Powermatic 1791291K Model 31A Belt/Disc Sander

The Powermatic 1791291K Model 3A belt/disc sander is a versatile woodworking--and metalworking--machine. The belt unit features tool-free belt positioning, with locks at 0, 45 and 90 degrees. The patented articulating table angles downward from 0-45 degrees and can handle both horizontal and vertical work. It is also effective for compound angle sanding and edge work and doubles as a backstop fence for backstop work. On the disc sanding side, a precision-balanced 12-inch disc and large tilt-table surface provide accurate angle and pattern work. The table angles from +15 to -45 degrees with a miter slot. Both tables are made from precision-ground cast iron and can accommodate a full range of angles. The belt/disc sander provides fast and accurate belt tension and tracking controls. The cast iron platen and solid crowned aluminum drums resist heat build-up and help ensure steady belt tracking, while a removable top guard allows for contour sanding. The belt/disc sander itself is constructed of rugged cast iron, too. This helps reduce vibration and makes the machine well-suited for both metal and woodworking use. A single, internally connected, four-inch dust collection port keeps everything clean and makes it easy to hook the belt/disc sander into your shop's dust collection system. --Carl Thress
