Sumake’s 2-in-1 Electric Orbital Sanders come with either a 5 or 6-inch pad and in both non-vacuum and central vacuum models. With a variable free speed, the operator is able to select between 4,000, 7,000, 9,000, and 10,000 RPM. With no external power supply, these lightweight industrial sanders are leaders in the industry. The central vacuum orbital sanders hook into a vacuum used to collect dust, where our non-vacuum orbital system does not have a collection system. Sumake’s Industrial Electric Orbital Sanders/Polishers are engineered to last for years and require minimal maintenance.
