This 25-50 Drum Sander with Closed Stand provides the largest work area of any open-ended drum sander available. It features INTELLISAND technology that maintains its operational speed to produce consistent results. The SuperMax 25-50 drum sander has an extra-wide bed that supports materials up to 25 inches wide. You can complete two passes for materials that measure up to 50 inches wide. A single nut adjusts the height of the head and maintains the height while you work. Index adjustments specify the SuperMax woodworking drum sander's mode so that you can maintain consistency over large areas with one or two passes. The tool's bolted drum carriage keeps the head where you need it, even when you install new abrasives, and it comes with a wheeled stand for support.
