The XJ.709 21V lithium-ion high-magnetic brushless rotary hammer is an industrial-grade hammer from the Xiaojia brand. Equipped with a high-magnetic brushless motor, it delivers 30% higher torque and 20% lower energy consumption compared to standard brushless motors. It supports three-mode switching (drill, chisel, hammer) with an SDS-plus quick-change chuck for tool-free bit changes. The built-in vibration reduction system significantly reduces hand fatigue, and triple protection (overheat, overload, under-voltage) makes it suitable for concrete, stone, wood, and various materials. It is a top choice for renovation and plumbing/electrical work.
