Makita 2" SDS MAX Advanced AVT® Rotary Hammer

Powerful 15 AMP motor delivers 14 ft.lbs of impact energy to handle the most demanding applications.  Advanced AVT® includes a vibration absorbing housing with a spring loaded back handle and housing which moves independently of the motor and hammer mechanism effectively isolating more vibration away from the user.  Advanced AVT® includes an integrated damper spring at the base of the impact bolt engineered to absorb impact vibrations from the drill bit.  Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs.  Soft start suppresses start-up reaction for more precision and better accuracy. 2-mode operation for "Chipping Only" or "Hammering with Rotation".  24 bit angle settings allow the bit to be set at different positions for operating convenience.  Includes: depth rod, hammer bit grease, cloth wiping oil, d-handle, straight handle, straight handle assembly, and accessory case.
