FeaturesFastest drilling and chiseling speeds on the market
Best-in-Class impact energy of 11.4 ft-lbs for unmatched performance
11.6 amp, 1200 watt motor increases productivity
IDI (Internal Double Insulation) Technology includes a rigid aluminum housing to protect against jobsite abuse
Constant speed control minimizes changes in speed and hammering as load varies, creating more efficient performance
Electronic variable speed control allows user to select tool speed appropriate for the material with a full-load RPM range of 120-240 and impact rates of 1200-2500 BPM
Auto-stop carbon brushes prolong service life of tool
Needle-pin slip clutch provides higher slip torque accuracy to protect gears and increase user safety
Variable lock mechanism provides optimal working angles with easy bit changes
Two modes of operation- hammer only & hammer-drill- give the user flexibility throughout a range of applications
Elastomer coated handles have a soft grip for more comfortable, non-slip operation
Removeable side handle is securely fastened with a rigid steel bracket and can be adjusted 360 degrees for control and maneuverability
Depth gauge insures accurate drilling depth
Metal seatings for motor bearings prevent motor core deviation and grease leakage that shortens the life of the tool
