Steel Drums
The POWERMATIC
Dual Drum Sanders
feature dual steel drums
spinning at a consistent
1700-RPM that are
precisely machined and
then given a hard
durometer rubber coating
that ensures a flat, non-
marring surface. These
6”-diameter steel drums
have the strength to resist
flex during sanding for
maximum accuracy and consistency.
Installing abrasive strips (left) is easy and secure with the wedge retainers. The rear drum
is adjustable (right) using this knob to compensate when using different abrasive grits
than on the front drum.
The rear drum is independently adjustable, which allows fine-tuning, especially when it is
equipped with a different grit paper than is on
the front drum. A special graduated knob at
either end of the rear drum makes setting this
height for the abrasive grit being used easy and
accurate. We include a handy chart on the
cabinet below the adjustment that shows the
correct settings for the various grits.
The pressure rollers are easily adjusted with these tough but
simple mechanisms located up top for easy access.
The abrasive strips can be purchased ready to
cut or can be cut in your shop. The strips are
secured to the drums using simple but very
tough and highly effective wedges. Tuck the end
of the paper in, insert the wedge and tighten the
retaining bolt.
The pressure rollers are also fully adjustable. The easy to use adjusters are located on top at
either end of the rollers for easy access. These adjusters are designed to be rugged and to hold
their adjustment during long periods of use. The full adjustment procedure is described in the
instruction manual.
The conveyor belt runs on a precision cast iron table for flatness and
consistency.
