Description

Bosch GBH 3-28 DFR 3kg SDS+ Rotary Hammer Drill with Quick Change Chuck

FEATURES

  • High drilling rate and 20% higher chiselling power than other rotary hammers in its class
  • 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

VIBRATION CONTROL

  • 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 performance
  • At the place of its effect: the handle – The external shock absorbers further reduce the vibrations. The flat springs separate the handle from the machine
