Power from the motor is delivered through a Poly-V belt running on high-precision
multi-groove pulleys. The Poly-V belt is known for smooth, slip-free operation as well as
very low heat generation. We also use a Poly-V belt to transfer power between the
spindle and idler pulleys.
Spindle Speeds
The JET JDP-17DX
Drill Press has 16
spindle speeds from 230
RPM to 3,630 RPM!
This extensive range of
spindle speeds is more
often found on high
priced machines but
gives the JET JDP-
17DX Drill Press
maximum compatibility with drill bits and materials.
The multi-=step pulleys (left) generate the wide speed range. Note the chart on the
cover that clearly shows the configurations and speeds. Power is transmitted
through a Poly-V belt (right) and precision pulleys for smooth, slip-free operation.
This large range of speeds is generated by a set of three stepped pulleys, each with four
positions. Moving the Poly-V belt among the positions in various combinations produces
the various speeds. A flip-open top provides complete access to the pulleys. A large label
within the cover has graphics showing all 16 spindle speeds and the belt positions that
generate each of them.
Powerhead Features
At the heart of any drill press is the spindle. The JET JDP-17DX Drill Press is equipped
with a massive, 2”-diameter spindle that offers exceptional stability. The spindle has a
full 4 3/8” of travel to handle deep
drilling operations with ease.
Swing capacity at the spindle is 16-
1/2”! A tool free depth stop
functions anywhere in the spindle
travel to make repetitive drilling
jobs easy and very accurate. This
system allows stopping the spindle
at any height or holding it at any
depth. The spindle runs in high-
quality, permanently lubricated ball
bearings to insure smooth running
and a long life.
The large diameter downfeed handle (left) make operating easy.
The handles can be mounted in a second hub on the left side of the
powerhead (right) just behind the easy-to-use depth stop system
