Verdict
The DEWALT DWE6401DS Disc Sander is appreciated for its powerful and efficient sanding capabilities, perfect for large-scale projects. However, users have noted significant quality and design issues, particularly with the dust collection system and durability over extended use. These factors may lead some users to explore alternatives, such as Makita, especially if excellent customer service and reliable performance are top priorities for you. While the warranty offers some reassurance, potential delays in repairs should be considered in project planning.
