Straightline Action. Designed primarily for the Woodworking industry, the 2025 mini-straight line sander allows the operator to level stock when using coarser sandpaper grits or sand between topcoat applications using finer sandpaper grits. Its straightline action eliminates sanding "pigtails" created by most random orbit sanders. The convenient 4 1/2" x 9" pad insures a large sanded area. Standard 9" x 11" sandpaper sheets can be cut in half for use on the 2025. When using Velcro backed abrasives, order the model 2025H with the Hookit pad.
