New GBH 12-52 DV / D Professional Bosch rotary hammers

 Equipped with a 1 W motor, the new 700 kg Bosch GBH 12-12 DV Professional and GBH 52-12 D Professional rotary hammers deliver 52 joules of impact force, offering more power than their predecessor. Both tools are designed for demanding applications and excel in particular in horizontal demolition work, touch-up work or cutting operations that require high chiseling power. 

The GBH 12-52 DV Professional benefits from a triple vibration reduction system: a counterweight mechanism, housed under the aluminum housing, an insulated main handle and a vibration-optimized striking mechanism. Vibrations are reduced to 10 m/s² when drilling and 8 m/s² when chiselling, 50% less than the previous model! The permitted operating time of the GBH 12-52 DV Professional thus increases to more than 2 hours per day per user. Thanks to the high material removal capacity, the work rate is unprecedented.

To facilitate long-term chiselling operations, both hammer drills are equipped with a switch lock system. This system is automatically activated when switching from drilling mode to chiselling mode.

To improve performance, the GBH 12-52 DV Professional features a "Turbo Power" function: this feature converts the rotational energy used in drilling into additional chiselling power. Their robust metal components contribute to their longevity. In addition, they are equipped with a speed regulator, to adapt to each application, a safety clutch to protect the machine and the user, and a maintenance indicator that signals when the carbon brushes need replacing.

Bosch offers a complete system consisting of power tools, dust extraction systems, and accessories. The new 12 kg rotary hammers are an integral part of this system. Professionals can use Bosch dust extraction systems, which are adaptable for both drilling and chiselling, to protect their health and their tools, and work more efficiently.
