The JET JJ-6CSDX (#708457DXK) & JJ-6HHDX (#708466DXK) 6” Jointers are identical in design and construction with the major exception being the cutterheads. The JJ-6CSDX comes with a three-knife cutterhead, while the JJ-6HHDX is equipped with a helical cutterhead with 27 carbide inserts.

The JJ-6HHDX comes with an all steel enclosed base cabinet. An integral tab at each end of the cabinet bottom makes securing the jointer to the floor easy when a suitable surface is available. This cabinet provides a stable platform and puts the table surface at a comfortable 31-1/4” above the floor.

The base cabinet also houses the 1hp, 1 phase 115/230V TEFC (totally enclosed fan cooled) motors (pre-wired 115V) and wiring to help isolate those components from the dust-prone jointer environment. A large door on the rear of the base cabinet provides easy access to the motor should that be needed in the future. The 1hp motor spins the JET JJ-6HHDX cutterhead at a very consistent 6,000 RPM for a good balance between speedy material removal and a silky-smooth surface on the wood.

Also in the base cabinet is the dust chute that runs from under the cutterhead down to the cabinet side. A 4”-diameter port makes attaching your dust collector easy and adapter free. The angle of the dust chute makes it very efficient at evacuating the debris from beneath the cutterhead. The JET JJ-6HHDX has a paddle-style switch mounted on a stalk that places it behind and above the fence.

The JET JJ-6HHDX Jointer features a long, cast iron table with a smooth, flat precision-machined finish that keeps the wood sliding predictably while ensuring accuracy. At 55-3/4 x 7-3/8” this table makes straightening large project pieces accurate and reliable. The overall cut capacity of 6 1/16”-wide by 1/2”-deep provides plenty of capacity for the most active of home wood shops. The outfeed table even has built-in ½” rabbeting ledges that add a little more versatility to the JJ-6HHDX.

Both the infeed and outfeed tables feature exclusive front-mounted handwheels that make table height changes easy and accurate. The infeed table has a full ½” range of motion and features an easy-to-read scale that makes setting the exact cut depth you want simple. An automatic limiter on the JJ-6HHDX prevents accidentally taking overly aggressive cuts more than 1/8” deep. The depth limiter can be manually overridden easily, but it requires the operator to intentionally release it.

The JET JJ-6HHDX jointer comes equipped with our true helical cutterhead. This high precision cutterhead has 27, 4- sided carbide inserts mounted on individual seats. This system requires no adjustment of the cutters. Each insert has precisely machined angles in its top and all four cutting edges. When combined with the equally precise mounting pads on the cutterhead these angles produce an ultra smooth slicing action that creates a highly refined surface on the wood.

The inserts are made of high-quality carbide that holds an edge for a very long time. Combined with the true, lowimpact slicing action, the cutters stay sharp for a very long time. Should an edge eventually go dull, you simply index the cutters to another of the four identical cutting edges and go back to work.

Another nice feature of the helical cutterhead is that should a hidden piece of metal get onto the JJ-6HHDX, only the inserts directly in line with the metal will need attention. Those few cutters can be indexed or replaced, whichever is necessary, minimizing cost and downtime. We even include five extra carbide inserts, mounting screws and a pair of wrenches to handle the replacement!

This jointer comes with a versatile 32 5/8”-long by 3-7/8”-tall cast iron fence system that tilts to 45-degrees in and out to handle all of your bevel needs. Changing fence bevel angle or position on the table is tool free. All fence controls are located near the center to keep them in easy reach of the operator.

Fully adjustable stops are provided at 90° and both 45° settings. The 90° stop features a flip-out bar that provides instant access to the 45° bevel capability away from the operator. It also makes returning to the 90° setting just as quick. The fence has a composite insert on the bottom edge that lets it slide smoothly across the table surface for easy adjustments. This insert also prevents the fence from scratching the table surface.
