The Makita 2" AVT Rotary Hammer (HR5212C) has over 45% less vibration than the previous model with enhanced anti-vibration technology (AVT), a synchronized three-component system for significantly less vibration. The result of the enhanced AVT is a category-leading vibration rating of 9 m/s². The powerful 15 AMP motor delivers 19.1 joules (14 ft.lbs.) of impact energy. An added feature is the option of lock-on or trigger-activated in the chipping only mode, with a push button start/stop control for more convenient operation. The HR5212C is engineered for a range of concrete applications including drilling/coring through-holes for pipes, setting larger anchors, securing tilt-wall supports, small chipping applications, and more.
