Description

We see a future built on great brands, products, and people. In every facet of our business, we leverage the strengths of our global infrastructure to maximize the benefits of all three. Combining a jointer and a planer into one machine, Jet's 12-inch JJP-12HH adds a helical cutterhead with indexable carbide inserts for a superior finish and quieter cut. Because it has no protruding knives, the helical cutterhead minimizes the clutter of chips flinging out from the machine--and it also greatly reduces tearout. It requires no tuning of individual knives since the cutterhead is fixed. Additionally, the innovative parallelogram design keeps the table close to the cutterhead, allowing for precise depth-of-cut adjustments. Jointer/planer combination machine with helical cutterhead with indexable carbide inserts (view larger; also see schematic image with key features). Built-in dust chute with 4-inch dust port (view larger). Versatile Combination Saves Space and TimeWhether building a backyard deck or a commercial structure, the Jet JJP-12HH 12-inch planer/jointer provides all-in- one precision-cut capability to help get your job done quicker. This machine makes a no-tool switch from jointer to planer in just a few quick motions, allowing you the capabilities of both machines without compromising your work space.Both functions offer a full 12-inch width capacity and 55-inch tables, so no extra ripping process is needed when you switch between modes. And, in addition to its compact bench-top design, a rugged steel stand is included for those times floor positioning is more convenient.Easy-Handling Adjustments for Maximum AccuracyThe Jet JJP-12HH's oversized hand wheel and knobs fit comfortably in your hand, allowing for extremely fine-tuned adjustments. The wide-spaced handles make it easy to stabilize stock to the heavy-duty, 43-inch-by-6-inch fence. Particularly handy for complex projects, the fence stays in place between function changes and sets easily for bevel cuts up to 45 degrees.Expert Materials Offer Enhanced OperationThe Jet JJP-12HH runs on a heavy-duty 3-horsepower, 12.5-amp motor, supplying the power you need for a variety of cutting applications. Its table top is precision-flattened to ensure a smooth, even cut. The tough, cast-iron infeed and outfeed tables adjust individually to give the work piece superior support. Cutting is performed by the helical cutterhead with 56 inserts.The JJP-12HH also includes a premium dust collection shroud, which rotates in both settings and has a standard four-inch outlet port, allowing for efficient dust collection that cuts your clean-up time to a minimum.Top-Notch Features for Safe, Consistent WoodworkingDuring jointer operation, the bridge-style cutter guard's base- located adjustment knob allows wood to pass evenly beneath the guard, preventing you from pushing down directly over the cutter. The planer function's cutter head prevents kickback with gravity-operated fingers, while its metal infeed roller and rubber-coated outfeed roller maintain a consistent non-marring feed rate. For both operation modes, the JJP-12HH features self- engaging locks that fall into place when you make the switch between functions for optimal security. For additional safety, the magnetic on/off switch has a built-in limiter to prevent start-up after power outages and while you switch between modes.The JJP-12HH is backed by a five-year warranty.What's in the BoxOne Jet JJP-12HH 12-inch jointer planer.SpecificationsMotor: 3 horsepower, 1 phase, 12.5 amp, 230 volt Jointer table size: 55 inches by 12 inches; 33-1/2 inches tall from floor Fence size: 43 inches by 6 inches Fence tilt: 90 to 45 degrees Planer table size: 21-1/4 inches by 12 inches Maximum cutting thickness: 8-3/4 inches Overall dimensions: 55 inches by 29-1/2 inches by 39-2/5 inches Stand footprint: 22 inches by 19-1/2 inches Warranty: 5 years, limited P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); From the Manufacturer The innovative JET JJP-12HH Helical Head 12-Inch jointer/planer takes our award-winning jointer/planer combination machine and makes it an ever better investment.

  • Got What I Paid For
Style: Planer/Jointer with Helical Cutterhead
My Jet Jointer / Planer (Jet) arrived 10 days after placing the order. The shipping coordinator indicated the palletized, plywood crate would be unloaded at the street - 50 yds from my garage. Since I had no way to move it to the garage, I warned her I may refuse delivery. She said OK. The driver of the tractor-trailer used his pallet jack to unload and pull the unit into my garage. He placed it exactly where I wanted the machine to reside. He got a nice tip... So far, so good. The Jet was contained in a 1/2" plywood box resting on chip board pallet blocks. There was no apparent damage to the container. I disassembled the box and inspected the Jet. No apparent damage to it, either. I began following the instructions for assembling and adjusting the machine. The jointer beds were co-planer but the fence did not adjust to a precise 90 degrees. It was easy to adjust. The adjusting levers for locking the angle of the fence are clumsy. I swapped them for the locking knobs that secure the horizontal location of the fence sled. This swap seems to be the logical set-up. The fence and sled are now quite easy and precise to move and adjust. It is fortunate they shared common threads. Next, I checked out the cutter head drive belt and the associated feed roller drive belt. The feed roller belt, when disengaged, is slack and does not rotate. When engaged it tightens up and slides across an "idler rod". Thats OK except this "idler rod" is a 1/4-20 threaded bolt! Why Jet would allow a drive belt to slide across threads under tension I do not understand. In any case, I replaced this bolt with a "1/4-20 x 70 mm Coarse Antique-Brass Steel Hex-Drive Connecting Bolt (4-Pack)" that I bought at Home Depot. It has a smooth shoulder for the belt to slide on. Everything else seemed to be OK and set-up accurately. California electrical code now requires all 220v circuits to be composed of 4 wires. This allows the machine or appliance to be able to support 110v auxiliary functions such as a work light or digital depth gauge in my case. I decided to run 12/4 SOOW stranded, flexible cable with a NEMA L14-20 locking plug and matching receptical. The Jet comes with a 12/3 cable with no plug. Where Jet's cable exits the machine enclosure, I installed a junction box screwing into the existing machine cover plate threaded holes. I cut off the extra Jet cable to make the splice. The machine fired right up turning in the correct rotation and ran quietly (relatively) with no appreciable vibration. I don't understand why Jet indicates the machine should be plugged into a 30 amp circuit when the machine comes with 20 amp cable... The final challenge was to get the Jet off the pallet and onto the Jet Heavy Duty Mobile Base. Working alone, I needed some method to hoist the 500# machine, remove the pallet, install the mobile base and lower the machine. After conjuring up countless alternative scenarios, I noticed the Rockler steel frame, clamp rack I had recently acquired. It turned out its dimensions and steel construction were perfect to support my ratchet straps (used to secure plywood / lumber to my roof rack). I was able to easily get the Jet up and down into the mobile base. Overall, my areas of irritation were, for example: the decorative red and black color band at the bottom of the enclosure had bubbles and was coming un-adhered in various places; welds on the dust shroud were coarsely ground down then painted leaving a poor quality perception though perfectly functional result; the edges of the cast iron beds were also coarsely ground plus some corners were left very sharp requiring some hand work on my part; the beds themselves are ribbed in a way that suggests the finish is intended to reduce sliding friction but result in the spaces between the high points being rough and grabby - don't use paper towels - they shred and the resulting lint is hard to remove. Areas of satisfaction are: the helical cutter head delivers a very smooth surface; sliding material across the ribbed bed is easy; the planners' drive rollers grab material smoothly and securely and so far no snipe! The vertical adjusting mechanism runs smoothly with no squeaking or rubbing; the fence now adjusts easily and accurately. Its beefiness seems appropriate for its purpose. The 4" dia. dust extraction ports connect to my house hose with a good seal but is easy to disconnect. I can keep the connection intact when changing over from jointing to planning by simply rotating the hose with the extraction hood (a nice surprise); and the dust extraction in both modes is very high - at least 95%. A real benefit. I became an immediate fan of being able to lift both the in-feed and out-feed beds of the jointer at the same time, rather than individually, as is the case on a number of competitors models. The mobile base adjusted easily and fit the machine base with about a 1/4" gap all around; with the casters locked, the machine is very stable with no shifting or wobble during operation. Moving the machine in the base is very easy. In closing, I got what I paid for: a robustly made machine with a fine helical cutter head that performs all its required functions well. What it lacks is: design engineering sophistication and high quality fit and finish. I knew what to buy to obtain those attributes but was not prepared to pay the additional ~$1500. Given the quality of the jointing and planing I have obtained so far, I believe this machine will perform very well supporting my cabinet making hobby. I have attached a few photos to illustrate some of the issues discussed. ... show more

  • Sad about Jets quality decline
Style: Planer/Jointer with Helical Cutterhead
First off, this review is probably going to echo most of what's been said. Quality - It's pretty bad. Like what was previously stated, the table finish is likely some cost reduced surface. Not nearly as nice as a traditional polished cast surface. Can't wipe it off with a paper towel, it will shred it. In addition the poor material my tables had dents, dings and spirals from mis-handling and what appears to be a slipped driver. Awful. The bracket that holds the extruded aluminum fence on is just a chunk of stamped steel. As another user said, as you extend the fence over the range of the bed, this stamping deflects and throws your fence out of square. The engineers at Jet should be ashamed of themselves, except the fact they probably had some manager breathing down their necks to bring the cost down. Generally the fit and finish is bad. My dust collection hood had some extra brazing? material inside and it looks like there is a metal bird nest inside. Not ideal for flowing chips. The anti-kickback teeth came with all kinds of chips and rough surfaces on them. Just bad quality control. Total garbage. The only quality part on this thing seems to be the cutter head. That thing is beautiful, and ironically not made my JET. Jets quality has plummeted over the last 20 years.I love my jet table saw, and my lathe, but this unit is changing my attitudes quickly. Calibration - The calibration of this machine is a horrible process meant only for a masochist. Nothing wants to stay in place and everything is dependent on something else. To adjust the tables alone requires adjusting TWENTY fasteners. 4 to level each hinge, 3 on each hinge for the hold down, 2 at each front edge, and 1 on each table for the hold down. It's a terrible litany of adjustment and re-adjustment of opening and closing the machine. The manual said "its adjusted from the factory, but that is a bold faced lie. Also on my machine, the tables can be adjusted so that it can touch the cutterhead. It makes me paranoid every time I make an adjustment, so I wheel it around through the range of tables to ensure i'm not going to be cutting the bed. My planer bed came adjusted luckily. So we've come to the only redeeming part of this unit, the performance. After about 10 hours of trying to dial the machine in iIve had the opportunity to run some lumber through it. The Planer is a dream, the jointer works well, but i still have a tiny taper I can't seem to get rid of. I hope the machine stays dialed in. I would say this unit is barely worth it based on the poor quality and effort put into calibrating it. If I had to do it over, I would spend more time investigating other brands. ... show more

  • Excellant machine, one minor flaw
Style: Planer/Jointer with Helical Cutterhead
I've had this machine for six months or so. Recently I jointed and planed a 6 foot long 2X10 of rough cypress with it. To be honest I was astonished at how well it performed. The work piece was quite heavy, however there was no tearout or snipe in either process. There is a question about the table above, it is dead flat and slightly ribbed iron. I find that (particularly with the cypress) you need to wax the table and keep it clean to make the material slide well. The one con I've found it that the fence, while flat and straight, can be difficult to set to 90 degrees and have it stay there as you shift the machine back and forth between jointing and planing. The adjustment mechanism on the jointer is just cheap, and a bit frustrating to use. As others have said, this is not a machine to uncrate and start using. You have to get the right circuit run, you need to clean up the tables, and in my case one of the belts had come off the pully during shipping. I cleaned the maching with CMT Orange bit and blade cleaner. It seemed to work well, and has little odor. Follow up with a coat of wax or dry lubricant. Switching from one function to the other is quick and simple, particularly when just flattening and thickness planing. It can be tricky to edge joint, and I've not tried to do anything but a 90 degree edge joint so I'm not sure of that. I do love this machine. ... show more
