Cordless Grinder Machine, Brushless Motor, 4.5 inch (115mm), 18V, 2.5kg

Makita DGA455RTJ Cordless Grinder Machine
The Makita Cordless Grinder Machine DGA455RTJ 115mm, is powered by an 18V Li-ion battery and Brushless motor with high power that provides up to 8,500 rpm for efficient use. The Cordless Grinder Machine is perfect for prolonged use in manufacturing or production applications. This Cordless Grinder Machine is designed with a slim and ergonomic soft rubber grip that absorbs vibration for comfortable operation. It features an Anti-restart function that prevents accidental tool start-up during battery replacement, while the LED charge level indicator displays the remaining battery power. 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 Cordless Grinder Machine Features:

Excellent Performance is as powerful as the AC model with a highly enhanced Brushless DC motor.
Paddle type on/off switch and Anti-restart function.
AFT function shuts down the tool if the rotation speed suddenly slows down.
Automatic speed control: Automatically changes the cutting speed according to load conditions for optimum operation.
Handles heavy loads with Excellent Cooling Function.
High efficiency and more work amount by Brushless DC motor.
