This model is a favorite because it’s so user-friendly, weighing in at under 23 pounds and about as many inches in length – practically diminutive next to its competition. Its power, however, is not at all relative to its size, offering a range of impact energy from 4.4 to 18.4 ft./lbs. and up to 1,890 blows per minute, reducing tough concrete to dust. Part of the beauty of this hammer is that it actually doesn’t want you to do the work for it; we found that exerting force on it actually slows you down. Instead, firm, steady pressure got us the best results. We particularly like the design of this hammer; instead of the traditional linear approach, Bosch built it more like a pistol, and that may (or may not, we’re not rocket scientists) be part of why so little vibration is felt. The rear handle is generously padded, and the auxiliary handle rotates 360 degrees so you can set it exactly where you need it. Another check in the ergonomics column comes from the electronic feedback system
