The DH45MEY 1-3/4 In. SDS max Brushless rotary hammer is the newest rotary hammer in the Metabo HPT lineup. It is constructed with the new AHB (aluminum housing body) construction that provides significant durability and extended tool life. (UVP) (user vibration protection) technology provides vibration protection by first utilizing a polymer coated vibration absorbing handle, then lessening vibration even more with the use of an internal counter balance. The Brushless motor provides a no-maintenance tool so you don't have to stop working to perform routine carbon brush changes. Brushless technology also allows you to run the tool on a portable generator and not worry about work being slowed by voltage drop under loads. The DH45MEY should be the next tool in your jobsite arsenal. Features: IMPACT: 9.9 ft-lbs of impact energy for busting through hard material MOTOR: 1500 watts of input power for increased productivity LOW VIBRATION: UVP (User Vibration Protection) technology greatly reduces vibration for comfortable extended use and fewer vibration related injuries via the use of internal counterweights and springs, as well as low vibration handles BODY: AHB (Aluminum Housing Body) construction significantly enhances the internal and external durability of the tool BRUSHLESS: Ultra efficient AC Brushless motor that permits the use of extra-long extension cords with reduced power loss, extends product life and eliminates maintenance of armatures or carbon brushes IMPACT RATE: 2,500 Full load max impact rate to quickly remove stubborn material CHANGE LEVER: Located on top of tool for easy access - rotates for hammer drilling or hammer only with a neutral position for transitions CLUTCH: Needle pin slip clutch disengages the gears immediately if a bit binds (such as on rebar) to prevent the tool from whipping around CONSTANT SPEED: Control increases power to the tool when under load to keep speed constant for smooth drilling ACCEPTS: Fits popular SDS Max bits
