Driven by a high-torque 14.5-amp motor producing 9.3 ft-lbs of impact energy, this 20-lb corded hammer features a dual-mode selector to transition smoothly between rotary hammer drilling and hammer-only chiseling operations. An integrated Turbo Power mode directs a 20% power boost directly into chiseling applications, while a multi-stage Vibration Control system combines a decoupled main handle and tuned mass dampener to reduce harmonic fatigue during all-day commercial anchor setting and slab breaking.\n  \u003c\/p\u003e\n\n  \u003ch3 style=\"color: #004b87;
