FLEX has introduced a new Rotary Drywall Sander series built around a carbon fiber shaft—an industry first—starting at 6.2 lbs. for the corded model. The brushless motor is positioned in the T-handle rather than the head, improving balance and eliminating maintenance concerns from fine drywall dust. A 160-degree pivoting head provides maneuverability on walls and ceilings, and an optimized head design channels dust away from the work area. A vacuum hose adapter is included on corded models.

Two 120V corded configurations are available now: the FC3731-Z (without light ring) at $649.99, and the FC3731-ZA (with integrated LED light ring) at $799.99. The light ring, which illuminates the work surface to reveal imperfections in real time, is also available separately as the FT371 attachment for select models. The corded sanders carry a one-year limited warranty with registration.

Two 24V cordless configurations—the FX3731-Z (tool only) and the FX3731-2C kit with two 5.0Ah batteries and a 280W rapid charger—are available starting July 2026. Cordless models carry a five-year limited warranty with registration.

All FLEX products are available at Amazon and authorized dealers.
