Bosch GBH 2-28 F SDS+ Plus Rotary Hammer Drill with Quick Change Chuck in L-boxx

The Bosch GBH 2-28 F Professional rotary hammers are the most innovative in their class. A powerful 880 watt motor and 3.2 joules of impact energy allow for the fastest work rate in their class, for example when chiselling, be it in concrete, stone, steel or wood. The Bosch rotary hammers are versatile to use, and are also suitable for large diameters of up to 68 mm. Reliable Bosch quality ensures robust tools and a long lifetime.

The GBH 2-28 F Professional Hammer Drills are the first rotary hammers in their performance categTopory to be equipped with KickBack Control. This function gives you more control in the toughest drilling applications. If the power tool suddenly and unforeseeably rotates around the drilling axis – such as when the drill bit jams in reinforced concrete – the integrated sensor will shut down the motor within a fraction of a second. This prevents unexpected kick-back of the tool and can therefore reduce the risk of injury. What’s more, both rotary hammers are equipped with active vibration damping: A counter oscillator positioned in the gear housing permanently counteracts the air and mass forces from the hammer mechanism, therefore reducing the vibration levels to 11 m/s². As a result, working with these tools is kinder to your health, less tiring and also more precise.

These 'F' models comes with an additional quick-change keyless chuck for straight shank drill bits.
