Makita delivers corded grinding performance without the cord with the 18V X2 LXT® Lithium-Ion (36V) Brushless 7” paddle switch Cut-Off/angle Grinder with electric brake and AWS™ (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 XAG22ZU1 is ideal for grinding and cutting a wide range of materials including tile, concrete, pipe, conduit, and more. For improved efficiency, it’s equipped with auto-start wireless system (AWS™) technology. Aws™ utilizes Bluetooth® technology for wireless communication between the tool and dust Extractor (sold separately). When the trigger is engaged, The aws™-equipped dust Extractor powers-up. When the trigger is released, the dust Extractor powers down. Aws™ is intelligent communication that eliminates cords and excessive noise since the dust Extractor runs only when the tool is running. Additional features include the BL™ Brushless motor, Active feedback-sensing technology (aft®), and an electric brake that stops the grinding or Cut-Off Wheel in 2 seconds or less. The BL™ Brushless motor eliminates carbon Brushes, enabling the motor to run cooler and more efficiently for longer life. Aft® turns the motor off if rotation speed suddenly slows or the wheel is forced to a stop. 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.
