press release

When using rotary hammers, the most important thing for professionals is the power. With its GBH 8-45 DV Professional eight-kilo rotary hammer, Bosch now offers an exceptionally powerful tool that is also low in vibra­tion. It is powered by a 1500 watt motor and works with an impact energy of 12.5 joules. This enables, for example, breakthroughs to be drilled quickly in walls or ceilings. The “Turbo Power” function of the GBH 8-45 DV Professional ensures optimized performance in chiseling mode because it uses the energy required for the rotation in drilling mode. This increases chiseling performance and enables cable ducts to be cut or floor tiles to be removed extremely quickly.

Long operating duration and high level of comfort
Due to its triple vibration damping, the GBH 8-45 DV Professional has a permitted operating time of more than three hours per day. This damping system consists of a mass damper integrated into the aluminum cap, a de­coupled main handle and a vibration-optimized hammer mechanism. As a result of these features, the rotary hammer achieves low vibration levels of 7 m/s2 when chiseling and 8 m/s2 when drilling. Moreover, a high level of comfort is ensured in continuous chiseling applications by the combination of decoupled main handle and switch lock, which automatically engages when you switch from hammer drilling to chiseling mode. This combination is unique on the market.

The GBH 8-45 DV Professional rotary hammer has a long lifetime thanks to its robust metal components. The integrated overload clutch protects the user and the machine. Other features include a soft start function for clean drilling starts, a speed controller for optimum adaptation to different ap­plications, and a rotation stop for chiseling work.

Bosch also offers matching accessories: “RTec Sharp” SDS-max flat chisels and “RTec Speed” pointed chisels are especially suitable for chiseling with the GBH 8-45 DV Professional. They have a self-sharpening cutting edge, which enables them to achieve a constantly high material removal rate over their entire lifetime. When it comes to drilling in concrete, the “SpeedX” hammer drill bit offers an exceptionally high drilling speed and also has a very long life.

The GBH 8-45 DV Professional will be available at specialist retail outlets from April 2012 onwards for 999 euros plus VAT. It is supplied in a carrying case that has a lot of space for accessories.

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). The company generated sales of 70.6 billion euros in 2015. Its operations are divided into four business sectors: Mobility Solutions, Industrial Technology, Consumer Goods, and Energy and Building Technology. The Bosch Group comprises Robert Bosch GmbH and its roughly 440 subsidiaries and regional companies in some 60 countries. Including sales and service partners, Bosch’s global manufacturing and sales network covers some 150 countries. The basis for the company’s future growth is its innovative strength. Bosch employs 55,800 associates in research and development at 118 locations across the globe. The Bosch Group’s strategic objective is to deliver innovations for a connected life.
