press release

80 years after introducing the first electric hammer, Bosch is now launching the GSH 11 VC Professional onto the market. With 1700 watts of power and 23 joules of impact energy, it is the world's most powerful electric breaker in the eleven-kilo class. It also offers the best power-to-weight ratio in this class. This enables professionals to be very mobile and to work efficiently. Moreover, this tool has a special design: the housing of the hammer mechanism is elongated and positioned virtually in the center of the tool. This gives the tool a balanced center of gravity, and the extra centimeters of length make it comfortable to handle when working towards the ground. The GSH 11 VC Professional is just as reliable at completing demolition and correction work in concrete and stone as it is at making breakthroughs for laying pipes, ventilation and cable lines or removing floor tiles. The impact rate can be set from 900 to 1,700 revolutions per minute.

Vibration-damped hammer mechanism for long operating time
The permitted operating time of the GSH 11 VC Professional is more than three hours per day. This is made possible by decoupling of the main and side handles combined with a vibration-optimized hammer mechanism. Thanks to these features, the tool achieves low vibration of 8 m/s2. The average material removal rate is more than one ton of concrete per hour.

The breaker has an SDS-max holder for quick, tool-free accessory changes. It can be used with numerous accessories such as the “RTec Sharp” SDS-max flat chisel and the “RTec Speed” pointed chisel. These chisels have a self-sharpening cutting edge, which enables them to achieve a constantly high material removal rate over their entire lifetime. They are therefore especially suitable for use with the breaker. The “Vario-Lock-System” can be used to lock the chisels in twelve positions to adapt them precisely to each work situation. The features are completed by a service display that indicates when the carbon brushes need to be changed, Constant Electronic for constant power under load, and an on/off switch that can be comfortably operated from the handle at any time.

The GSH 11 VC Professional will be available at specialist retail outlets from September 2012 onwards at the recommended retail price of 929 euros plus VAT. It is supplied in a carrying case including side handle and an “RTec Speed” pointed chisel.

80 years of hammer expertise in trade and industry
In 1932, Bosch produced the first rotary hammer in series. It was com­pletely tailored to the needs of professionals, it had an impact mechanism for drilling and chiseling, and enabled a considerably faster working progress then hand tools used so far. This world first celebrated its premiere 80 years ago at the Leipzig trade fair, setting a milestone in the construction industry. Since 1932, Bosch has continually enhanced the hammer and has often assumed the role of technology leader. Many developments have prevailed as worldwide standards on the market. An example is the SDS-plus toolholder launched in 1975 for fast, tool-free drill bit and chisel changes. This was followed in 1990 by the SDS-max version for larger drill bits and chisels. Further milestones are the world’s first two-kilo rotary hammer (1981), the world's first cordless hammer (1984), the world's first cordless hammer with lithium-ion technology (2005) and the world's first SDS-plus hammer with active vibration damping (2011).

The Power Tools Division of the Bosch Group is one of the world’s leading providers for power tools, power tool accessories and measuring tools. In 2015, its roughly 20,000 associates generated sales of 4.5 billion euros, about 85 percent of which outside of Germany. With brands such as Bosch, Skil and Dremel, the division stands for customer focus and great engineering progress. The core success factors are innovative strength and pace of innovation. The division generated about one third of its sales in 2015 with products that have been on the market for less than two years. In 2016, Bosch Power Tools will again launch more than 100 new products onto the German market in its four business segments power tools, accessories, measuring tools and garden tools.

The Bosch Group is a leading global supplier of technology and services. It employs roughly 375,000 associates worldwide (as of December 31, 2015).
