Leader in its category in terms of performance thanks to the high drilling speed 3 modes of use: Drilling, Drilling with percussion, Percussion (Chiselling) Perform & Protect: the lowest level of triaxial vibrations on the hand-arm system: 10.0m / s², improve comfort of use. Information Leader in its category in terms of performance thanks to the high drilling speed 3 modes of use: Drilling, Drilling with percussion, Percussion (Chiselling) Perform & Protect: the lowest level of triaxial vibrations on the hand-arm system: 10.0m / s², improve comfort in use Mechanical friction reduces kickback in case of tip stall Compact, lightweight and ergonomic design for improved comfort in prolonged use Ideal for anchoring and fixing applications in masonry and concrete. Drilling capacity from 4 to 30mmPerform & Protect: possibility of connection to the D25304DH dust extraction system (sold separately), reduces dust in the working environment TECHNICAL DATA SDS-Plus connectionPower absorbed 950 WattVoltage 0 VPower output - Watt Shot energy (EPTA 05/2009) 3.5 J No-load speed 0-1150 RpmPercussions per minute 0-5200 -Max. drilling capacity [Concrete] 30 mmMax. drilling capacity [Crown] 65 mmMax. drilling capacity - [Wood] 30 mmMax. drilling capacity - [Metal] 13 mm Weight 3.9 Kg Weight (battery included) - g Length 375 mm Height 250 mm Width 95 mm Hand / arm vibrations - drilling into concrete 6.9 m / s² Uncertainty (Vibrations) 1.5 m / s² Hand / arm vibrations - Chiselling 7.8 m / s² Uncertainty ( vibrations) 1.5 m / s² Hand / arm vibrations - Drilling into metal <2.5 m / s² Uncertainty K3 (Vibrations) 1.5 m / s² Hand / arm vibrations - Screw fastening <2.5 m / s² Uncertainty K4 (Vibrations) 1.5 m / s² Acoustic pressure 93 dB (A) Uncertainty (Sound power) 3 dB (A) Acoustic power 104 dB (A) Uncertainty (Sound power) 3 nd Battery 0 Battery 0 Battery 0 Battery 0 Battery capacity 0 Ah Battery capacity 0 Ah
