Grizzly G0834 12" Parallelogram Jointer

The "heavy" in "heavy-duty."

With 84" of precision-ground cast-iron tables and a solid cast-iron stand, the G0834 12" Parallelogram Jointer weighs in at over half a ton!

A burly 5 HP, 230V, single-phase motor powers the 8-row spiral cutterhead with 96 German-made indexable carbide inserts. Carbide inserts hold their edge much longer than the high-speed steel of the straight knives and they are easily replaced or rotated should they become nicked.

The G0834 features precise parallelogram table adjustment with easy-to-reach handwheels. With the parallelogram table setup, you get more opportunity for fine adjustment of the infeed table and the outfeed table for perfect alignment.

The center-mounted, 47" L x 5-3/8" H fence assists with accurate edge-jointing. It has stops at 45°, 90° and 135° and comes with rack & pinion lateral adjustment.

Like all Grizzly jointers, the G0834 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 G0834 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.

AWESOME MACHINE!!! 12/09/2019 10:37:31 PM

Shopped and shopped and reviewed several machines. Kept coming back to this one and so glad I did. Upgraded from a 6" knife jointer to this BEAST!!!. I love the solid construction and the weight of the machine helps tremendously when jointing a long heavy oak board. Cuts effortlessly and smoothly. Very Nice machine indeed. Would highly recommend this one to serious wood workers. Well Worth the money.

What a nice machine! Easy to un-crate and put together. Clean-up was a breeze with WD-40. A good metal sealant and a coat of wax on the non-painted surfaces and I was ready to joint some wood. The 5 HP motor acted like it was working on a 4" piece of poplar - not an 11-1/2" piece of kiln dried oak. I ran some very nice bird's eye maple without a single tear-out. My "old" 8" jspiral ointer sold the day I listed it. What a nice upgrade for me. I highly recommend the one I bought - made in China! A special thanks to the Grizzly technician's advice on which machine to purchase.

worth the wait 04/11/2019 12:00:28 PM

Think I waited a year for this to come off backorder! Glad I did! Didn't give it 5 stars for a couple reasons. One is I havent used it long enough yet to really review it properly and secondly you must have a high volume dust collection hooked up or shavings end up in your way on the tables. Dust collection was on my "list" anyway so I've pulled the trigger on a clear vue cyclone. The jointer fence has easy to use adjustments and the 5hp motor with the spiral head go through hardwoods easily. Nice machine!

This was on back order for a long time, but was worth the wait! I would not hesitate to recommend this jointer.
