Makita delivers corded grinding performance without the cord with the 18-Volt LXT Lithium-Ion Brushless 4-1/2 in. / 5 Cut-Off/Angle Grinder with Electric Brake (tool only, battery and charger sold separately). It’s powered by a Makita brushless motor for a 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 XAG16Z is ideal for grinding and cutting a wide range of materials, including tile, concrete, pipe, conduit, and more. Additional features include an electric brake that stops the grinding or cut-off wheel in 2 seconds or less and Electronic Torque Control that turns the motor off if the rotation speed suddenly slows or the wheel is forced to a stop. The variable speed control dial allows manual RPM adjustment (3,000-8,500), allowing the user to match the speed to the application. It’s part of Makita’s expanding 18-Volt Lithium-Ion system, the world’s largest cordless tool system powered by 18-Volt Lithium-Ion slide-style batteries. Makita 18-Volt Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger.


  • The electric brake stops the grinding or cut-off wheel in 2 seconds or less for maximum productivity
  • Active Feedback sensing Technology (AFT) turns the motor off if rotation of the wheel is suddenly forced to stop
  • Automatic speed change technology adjusts speed and torque during operation for optimum performance
  • BL brushless motor eliminates carbon brushes, enabling the BL motor to run cooler and more efficiently for longer life
  • The variable speed control dial allows manual RPM adjustment (3,000-8,500) to match the speed of the application
  • Soft start suppresses start-up reaction for smooth start-ups and longer gear life
  • Anti-restart protection engineered to prevent motor start up when the battery is inserted with switch locked on
  • An efficient BL brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge
  • Electronically-controlled BL brushless motor efficiently uses energy to match torque and RPM to the changing demands of the application
  • 3-stage LED gauge indicates battery charge level
  • Spiral bevel gears for smoother rotations and a more efficient transfer of energy
  • Wire mesh intake covers are engineered to prevent debris from entering the motor
  • Extreme Protection Technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions.
  • A rubberized soft grip provides increased comfort on the job
  • Compact and ergonomic design at only 14-1/4 in. L
  • Weighs only 5.7 lbs. with battery (battery not included) for reduced operator fatigue
