Palm-grip random orbit sander models ROS20VS and ROS10 offer new features and improvements versus previous models. The 2.2-amp tools include the Microfilter System, which traps particles as small as a half micron. The twist-off canister is now translucent for easier viewing of dust level, and its new anti-spillback design keeps dust inside. The tools' integral pad dampening system eliminates swirl marks on the workpiece, the company says, while the pliable microcellular backing pad provides for a smooth, fine finish on flat and contoured surfaces. The HookTight disc attachment system features 35,000 hooks, two times the standard number, with special gripping geometry that makes it hard for dust to get in between the disc and the hooks. The ROS20VS offers variable speed from 7,500 to 12,000 rpm; the ROS10 delivers 12,000 rpm. 877-267-2499. www.boschtools.com
