JET JJP-12 Jointer-Planer
A frustrating choice
woodworkers often face
is whether to get a jointer
or a planer first. That
choice is made more
difficult because these
machines compliment
each other to dimension,
square and smooth the
wood. The new JET JJP12 Jointer-Planer
eliminates that problem
and brings both
capabilities to your shop
The JET JJP-12 Jointer-Planer brings two crucial woodworking processes,
jointing (left) and planing (right) to the shop in one space and money saving
package.
in one accurate, durable and economical package.
The JET JJP-12 Jointer-Planer is based on a heavy-duty, fully welded steel base cabinet
that houses the motor along with the planer table mechanism. The cabinet also provides
solid mounting for the associated controls as well as supporting the jointer table and
fence assemblies.
Power
The JET JJP-12 Jointer-Planer features a 3HP, 230V,
12.5A, 1Ph TEFC (totally enclosed fan cooled) motor
that supplies consistent power to the cutterhead that is
used for both jointing and planing operations as well as
the feed roller system in the planer mode. The belts and
feed roller drive chain systems are contained within the
cabinet but readily accessible through the large

removable panel on the cabinet rear.
To protect the motor – and you – we include a
magnetic On/Off switch with a built-in limiter. This
switch prevents excessive variances in the electrical power from damaging the motor.
Another benefit of a magnetic switch is that should the power go out and then come back
on the JET JJP-12 Jointer-Planer will not restart on its own. The On button must be
pushed after power is restored to start the machine. The limit switch also prevents
machine startup while changing modes of operation.
Capacities
To make the JET JJP-12 Jointer-Planer as capable as it is versatile, the jointing and
planing width capacity is a full 12”. That capacity allows you to work with wider boards
without having to rip them down to fit common jointer
widths in the 6 to 8” range. Because both the jointer and
planer width capacities are the same, you can move
between those modes without having to add an additional
ripping step to the process.
3-Knife Cutterhead
The JET JJP-12 Jointer-Planer uses a large 2 ¾”-diameter
cutterhead fitted with three high quality knives for both
jointing and planing operations. The cutterhead turns at
5500 RPM for all operations. The knives are retained
with conventional wedge bars and have jacking screws
that make setting their height precisely much easier.
The precision machined 3-knife cutter
head and feed roller system (planing
mode) make the JET JJP-12 effective.
Because this cutterhead is used for both jointing and
planing, setting the knives one time is all that is required.
Changing Modes
From the beginning, along with accuracy, capacity and
durability, developing a fast, easy way to change
between jointing and planing modes was high on the
design criteria list. The JET JJP-12 Jointer-Planer
sports a very simple, tool-free hinge based system that
allows changing between jointing and planing modes
very quickly without having to remove any
components.
A pair of locking levers on the cabinet sides release the
Changing from jointing to planing or
back on the JET JJP-12 is fast and
simple. Unlock the jointing deck, lift it to
its upright position, flip the dust collector
into planing position and engage the feed
rollers. It takes less time to do than to
describe! Going back to jointing is just as
fast.
jointing bed which is then rotated up to expose the
planer section. Lifting the cast iron jointer bed
assembly (moves as one piece) is made easier because
of spring-assisted hinges that reduce that effort
substantially. A drop in lock at the hinge point secures
the jointer bed in the upright position.
The dust collection shroud with its 4”-diameter outlet port is also hinged for use in both
the jointing and planing modes. The shroud has an internal, gravity-operated baffle plate
that helps direct the collection vacuum for maximum effectiveness. When the jointer bed
is up, the dust shroud is rotated up into a very traditional location for planer dust
evacuation. The planer section is now ready for use.
To go back to the jointer mode, rotate the dust shroud down, release the jointer table lock,
lower the table into position and then engage the two locking levers. The JET JJP-12
Jointer-Planer is ready for jointing operations in seconds.
Jointer Mode
Because both the machine modes use the same 12”
cutterhead, the jointer section is capable of face jointing
12”-wide stock. The 55”-long by 12”-wide cast iron infeed
and outfeed tables provide plenty of support for the big
project pieces.
The infeed and outfeed cast iron tables are individually
adjustable for height for the most flexibility. The maximum
cut depth is 1/8”. To insure long-term accuracy, we even
included full coplanar adjustment capability and complete
instructions in the manual for making this adjustment
should it become necessary.
The 43”-long by 6”-tall extruded aluminum smooth faced
fence makes accurate jointing easy. The fence is fully

12” jointing width capacity! The

and outfeed tables make this an
extremely versatile machine.
adjustable for material width using a pair of wide spread levers for maximum stability.
The fence face can be set to any angle from 0 to 45-degrees for precise bevel cuts. A
handy bevel scale and pointer are included on the fence mount.
Bridge Style Cutter Guard
The bridge style cutter guard may take a little getting used to
but is much safer than the “pork chop” shaped guards. This
style guard is simple to set up and with just a little experience
will actually be easier for many than dealing with the swingaway guards.
The bridge style guard is very
effective and easy to set up.
When jointing the wide face on boards, the cutter guard is
adjusted so that the board passes beneath it. Turning the knob
at its mounting base controls the height of the guard over the
cutter. This keeps the entire cutter area covered and prevents
the operator from pushing down directly over the cutter, something you shouldn’t be
doing anyway. For edge jointing operations, the guard is adjusted to allow the material to
pass between its end and the fence. Here again, the unused cutter remains covered
throughout the operation.
The bridge style cutter guard is needed only for jointing operations. The guard remains in
place without modification when the jointing table is rotated up to convert to the planer
mode.
Planer Mode
The JET JJP-12 Jointer-Planer is a fully capable thickness planer
with a 12”-cut width and handles a whopping 8 ¾” maximum
material thickness. The maximum full-width cut depth is 1/8”
with 5/32” being the maximum cut on narrower stock. Naturally,
lighter cuts put less stress on the wood itself and often produce
much better results. The 5500 RPM cutterhead speed means a
constant 20 FPM feed rate is a good balance between quick
material removal and a clean, smooth surface.
In planer mode the material feed roller system is engaged by
moving an exterior handle to the On position. That produces a
material feed rate of 20 FPM. (feet per minute) The control lever
is moved to the Off position when the JET JJP-12 Jointer-Planer
is changed to the jointing mode.
In the planer mode the JJP-
12 handles boards up to
12” wide with power to
spare.
The cutterhead assembly is fixed and includes a row of gravity-operated anti-kickback
fingers for safety. A serrated metal feed roller is designed to resist contamination and
maintain a consistent material feed rate for the best results. A rubber-covered outfeed
roller keeps the stock moving without marring the freshly planed surface.
The 21 ¼” by 12” planer table adjusts up and down through a large handwheel (with
spinner handle) on the infeed end of the JET JJP-12 Jointer-Planer while in planer mode.
A scale on the handwheel hub shows the amount of change partial turns create while a
full height scale with pointer shows overall cutter to table distance. The planer table is
locked with a lever-type handle.
The JET JJP-12 Jointer-Planer was designed to bring the much needed jointing and
planing capabilities to your shop in a single, space-saving 55”-long by 39 ½”-tall (top of
fence) and 32”-deep (fence at its widest setting) package. Because of its space saving
design and our focus on accuracy, function and durability, the JET JJP-12 Jointer-Planer
is as economical as it is versatile.
