Bosch GBH 3-28 DFR 800W 3 Mode SDS Drill (Quick Change Chuck)

At the place of origin: the impact mechanism - A longer air cushion leads to lower pressures and thus lower vibrations (comparable to a longer spring) without reducing performanceAt the place of its effect: the handle - The external shock absorbers further reduce the vibrations. The flat springs separate the handle from the machine

Low vibration (only 12 m/s²) for more comfortable working due to Bosch Vibration Control
Quick-change chuck for fast changes between drilling with impact in concrete and drilling without impact in wood and metal
Balanced weight distribution due to L-shaped design for more comfortable working
Rotation stop for chiselling
Ball grommet for preventing cable breaks
Rotating brush plate for equal power in forward and reverse rotation
Impact stop for drilling in wood and metal
