The Makita DHR400ZKU is a heavy-duty SDS-MAX rotary demolition hammer, delivering exceptional power with 36V performance via two 18V LXT batteries. Built for the toughest drilling and chiselling applications, this cordless beast offers a 40mm capacity in concrete, a high-efficiency brushless motor, and integrated AWS (Auto-Start Wireless System) for dust extraction control.
Engineered for demanding construction tasks, the DHR400ZKU features Anti-Vibration Technology (AVT) and a soft no-load mode to reduce vibration during idling. It also includes Active Feedback sensing Technology (AFT) to shut the tool down if the bit jams, ensuring user safety. The included wireless unit allows automatic communication with compatible AWS dust extractors for remote activation.
