Peak chiselling performance is now a given with the new GBH 12-52 D Professional rotary hammer from Bosch. This is thanks to a 1 700 W motor producing 19 J of impact energy, making it the most powerful rotary hammer from Bosch to date.

The improved performance means this rotary hammer is ideal for arduous applications such as removing sturdy floor tiles, concrete breakthroughs, and concrete demolition. “Construction sites are arduous environments that require the most robust tools,” Campbell Mhodi, Bosch Professional Power Tools Senior Brand Manager, comments.

The GBH 12-52 D only weighs 11.5 kg. It has a vibration value of 20 m/s2 when drilling and 15 m/s2 when chiselling. It has a maximum drilling diameter of 52 mm and a 150 mm maximum hole size (with a hollow drill bit). The Vario-Lock features allows users to select the best of 12 positions when chiselling, while the Constant Electronic feature has an absolute speed dial with six positions.

The auto lock-on trigger increases user comfort during continuous chiselling operations. In drilling mode, the switch does not lock on, which is a significant safety feature. In chiselling mode, the switch locks on automatically, and is released manually by pulling the lower trigger.

The rotary hammer is supplied in a handy carrying case, which has ample space for accessories. These include hammer-resistant core cutters for the toughest applications faced by rotary hammers, including the SDS-max holder.

The core cutters feature a sturdy, hardened bit body with spiral flute and a double wave base for an extremely fast drilling rate. In addition, the tungsten carbide teeth of the hammer drill bit guarantee a long life. The GBH 12-52 D is also compatible with the GDE 68 Professional and GDE 162 Professional dust extraction systems for drilling. “We offer a total system comprising professional power tools, dust extraction systems, and accessories,” Mhodi concludes.
