This 21V lithium-ion brushless rotary hammer is an industrial-grade tool designed for drilling and chiseling in concrete, stone, and other hard materials.

Equipped with a high-power brushless motor and an impact mechanism, it allows free switching among drilling, chiseling, and impact modes to suit different job requirements.

The vibration-damping design significantly reduces hand fatigue during extended operation.

Built-in overheat and overload protection, with precisely adjustable no-load speed and impact frequency, make it a core tool for renovation and plumbing/electrical work.

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.

The XJ.728 21V lithium-ion high-magnetic brushless rotary hammer is a heavy-duty industrial-grade hammer from the Xiaojia brand.

Featuring an upgraded high-magnetic brushless motor with enhanced power and durability, impact energy is increased to 2.8J, capable of heavy-duty drilling in high-hardness concrete, granite, and other hard materials.

It supports three-mode switching, with an extended vibration-damping handle for greater comfort during prolonged operation.

The built-in intelligent control system automatically adjusts power output based on load resistance, and triple safety protection makes it a core heavy-duty tool for large-scale renovation and engineering projects.
