The Makita HM004GL401 is a cordless 70-lb breaker hammer engineered for heavy concrete demolition, roadwork, and industrial maintenance where corded reach is limited or a generator is impractical. Powered by two 40Vmax XGT batteries in series (80Vmax), it delivers up to 72.8 Joules (53.7 ft-lb) of impact energy—performance on par with a 15-amp corded demolition hammer, without the cord. A purpose-built brushless motor, Anti-Vibration Technology (AVT) housing with counterweight, and Soft Start/Soft No-Load controls improve handling, reduce vibration to 6.5 m/s², and help operators place blows accurately.
For jobsite productivity, the kit includes (4) 8.0Ah 40Vmax XGT batteries, a dual-port rapid charger, and Makita’s Premium Hammer Cart with stair-climber rails and on-board storage for bits, batteries, and charger. Extreme Protection Technology (XPT) improves dust and water resistance, while AWS® (Auto-Start Wireless System) compatibility enables wireless activation of a compatible dust extractor. Twin LED work lights with pre-glow/after-glow aid visibility. With a compact battery-below-handle layout for clear sight to the bit tip, this breaker is designed for precise chiseling, trenching, and slab removal in demanding environments.
