The Makita 9227C is a Factory Reconditioned 7 inch Electronic Variable Speed Sander-Polisher. It uses electronic speed control to maintain a constant 600 to 3000 RPM, even under load and that combined with multiple speed settings results in little risk of burning paint. The polisher converts easily to a sander and quick-change hook-and-loop sanding pads eliminate clamping, bending and tucking. Its handle provides secure, comfortable grips for use at any angle and the lock-on trigger helps to go long distances with minimum fatigue.
