Bosch Professional GBH 3-28 DFR SDS+ Plus Rotary Hammer Drill With QCC

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
