The Milwaukee Tool M18 FUEL 7” Variable Speed Polisher, No. 2738-22, provides users with nearly 2,200 rpm. With an ergonomic design for speed control, balance and weight, the polisher is designed to distribute more of its weight over the pad, providing natural pressure on the surface area, and be more comfort to the user. The 4.9-lb, 19.8" long polisher offers a variable speed dial and trigger and a lock-on/lock-off feature. The RedLithium XC5.0 battery provides portability, and on a full charge, the M18 FUEL 7” Variable Speed Polisher can complete a full-size car.
