The M18 FUEL™ ONE-KEY™ SAWZALL™ builds on the performance of the M18 FSZ by adding advanced ONE-KEY™ technology for smarter tool control and security. Connecting via Bluetooth® to the ONE-KEY™ app, users can customise tool settings for specific applications, save up to three custom configurations, and optimise cut performance for longer blade life and cleaner, faster cuts. Enhanced safety and precision features such as adjustable soft start, cut optimisation, and an automatic blade brake are combined with ONE-KEY™ tracking, remote locking, and full compatibility with all MILWAUKEE® M18™ batteries for a powerful and connected cutting solution.
