Features:

• High-Efficiency Brushless Motor: GoYwato power drill cordless features a built-in brushless motor with 55A overload protection, delivering greater efficiency, stability, power, and quieter operation—spark-free with a 150% longer motor lifespan. Our cordless hammer drill has a maximum torque of 1239in·lbs/140N·m and peak impact rate of 24000IPM, it boosts power by 80% while reducing noise by 60% during operation, ensuring effortless completion of every task. (Note: If you buy additional drill bits for medium to large-scale projects, monitor the electric drill's operating time and work intermittently. Continuous overload operation may damage the impact drill)
• 21V 4000mAh Lithium-Ion Battery: This cordless drill set comes equipped with two 4.0Ah li-ion batteries and one fast charger. Each battery takes 2.5 hours to fully charge, with a runtime of 135 minutes per fully charged one. Our batteries feature 91A overload protection, over-temperature, over-charge, and over-voltage protection. This ensures stable power delivery to the electric hammer drill while eliminating the hassle of running out of power during work, enabling more efficient and effortless operation—a truly worry-free design. The charger's indicator light is green when connected to power, red during battery charging, and green again when the battery is fully charged
• Low & High Speed: This brushless hammer drill features 2 speed settings. The L speed(range 0-700RPM) is ideal for soft materials, or for tightening self-tapping screws and small screws. Set the torque to a low value and carefully monitor the speed—excessive speed may damage the original accessories. The H speed(range 0-2300RPM) is suitable for hard materials like metal and concrete, or tightening hex screws and large bolts, torque can be set to higher values. Pressing the speed trigger switch deeper increases the hammer drill's rotation speed. This dual-speed adjustment precisely meets various task requirements while effectively preventing over-driving and material damage
• 20 Torque Settings + 3 Operating Modes: This cordless drill features a 20-stage adjustable clutch and 3 operating modes—screwdriving, drilling, and hammer drilling—to accommodate diverse applications. Higher torque ring numbers indicate greater torque output, suitable for materials or screw types of varying hardness. Torque settings 1-6 are ideal for screwing into soft materials like plastic or wood; settings 8-15 are suitable for drilling metal and red bricks; settings 16-20 can drill lightweight concrete. Our battery concrete drill can bore holes up to 25mm diameter in 40mm thick steel plates and 100mm diameter holes in wood. (Note: Do not overload the battery drill)
