Makita XAG04Z 18V LXT? Lithium-Ion Brushless Cordless 4-1/2? / 5" Cut-Off/Angle Grinder, Tool Only Makita delivers corded grinding performance without the cord with the 18V LXT Lithium-Ion Brushless 4-1/2"/ 5? Cut-Off/angle Grinder (tool only, battery and charger sold separately). it's powered by a Makita Brushless motor for longer run time, increased power and speed, and longer tool life. For the most demanding applications, Makita?s exclusive automatic speed Change technology automatically adjusts speed and torque during operation for optimal performance. The XAG04Z is ideal for grinding, cutting and sanding a wide range of materials including tile, concrete, pipe, conduit, and more. It's part of Makita?s expanding 18V Lithium-Ion system, the world?s largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. Makita 18V Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita created Star protection Computer controls. Star protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT and compact Lithium-Ion batteries with the Star symbol on the battery indicating Star protection inside. Features Automatic Speed Change technology adjusts speed and torque during operation for optimum performance Active Feedback-sensing Technology (AFT) turns the motor off if rotation of the wheel is suddenly forced to stop The BL Brushless Motor eliminates carbon brushes, enabling the BL Motor to run cooler and more efficiently for longer life Efficient BL Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge The electronically-controlled BL Brushless Motor efficiently uses energy to match torque and RPM to the changing demands of the application USA SHIPPING estimates delivery times and we work to get your item to you as quickly as possible and within those times, but please know it may take slightly longer than the estimate.
