FLEX FC3321-Z Corded Brushless Random Orbital Polisher
$100+
See current price on Amazon
FLEX's 2026 corded random orbital: a brushless motor with constant-speed control that holds RPM under pressure, an 11-position speed dial, vibration suppression and a redesigned gear head that cuts the high-frequency whine older FLEX tools were known for. It is the corded, free-spinning alternative to the forced-rotation XCE for detailers who want FLEX build quality in a conventional long-throw DA.
