The RO 90 DX multi-mode sander has a tool-less base design that lets it quickly transform from a round pad sander to a delta-shaped, random-orbit detail sander in seconds. Woodworkers can use it to treat rough surfaces, moving from random-orbit mode for fine-finish sanding, to rotary mode for polishing high-gloss surfaces. Front edge protectors help guard the workpice and extend pad life. It also features efficient dust removal. (888) 337-8600, FestoolUSA.com.
