The Milwaukee 3771-21 M18 FUEL™ STRIKER™ Hammer Chisel is the world’s first cordless hammer chisel, engineered to deliver long-barrel pneumatic striking force without a compressor or air hose. It brings pneumatic-level impact to mobile shop and field service work for tasks such as suspension teardowns and ball-joint removal.
Powered by a POWERSTATE™ Brushless Motor, the tool delivers 7 Joules of striking force, matching the output of long-barrel pneumatics at 145 PSI. Users can select from three modes and use the variable-speed trigger and ramp-up setting to precisely control strikes from a gentle start through full-speed impact.
Built for integration with the M18 system, the STRIKER™ uses a .401” round-shank twist chuck for fast bit changes and is compatible with M18 REDLITHIUM™ batteries and chargers. Additional features include REDLINK PLUS™ intelligence, a patented battery isolation system, and a targeted LED work light to improve visibility while limiting shadows.
