The Bosch GSH 27 VC Professional:

Brand new to our range, the Bosch GSH 27 is "The world’s most powerful electric breaker."

The new GSH 27 is the ideal hammer for the toughest applications: a newly developed hammer mechanism increases the material removal rate per hour by 50% compared to the predecessor model. Very low vibration of only 8 m/s2 enables a trigger time of over 3 hours per working day. For you, this means fast work progress and more comfortable working.
