Maximum drilling and chiselling performance in their class with the 12 kg Bosch GBH 12-52 DV Professional and the GBH 12-52 D Professional rotary hammers. Both tools are driven by 1700 W motors and give a single blow energy of 19 Joules. They offer a significantly higher power output than previous models. The new hammer drills are perfect for e.g. piercing, horizontal dismantling and modification work that requires high penetration rate. The GBH 12-52 DV Professional is also equipped with three levels of vibration damping: The vibration damper integrated into the aluminium cover, the separated main handle and the vibrationresistant hammer mechanism reduce vibrations by up to 10 m/s² when drilling and 8 m/s² when chiselling, which is 50 % less than with the previous model. This means that the GBH 12-52 DV Professional can be operated for more than two hours per day by one person. Combined with high surface removal performance, this results in a noticeable increase in efficiency.
Bosch GBH 12-52 DV Professional and GBH 12-52 D Professional rotary hammers
– More power throughput with 1,700 W motor and 19 Joules single-impact energy
– Two new models with and without vibration damping DV/D
– Low vibration levels enable long periods of work
Easy drilling, long service life
Simple continuous drilling in both models with locking safety switch. It activates automatically when changing from drilling mode to chiselling mode. The GBH 12-52 DV Professional has a Turbo Power function for optimum performance: it converts the energy for the rotary motion during drilling into additional energy for chiselling. That enables professionals to e.g. efficiently drill through cable ducts or chisel openings for windows and doors.
Both models are suitable for demanding surface finishing tasks. Sturdy metal components guarantee a long service life. Additional equipment on the drills include an electronic constant output function for constant performance and a display that shows when the carbon brushes need changing.
