Bosch Blue Rotary Hammer Drill GBH 3-28 DFR

Bosch Blue Rotary Hammer Drill GBH 3-28 DFR

This Bosch Rotary Hammer Drill GBH 3-28 DFR Professional, utilizes Bosch’s slotted drive system (SDS). This allows the drill bit to be thrust forward during hammer action, giving you more performance.

Bosch Rotary Hammer Drill GBH 3-28 DFR Professional, is a high-performance electric drill with SDS+. Due to its L-shaped design, it is perfectly balanced with low vibration.

It has many features such as a rotation stop, which allows you to use it as a chisel. With its 800 Watt high drilling rate and 20% higher chiseling performance than other rotary hammer drills, it is one drill that deserves to be in your toolbox.

The rotating brush plate inside gives you equal power in forward and reverse rotation, making drilling simple and accurate.

FEATURES

• High drilling rate and 20% higher chiseling 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 chiseling
• 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
