Grizzly G9860 The Ultimate 12" Jointer

It’s named “The Ultimate” for a reason.

If you're looking to spend a little more on a high-end jointer, you'll certainly get your money's worth with the G9860 Ultimate 12" Jointer. This professional jointer is loaded with industrial features, such as parallelogram table adjustment, twin V-belt drive and a heavy-duty cast-iron base with noise dampening system.

For the ultimate in precise table height adjustments, the close tolerance, precision-ground cast-iron infeed and outfeed tables are effortless adjusted through the handwheel controls. This machine's massive weight of nearly 1200 lbs. of solid cast-iron construction guarantees stable operation and a lifetime of satisfaction. And remember, a jointer this size can save additional time and money by transforming unusable "cupped" lumber into perfectly flat stock.

Like all Grizzly jointers, the G9860 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 G9860 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 jointer are available on-line and shipped from the Grizzly parts warehouse in Springfield, MO.

Truly the Ultimate Jointer! 05/01/2020 1:14:23 AM

It's like a small aircraft carrier, this jointer is HUGE!! The hardest part of setting this up was getting it off of the shipping pallet. I used a hydraulic car jack and stacks of 4 x 4's and took my time as I did this without any help. Make sure you buy SJOOW cord for the power cord as what comes with it isn't very long. The packaging was great and saved it from damage as the freight company tried their best to test the durability of the container (but didn't succeed). The settings from the factory were dead on and the directions are very detailed and easy to follow. When powered up it doesn't shake or shimmy, you can stand a nickle on edge on either table while it runs and it won't move. Definitely worth the investment.
Thank you Grizzly!

Definitely the ultimate 12" jointer 12/08/2019 3:18:28 AM

I recently purchased the G9860 jointer and I am extremely satisfied with every aspect of the machine as well as the purchase. To begin with, Grizzly Tools have perfected the online purchase experience; from the quality of their website, the in-depth information available, through the telephone ordering, and to the delivery, everything was professional, efficient, and well done. Being a Canadian customer, I was nervous about potential charges and problems related to importing expensive machinery; there were none - no customs fees or hassles shipping to Canada.

As for the machine itself, I feel Grizzly is correct when they claim that it is the best 12" jointer on the market today. Of course it leaves silky smooth finish on all of the surfaces I've jointed so far, why wouldn't it? This is the identical jointer once sold by now defunct General International, and its a beautifully built machine. The 3hp motor has plenty of guts for the job, the beds are polished and dead flat, the crank is effortless; everything about it is good. I particularly like the low stance of this machine. It presents the operator with a large wide low surface to flatten and straighten small and large boards alike.

What motivated me to cough up the additional dollars to purchase this machine rather than one of the several other excellent 12" jointers on the market, was its narrow dimensions. This jointer is the narrowest 12" jointer out there; and in my shop, where every 1/16 of an inch counts, I was able to fit a 12" machine in the space my 8" jointer previously occupied. The G9860 is 32" wide (not including the crank handle knobs), yep, that's 2" less than the 34" shown in the specs. This is because it doesn't have a rabbitting shelf, or a rack and pinion tubular fence adjustment mechanism.

The set-up was simple, and cleaning the surface protector was easy. I had one issue with an otherwise perfect machine, and that was the return spring on the guard is way too strong. No matter how well I tried to position the guards spring cylinder, it slipped, and the guard slammed with a bang against the fence on its way back. To remedy this problem, I carefully drilled and tapped and added another grub screw on the opposite side of the spring cylinder, before removing the original grub screw that tensions the guard. This released the tension on the return spring by one half rotation, enabling the guard to return at a slower speed with much less force. It works great now.

I would highly recommend this product to any purchaser whether, hobbyist or professional.

More than I expected 01/16/2018 7:18:29 PM

I received my Joiner several weeks ago but just today got the shop wired to get it running. I live in a residential neighborhood but was able to get the massive crate off of the liftgate with a electric hydraulic pallet left. I placed it on a cart and wielded up my driveway and into the garage without incident. After uncrating everything was perfect. The oil preservative was easy to wipe off with a large bath towel. I didn't use any solvents just wiped it and buffed it. Since I just moved in to my residence it took me awhile several weeks before I was able to get it wired up. It's the smoothest machine I've owned to date. Very quiet and zero vibration. I didn't take much time to set the outfeed table, but despite that I got perfect glass Smooth Cuts. I jointed some pieces of oak and walnut and couldn't be happier. It may be a while before I can give it a really good workout as my dust collection system is on the floor and not yet installed. But so far I am really delighted with this purchase. My only negative comment would be with customer service. For some reason the gentleman that answers the phone every time I call is probably the worst person I've ever spoke with on a customer service line. In fact I talk to him before my purchase and almost bought another brand because of his inability to answer questions and his inability to be helpful. Every issue I called him about I had to resolve on my own. I'm not trying to be nitpicky but if I owned a business and I didn't want to be bothered with people calling customer service, then this is the guy that I would have answering the phone. In short order no one would call with questions.1-15-18 Update...I have contacted customer service a few time since my original purchase and have talked with other agents and they were all top notch!!! Machine is excellent!
