The updated Snap-on sanders have a reduced vibration from the heavy-duty front spindle, a balanced crank mechanism and a soft, multi-position grip. Offered in both 3” (PSOF4325) and 6” (PSOF4625) lengths in a 3/32" finishing pattern, and in 5” (PSO4525) and 6” (PSO4625) lengths in a 3/16" pattern. Each sander’s motor is sealed with a patented O-ring and bearing shield to keep dust and debris from entering critical components. Sanders also have a multi-position regulator and Kevlar vanes to help reduce moisture and oil on the work area.
