JET JWP-15DX & JWP-15HH, 15” Planers
The ability to create accurately dimensioned wood with
parallel faces is crucial to virtually any woodworking task.
Producing an ultra smooth, tear out free surface at the same
time is a welcomed bonus. The JET JWP-15DX and JWP15HH have been designed to handle these tasks with the
accuracy, durability and repeatability you want. Robust
construction, a powerful motor, a rock solid table and a userfriendly knife changing system gives these planers the
durability and value you need.
Built around a fully enclosed, welded steel base cabinet, the

machined iron castings to insure durability and precise,

repeatable operation. A heavy-duty caster system built into
the base makes moving the 517-lb JET JWP-15DX around the shop easy. A foot-operated
brake locks the casters to keep it stationary during use.
Should lifting be necessary, four pull-out rods are built into
the cast iron base. These rods provide safe lifting points for
straps or forklift arms.
A powerful 3HP, (continuous duty rating) 1PH, 230V TEFC
(totally enclosed fan cooled) motor is mounted within the base
cabinet. Power is transmitted to the fixed cast iron cutterhead
housing by three v-belts that turn precision-machined pulleys.

spinning off a pair of finger-operated knobs. The motor is
operated and protected by a true magnetic switch mounted on
the head assembly within easy reach.
Quick-Change Knife System
The JWP-15DX features 3 knives and our "Quick change knife system". The
knives each have 2 cutting edges so that they can be flipped when one side becomes
damaged or dull. The savings in time and money this feature brings is obvious, but there
is more.
An important feature of the JET JWP-15DX is how easily the
knives are changed and set. A specially designed mounting
and alignment system eliminates one of the most frustrating
aspects of using many planers - changing and aligning its
knives.
When a knife becomes dull or damaged all one has to do is
remove the 8 retaining screws and carefully remove it. The
cutterhead has two precisely machined and located pins in
each knife seat that mate exactly with two precisely

machined and located slots in the knife. When changing or flipping a knife simply place
it over the pins on the cutterhead seat, replace and tighten the 8 screws and it is
automatically aligned and ready for use. No further adjustment is required.
JWP-15HH with the Helical Cutterhead
While designing the JET JWP-15HH we developed a

helical cutterhead with carbide inserts.
The JET JWP-15HH cutterhead is so effective because
its 68 carbide inserts are arranged in four spiral-shaped rows. The inserts have a 4” radius
ground into them and are mounted so they approach the wood at a 14-degree angle. That
creates a true shear cut that eliminates much of the impact and the resulting fiber
disturbance common with other cutterhead designs. Also contributing to this excellent
surface finish is the profile of the space between the rows of carbide inserts. These areas
are specially designed to carry chips away from the cutting area and eject them before
they cause any problems for your work surface.
This helical cutterhead cuts so efficiently that it makes surprisingly little noise when
cutting wood. In fact, it is so quiet, that new users often think that the JET JWP-15HH is
not cutting wood at all! That is until they see the freshly planed surface emerge from the
other side.
The helical cutterhead inserts are precisely machined from solid high-grade carbide, each
with four identical cutting edges. If an edge goes dull or is damaged, you simply index it
to the next cutting edge! Each insert has a marking at one edge that makes indexing all or
any number of them the same way very easy.
Because the inserts and the seats into which they fit are
so precisely machined, there is no adjustment or
“fitting” necessary. Indexing or replacing an insert
takes just seconds. Simply loosen the T25 Torx screw
(wrench included), turn the insert to its new position
and tighten the screw.
The durability of the carbide combined with the low
impact, shear cutting action means they have an
extremely long life that substantially exceeds that of
straight blades. The potential life span of these carbide
inserts means that many wood workers may go years
before having to index them. Should a hidden piece of
metal be encountered and actually damage a few of the

carbide inserts only those need to be indexed or
replaced. Just in case you accidentally plane a metal object, we include a package of ten
spare inserts and a wrench with the JET JWP-15HH.
Feed & Rollers
The JET JWP-15DX and JWP-15HH have two material feed rates
–20 FPM (Feet Per Minute) used primarily for rough
dimensioning and 16 FPM to increase the cuts-per-inch to create a
silky-smooth surface. A push/pull knob shifts between the feed
rates on the fly. The rollers are driven by a gear and chain drive
with an automatic chain tensioner, housed in a cast iron case. The

gear section runs in an industrial style oil bath for maximum
control over long-term wear.
For the ultimate in dependability, we designed a serrated steel
infeed roller and a smooth steel outfeed roller. Both rollers and the chip breaker are
precisely set at the factory but have user accessible adjustments that make it easy to keep
these planers perfectly tuned in years to come. We also included infeed and outfeed roller
spring tension adjusters that are accessible without having to
disassemble the cutterhead housing covers. The operators’
manual included has a full set of illustrated instructions for
making these adjustments.
To enhance operator safety, we added a row of closely spaced
anti kickback fingers. These steel fingers are gravity operated
and require no adjustment. They automatically engage the
wood as it enters the cutterhead and help prevent it from being

kicked out.
While the JET JWP-15DX and JWP-15HH are capable of 3/16”-deep cuts on most stock
widths, a limiter plate at the center of the cutterhead that limits full-width cuts to 1/8” or
less. Controlling full-width cut depth avoids applying excessive strain to the machine but
also prevents damaging the wood. Deep cuts are far more likely to produce chipping and
tearout because of the extraordinary stress applied to the wood fibers.
Dust Collection
The efficiency of the JET JWP-15DX and JWP-15HH
means they are capable of generating large quantities of
dust and chips that must be evacuated to maintain
performance at the cutterhead. We recommend a 500600CFM (cubic feet per minute minimum) dust collector
to handle the flow of chips properly.

JWP-15DX that creates a short, direct path for the debris
directly from the cutterhead. The hood terminates with a
4”-diameter port that is angled to the side so the dust
collector hose does not interfere with the stock as it
exits.
The JET JWP-15HH actually takes this a step further. The helical nature of the cutter
head actually ejects debris at an angle, directly toward the exit of the angled dust hood.

A pair of rollers set into the primary table surface below the cutterhead help maintain
smooth movement of rough stock through the JET JWP-15DX and JWP-15HH. The
above table height of the rollers is easily adjustable.
We also include a pair of 14”-long by 15 1/2”-wide roller extension tables that increase
the overall table surface to 48” in length. The extension tables mount to the primary table
with bolts but have set screws below each of them that allow precise alignment of the
rollers to the primary table. This is a far more efficient system than trying to shim the
extension tables to bring them into alignment with the primary table surface.
Note: The JWP-15HH planer comes with solid cast iron extension tables in place of the
roller versions supplied with the JWP-15DX. The cast iron extension tables mount
identically to the roller versions.
Top Rollers

added a pair of material rollers to the cutterhead housing.
