Before the introduction of the 25-50 Drum Sander, the SuperMax 50x2 Dual Drum Sander (retail: $12,000) was the only available method to drum sand pieces of that width. Based on the experience with designing the awarding-winning 19-38 Drum Sander, SuperMax wanted to push the limits of sanding equipment further than ever thought possible. SuperMax wants its 25-50 Drum Sander to be the largest open-ended drum sander on the market.
