The Delta PEC Disc Sander, No. 31-140, is made with heavy duty cast iron construction, with a  steel bevel assembly supporting the table and a 12", 80 grit abrasive disc. The 1/2 HP, 120V motor is designed to last long with smooth performance. The sander features top-mounted manual brakes, a tilting cast-iron table with left and right positive stops at 22.5 degrees, 45 degrees and 90 degrees, and a integral dust collection fan that draws dust away from the table and into a 2 1/4" hose.
