Makita delivers corded grinding performance without the cord with the 18V LXT® Lithium-Ion Brushless 4-1/2" / 5” Paddle Switch Cut-Off/Angle Grinder with Electric Brake (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 XAG20Z is ideal for grinding and cutting a wide range of materials including tile, concrete, pipe, conduit, and more.

Key Features

• 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
• The BL™ Brushless Motor eliminates carbon brushes, enabling the BL™ Motor to run cooler and more efficiently for longer life
• Variable speed control dial allows manual RPM adjustment (3,000-8,500) to match the speed to the application
• Paddle switch with no lock-on for operator convenience
• Soft start suppresses start-up reaction for smooth start-ups and longer gear life
• Anti-restart protection engineered to prevent motor start up when battery is inserted with the paddle switch in the on position
• 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
• 3-stage L.E.D. 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 motor
• Extreme Protection Technology (XPT™) is engineered for improved dust and water resistance for operation in harsh conditions
• Rubberized soft grip provides increased comfort on the job
• Compact and ergonomic design at only 15" long
