31A Belt Disc Sander
The Gold Standard Since 1921.
Loaded with features, the new
31A from Powermatic can tackle
the most demanding tasks. Full
cast iron construction allows both
metal and woodworking to be
done on the same machine and
the Integral Dual Dust Port keeps
both belt and disc portions clean,
extending abrasive life. ■The
articulating table mounted on
the 6"x 48"belt sander head can
be used vertically, horizontally,
or angled to accommodate
any job. The belt head has an
indexing pin with stops at 0, 45
and 90 degrees and the head
lock allows use at any angle in
between. ■Removing the top
guard facilitates contour sanding
and the cast iron tables with
miter gauge slots and positive
stops make set-up fast, accurate,
and simple for any angle.
