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.
Our Quick-change knife system
makes this once frustrating task
quick, simple and automatically
accurate. We include a pair of
magnetic tools - shown here
removing a knife retainer plate –
that helps prevent nicked fingers!
JWP-15HH with the Helical Cutterhead
While designing the JET JWP-15HH we developed a
criteria for a unique cutterhead that would insure the
unmatched performance and reliability. That design
specification meant the choice was very simple - 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.
Our helical head with its spiral rows of
carbide inserts creates ultra smooth
surfaces yet has an exceptionally long
cutter life.
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.
