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.
