Bosch is now replacing the GBH 18 V-LI cordless rotary hammer with a powerful tool that has a chisel function: the GBH 18 V-EC Professional. It is the first tool from Bosch to be equipped with the new 4.0 Ah battery gen¬eration. The tool therefore has an approximately 35 percent longer runtime than its predecessor.
The best power-to-weight ratio in its classThe GBH 18 V-EC Professional retains the advantages of the previous model in terms of weight and compact design. Just like its predecessor, it offers professional tradespeople the best ratio of power to weight of all cordless rotary hammers in the 18 volt class available on the market. It weighs only 2.6 kilograms and achieves a single impact energy of 1.7 joules. The efficiency of this rotary hammer is especially impressive due to the carbon-brush-free Bosch EC motor with an 80 percent degree of efficiency. Conventional DC electric motors achieve only 60 to 70 percent. Furthermore the motor is dustproof, durable, completely maintenance-free and extremely compact. The tool’s features also include an integrated LED light and a charge level indicator.
The robustness and longevity of the GBH 18 V-EC Professional will benefit professionals in harsh construction site conditions such as; electricians, air conditioning fitters and drywallers. The cordless rotary hammer remains fully functional even after falling from a height of two meters. Another advantage is its compact design which makes it easier to work in hard-to-reach areas or overhead. The optimum application range of the GBH 18 V-EC Professional is at drilling diameters of four to ten millimeters in concrete.
Premium batteries with long lifetimeThe long lifetime of the Bosch Premium batteries used is thanks to the Electronic Cell Protection (ECP). It reliably protects the battery against overload, overheating and deep discharge. Bosch supplies the GBH 18 V-EC Professional cordless rotary hammer with a 45-minute quick charger as standard. Due to the “Hyper Charge” technology from Bosch, the batteries are charged to 75 percent after only half of the charge time. There is also no memory effect and the batteries are fully ready for use, even if they have not been used for months.
The Bosch GBH 18 V-EC Professional will be available from September 2012 onwards in the L-Boxx including two 4.0 Ah batteries and a quick charger at the recommended retail price of 499 euros plus VAT.
