Makita Angle Grinder Machine DGA454RTJ The Cordless Angle Grinder Machine Makita DGA454RTJ is a powerful tool that runs on an 18V lithium-ion battery and a high-powered brushless motor. It can deliver up to 8,500 rpm, making it more efficient for use in various situations, and can automatically adjust its speed based on the load, ensuring optimal performance. The Angle Grinder Machine has a slim design and a soft, comfortable rubber handle that absorbs vibration, providing a more comfortable experience for the user. The Cordless Grinder Machine features a flashlight LED that displays the remaining battery charge level. Additionally, the Soft start feature gradually increases speed to eliminate start-up shock, Extreme Protection Technology (XPT) offers maximum protection against dust, debris, and liquids for optimal performance in extreme conditions, Automatic torque Drive Technology (ADT) feature adjusts the torque and speed according to the load condition, Active Feedback Sensing Technology automatically turns off the motor if sudden stoppage occurs. 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 provide 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. Soft Start: Soft start prevents start-up reaction to ensure smooth starting, longer gear life, and better accuracy when starting work. 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. Automatic Torque Drive Technology: Automatic torque Drive Technology adjusts speed and torque for optimal performance, even in the most demanding applications. During operation, if the tool is put under heavy load, Automatic torque Drive Technology detects the added demand and applies more torque and speed to finish the job. 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. Makita Grinder Machine Features: A powerful and top-notch performance, similar to an alternating current motor, thanks to its greatly improved brushless direct current motor. It is equipped with a slide-type on/off switch and an anti-restart function for safety. AFT function shuts down the tool if the rotation speed suddenly slows down. The cutting speed can be automatically adjusted according to the load for ideal cutting operations. It can handle heavy loads with its excellent cooling function and high efficiency, thanks to the brushless DC motor, which allows for more work to be done.
