Makita Cordless Rotary Hammer DHR400ZKU The Cordless Rotary Hammer Makita DHR400ZKU 40mm is powered by two 18V Li-ion batteries with a high-power brushless motor, which provides up to 500 rpm, It has two modes of operation (Rotary Hammer and Rotary Only), making it suitable for various applications. This Cordless Rotary Hammer has an Auto-start Wireless System (AWS) that connects to compatible vacuum cleaners via Bluetooth, and its Low vibration feature reduces hand-arm vibration, making it easier to use for extended periods. Additionally, the Cordless Rotary Hammer Extreme Protection Technology protects it from dust and dripping water, making it ideal for outdoor use. Also, the active feedback sensing technology automatically turns off the motor if rotation is suddenly forced to stop, while the variable speed feature allows you to control the speed. The torque limiter reduces gear damage, and the reversing feature helps quickly remove screws and other fasteners. The dust collecting system ensures a cleaner work environment and provides long-lasting reliability. Powerful Features: Lithium Ion Extreme Technology: The LXT System was the world’s first 18V lithium-ion cordless tool system. LXT Products deliver premium power and run time for consistent results in commercial applications. These products are the one-battery solution for contractors that require a cordless tool system to be more provides longer work time for increased performance and productivity to help them solve problems, job after job. It has a charge time of just 45 minutes when using the Makita rapid charger with the added convenience of an LED charge level indicator. The charger communicates with the individual cell in the battery and controls current, voltage, and temperature. Both rapid and optimum charge are achieved making battery life longer. Brushless motor: The Makita Brushless motor is precision-engineered to be up to 50% more efficient than a brushed model. This means a fully charged 18V lithium-ion battery will last almost twice as long as a product running on a standard motor. Makita Brushless tools bring with them greater productivity, as not only do they last longer but they charge faster, thanks to the power of lithium-ion. Makita-built Brushless Motor eliminates carbon brushes, enabling the motor to run cooler and more efficiently for longer life because of no friction loss and reduced heat production caused by brushes. Extreme Protection Technology: Extreme Protection Technology (XPT) is a protective seal inside the tool engineered to provide improved water resistance by channeling water and dust from the tool’s key internal components. For use in outdoor applications or harsh environments, protection from dust and dripping water is enhanced compared with other models. Auto Start Wireless System: Auto Start Wireless System (AWS) uses Bluetooth technology for wireless power-on and power-off communication between the equipped tool and dust extractor. Once connected via AWS, your dust extractor will automatically power on or off when your cordless tool starts or stops, running only when your cordless tool is in use. Anti-vibration technology: Anti-vibration technology is an internal counterbalance system that greatly reduces vibration with 70% vibration reduction technology, we know from experience that the larger the power tool, the harder it is to control it while working. Now, thanks to the AVT system, working with a hammer or demolition hammer has become much easier and does not require such a strong hand from the user. Active Feedback Sensing Technology: Smart function to minimize the effect of kickback. Shuts down the tool, if the rotation of bit or disc is suddenly forced to stop. Active Feedback Sensing Technology uses an onboard accelerometer to measure rotation and electronically turns off the motor if rotation is suddenly forced to stop. In addition, the torque-limiting clutch is engineered to prevent gear damage by automatically disengaging the gears. Variable speed: Variable speed control allows the user to match the speed to the application they are working on. Brake: Electronic brake stops the bit in 2 seconds quickly and easily for increased operator safety and avoiding accidents. Reversing: After drilling, setting the bit direction to reverse spins it counterclockwise to help it come out of the hole cleanly and easily. You'll also use reverse mode to quickly remove screws and other fasteners. Torque Limiter: A torque limiter is a built-in clutch that reduces gear damage by disengaging gears if the bit binds. Constant Speed: Constant speed control automatically applies additional power to the motor to maintain speed under load. Dust Collecting: The dust collector is designed to reduce the amount of dust produced during cutting and concrete dust generated during drilling on the job site, allowing you to work efficiently and comfortably. Built-in Job Light: Built-in LED light with pre-glow and afterglow functions illuminates the work area for better visibility.
