, so a definite step up. The noise level is greatly reduced with this machine ! I had buyers remorse after I ordered it, but that disappeared upon arrival, which was only 5 days after ordering ! Shippers had great tracking emails. All specs were checked after assembly and we're spot on ! Looking forward to many years with this planer

Excellent Planer! 12/30/2019 2:57:29 PM

I bought this to replace a Delta 13" floor model planer with straight knives, and am so glad I did. I do a lot of work with curly maple, birdseye, figured cherry and the like, and was tired of all the torn grain, and having to plane wood 1/8" over and drum sand it to thickness. It's not impossible to get tearout with this planer, but you really have to work at it to do so. As long as you are cognizant of the grain direction and feed it with the grain tipped up towards the upper back surface (same principle as with any jointer, but reversed..), you will get a literally glassy smooth surface on figured wood. The first few curly boards I ran through it I had such a GIANT smile on my face. The fact this planer makes half the noise of the old one is a bonus, but I wear muffs due to the dust collector anyways. It arrived on time, very well packed and crated, and I was able to move it from the street into my shop with only a pallet jack. I've heard other comments about the liberal amounts of grease all over bare metal, but it only took me 20-30 minutes with some paper towels and SimpleGreen to get it all cleaned up, then a coat of paste wax on the beds. The fit and finish on this is excellent, and I put it on it's new Grizzly mobile base by myself by following the instructions for assembling the base around the planer while it was on the floor, total cake. The adjustments for the rollers and such were spot on, and it makes a nice, parallel cut right out of the gate. This machine is SO worth it I can't tell you, you won't be disappointed, and I saved many hundreds over 2 competing planers.

Excellent Planer 12/26/2019 4:27:25 PM

Purchased this planer in early Nov. Replaced a Dewalt 735 with Bryd Shelix head that I've used for the past 4 years.

I Finally got a chance to send some lumber through it this past week and very impressed with quality of finish. Machine has plenty of power to cut right through hard maple and rustic hickory. Noise level is a fraction of what the Dewalt was. The spiral cutting head may even work better than the "Bryd Shelix" as there is little if any tear out on the knotty rustic hickory. Super impressed with this. Finished cut has some fine lines that easily sand out. Overall I am very pleased with this machine.

Works as designed 12/06/2019 2:06:43 AM

Used it briefly so far. Quieter than the other manufacturer machine I had due to helical head. Helical head allows approximately 98 percent shaving pickup compared to 75-80 with the conventional head. Comes out with appearance of very lit sanding needed and no blades marks. Just buy gear oil when you purchase the machine . I have no regrets with this machine.

great finish, a real beast 11/30/2019 9:23:20 PM

Bought this as an upgrade over a DeWalt 735 that was going to take forever to plane a few hundred board feet of lumber. The 1021x2 makes short work of it and leaves a much-improved finish. Set up was pretty simple, I drained and replaced the oil as everyone recommends, assembling the extensions was a little finicky (tightening throws off the leveling), all-in-all was pretty straightforward.

Anonymous Reviewer
Worth far more than the price. 11/29/2019 11:27:29 AM

Im right in the midst of my first job with this planer. First reaction is that its incredibly quiet. Secondly, I find myself second guessing whether the maple I bought was hard maple or soft. This planer moves effortlessly through a 1/32 inch cut on a 14 wide panel. And yes, its hard maple. Most pleasing of all is the quality of finish even on curly grain. The shop where I used to work ran a 42 double headed overhead sander. With this planer I dont miss the overhead sander at all.

slick as a whistle 10/28/2019 5:30:59 PM

I have been shopping for a planer for some time. I have other Grizzly equipment. I chose the G1021x2 15" Helical. One it was made in Taiwan and not China. Two, it was an upgrade from the 1989 version I had that had the roller infeed and out feed tables, Three, the reviews all mentioned the quietness of the machine. So about 10 days ago it was delivered. I knew about the oil. So I inquired about the ISO 320 gear oil locally. No one I talked to seemed to know the equivalent. So I went to Grizzly and ordered the 1 gal ISO 320. I also had read not to mix the gear oils so I drained the existing oil that was in the case, probably about 1/2 of what was required. I bought a pump to screw into the gallon container and filled the gear case with the proper oil. I also ordered a rotacator and a torque wrench that would do inch/lbs to insure all inserts were at 55 inch/lbs. All the adjustments required seemed daunting, but with the Rotacator it was quite fun and I became very familiar with the planer. Dialed it in to specs and it planes very well. I have not run much thru yet, but test pieces for tool marks, snipe were minimal and side to side taper was perfect. Very Pleased with the product. Looking forward to some great times with my son woodworking, because I am outfitting his shop one day. An update, I began to run some walnut thru and noticed a taper. I was disappointed. I got out the rotacator and went thru every thing again. I had a couple of discrepancies, made adjustments and now is spot on. I don't see how anyone could set up a planer with out the rotacator. Worth the money. Also in the process of adjusting and readjusting you get more familiar and are less afraid of making any adjustments. You will love this machine

Arrived in good shape. Easy setup, maybe two hours, including assembling the mobile base. I upgraded from a bench top planer with a shelix head. The difference is incredible. More power, less noise, better quality of cut. Should have upgraded years ago.

Especially nice on thin stock. 07/25/2019 8:41:39 PM

The helical cutter head is bona fide leap forward for wood planing. Depending on the wood, it yields a very smooth surface that saves time.

Looks great!! 06/27/2019 5:49:38 AM

I ordered the 453 with spiral cutter head originally, was back ordered twice so I bought this one. I love the way it looks! Unfortunately thats all I know at this time! The Grizzly web site recommends the 620 twist plug and receptacle. However this machine comes with a cheep imitation! The big box stores dont carry the receptacle to match the plug! So I have to wait some more! Ill order it from Grizzly, (if they carry it). Hopefully they can just send it to me, the planer left Grizzly, went to one trucking company who in turn sent it to another trucking company, two weeks after leaving Grizzly I finally received it! The crate it came in was damaged pretty good, but it was boxed very good, and no damage!! Grizzly did that very well!! It is a beautiful machine, and I cant wait to use it! Lets work out the bugs Grizzly,

Delivered low on gear oil 06/09/2019 4:39:49 PM

I love the machine but I was irritated because it was delivered very low on gear oil. When they fill it at the factory they are not giving it enough time for all the air to come to the surface. The factory needs to top off the machines before they leave or ship the machine with an extra pint of gear oil.

G1021X2 15" 3 HP Extreme Series Planer w/ Spiral Cutterhead 06/09/2019 4:02:22 PM

I have waited for this planer for a while now, It came to my house well packed and in perfect shape. All the setting were dead on out of the crate. Small amount of assembly and cleaning the packing grease off but after checking it over and adding gear oil to the machine it was ready to work. My only complaint is that they did not send gear oil with it.

Product was delivered in perfect conditions. If you don't have a forklift (Most homes don't), it does require 4-guys to move off shipping crate. It does have bars to grip. We used these to support 2x4's which provided an easy means of 4-guys lifting the unit. Assembly was straight forward. Take extra time to ensure the in-feed & Out-feed tables are level. Had a 220 line installed, and turned it on...Everything worked perfectly. This is definitely a planer designed for a production environment. Finished pieces are ready for finish sanding...no need for 80 Grit sanding to remove knife marks. Noise level was much lower than expected. Highly recommended for a serious woodworker.

This baby is a money maker! 03/26/2019 9:51:21 PM

12 Year user of this machine in professional furniture/cabinet shop. Just completed a rebuild of the gearbox, as things started leaking (slightly) a while ago. Not surprisingly, the two smallest gears transferring power from cutter head to gear drive for feed rollers had pretty extreme wear. However, Pleasantly surprised parts are readily available from Grizzly and very reasonably priced. Debated replacing vs repairing. In hindsight, I may simply replace in the future, but truth is mine's good to go another dozen years. This is an outrageous value, considering the dollar figures it's generated over the years. If considering this machine:
1> Do not waste one dollar on a machine without the spiral carbide head. I've rotated mine to 4th fresh edge now, with another year or two before full replacement needed. Just a month ago, I broke my first and only carbide chip in 12 years. A particularly nasty knot in pine, angled perfectly to jam into cutter head. Machine never hesitated, but I realized what happened by the straight line I was then seeing on the face of finished boards, left by an exploded carbide chip.
2> In lite of the gear wear, I'd say spring for a high dollar full synthetic gear oil in hopes of a longer run. Also advising more frequent oil changes, like every time you rotate the carbide. My 2 changes in 12 years didn't stave off the wear, but then there's a LOT of torque on those little guys. To my surprise, none of the bearings seemed bad, though they got swapped out too. Once this thing's open, you want to make the effort worth it. Again, pretty reasonable at $4-$12 per bearing. Also, if you're about to do the same, grab gear #112 (P1021112) and #117 (P1021117). Was down 5 days waiting for parts - had someone told me, I'd have ordered both prior to opening the rebuild project. Less than $20 for the pair(!)
3> As for the leakage, wish I could say precisely where it came from. Check your gear box cover for torque - mine were pretty easy to loosen, leading me to believe tightening would have reduced dampness around the housing. Just occasionally had a "spit" of oil on the first board after it sat for a few days. Main cutter head seal didn't seem bad, nor is it fully bathed in the gear oil. Perhaps too much 30 weight applied to feed roller shafts was migrating through internal dust chip build up(?) Either way, think I got it whipped now...

Conclusion: If you're a relatively small shop like me and shopping for a reliable, accurate, clean/mean running planer, stop looking and just buy this baby. It's a money maker!
(don't get me started on how much I loooove my 10" Grizzly jointer - a killer team for flattening and surfacing rough lumber!)

Thank you, Grizzly, for providing great machines and service to get my business going, and now keeping things running!

Love it 01/18/2019 12:58:48 AM

Arrived in great shape, well packaged, and with a little assembly, ready to plane. I haven't needed to adjust the factory settings (yet), and I have experienced very little snipe, levelness across the board, no roller marks, and as many have commented, very quiet (especially when compared to my Delta 13" bench top planer).

11/05/2018 11:28:24 PM

Initial impressions: For the price point, unit is well made and well adjusted. Extension tables are reasonably flat by my simple check against straight edge, and set up was straight-forward. So far, have run trials with pine, doug fir, birch, and oak. Finish of cut is excellent, cutting is smooth and quiet. Board thickness across width varies just a bit, about 0.005" across a 6" wide board. I probably will not mess with trying to adjust that out unless it becomes an issue. The thickness adjusting mechanism is a bit tight, but I expect it will mellow out with use. So far, unit seems very good, but I've not had any other surface planers to compare against. Spiral cutterhead is sweet!

Great planer. 09/03/2018 2:14:47 PM

First introduced in 2009 , I've had mine now for 9 years. Replacement inserts quite expensive but considering there longevity well worth it . I have only rotated them once . You will have scalloped milling marks , like all of these type of heads produce , but tear out is all but eliminated. I work with all hardwood, primarily hard maple and cherry , that have a lot of switchback grain , and this planer does a great job . It has stayed in calibration too.
