Alternative Views:

Loaded with features, the 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 diverse jobs. The belt head has an indexing pin with stops at 0, 45° and 90° and the head lock allows use at any angle in-between. Removing the top guard allows contour sanding and the cast iron tables with miter gauge slots and positive stops make set-up fast, accurate, and simple for any angle.
