• Features AC Brushless Motor Technology for more run time, increased power and extended durability with essentially no maintenance
• Patented User Vibration Protection (UVP) Technology via internal counterbalance mechanisms and shock absorbing handles significantly reduces full-load tri-axial vibration transfer to the user for less fatigue and more production 
• AHB (Aluminum Housing Body) construction increases the life of the tool by combining a strong aluminum outer housing with a plastic inner housing to reduce vibration and improve safety
• Internal inverter circuit allows the tool to run from generators and long extension cords without the issues of voltage drop
• 2 Modes of operation- hammer drilling & hammer only- for flexibility within a range of applications
• Push button rotation speed selector switch adjusts the impact rate according to the application and can be maintained regardless of load, improving drilling efficiency
• Power indicator lamp lights up when power is supplied to the tool
• 8.1 ft-lbs of impact energy for busting through hard material  
• 2,850 Full load max impact rate to quickly remove stubborn material
• 11.3 Amp motor and 1150 watts of input power for increased productivity
• Optimized striking for more efficient transmission of power        
• Idle strike restrictor to prevent no-load activation and additional wear on the tool
• Dust-resistant structure to guard internal components from harmful debris as well as grease leakage            
• Needle-pin slip clutch to protect tool gears and the safety of the user
• Variable lock mechanism in neutral position for 12-angle positions and a quick release system for simple bit changes
• Soft, non-slip elastomer grip handle for improved comfort and control
• 360 Degree adjustable side handle for maneuverability in tight spaces
• Depth stopper rod for drilling accuracy    
• Accepts popular SDS Max bits
