sander is designed to do intricate detail sanding. It will
sand the straight, angled, curved, convex or concave edges
and ends of workpieces quickly and accurately. A unique feature
of the strip sander is its ability to sand the internal edges
of round and oval picture frames, decorative shelf supports
and other projects that have been cut out using the piercing
cut method on a scroll saw or jigsaw. You can also use the
strip sander to polish metal and grind tools.
