The XAG12 is a 36V Brushless paddle switch angle grinder equipped with an electric break to maximize productivity. Powered by 2 -18V batteries for 36V performance, this means freedom from the cord. The electronically controlled motor matches torque and RPM to the application, and can also turn the motor off is rotation speed suddenly slows or stops.  
 
The BL™ Brushless Motor eliminates carbon brushes, enabling the BL™ Motor to run cooler and more efficiently for longer life; delivers 7,800 RPM
Two 18V LXT® Lithium-Ion batteries deliver corded power without leaving the 18V LXT® battery platform
Electric brake stops the grinding or cut-off wheel in 4.5 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
Vibration absorbing back handle is isolated from the motor housing effectively reducing vibration to the operator's hands
Rear handle paddle switch with no lock-on feature
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
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 switch locked on
Weighs only 11.4 lbs. with battery for reduced operator fatigue
Rubberized soft grip handle provides increased comfort on the job
