Bosch 0 611 320 703 rotary hammer 650 W

The Bosch 0 611 320 703 rotary hammer is a corded power tool engineered for drilling and light chiselling in masonry, concrete and stone. It is powered by a 650 W motor delivering up to 2.6 J impact energy at an impact rate of 3,500 blows per minute, combining steady rotation with percussive force for efficient penetration. The tool’s compact footprint—89 mm wide, 376 mm deep and 208 mm high—and a working weight of 3.5 kg provide a balance between manoeuvrability and stability for extended use.

Advantages

The 650 W motor offers consistent torque under load while the 2.6 J impact energy and high impact rate enable fast drilling progress in concrete and masonry. Compact dimensions and a moderate weight reduce operator fatigue and improve access in confined spaces. Built for durability and continuous AC operation, the design focuses on reliable performance for repetitive tasks. Measured vibration data for concrete work includes an uncertainty coefficient of 1.5 m/s², supporting informed handling and safety planning.

How to use

Select the appropriate drill bit or chisel for the material and secure it in the chuck according to the tool’s instructions. Connect the rotary hammer to a suitable AC power outlet and set the required mode (drilling or hammer drilling) before starting work. Apply steady forward pressure without forcing; let the tool’s impact energy and rotation do the cutting. For chiselling, use controlled, even movements and reposition frequently to avoid overheating the bit and the motor.

Recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when working in masonry or concrete. Select correct drill sizes and anchors for the intended fixings, and allow short pauses during long continuous operation to prevent overheating. For prolonged overhead or confined-space work consider job rotation or auxiliary handles to maintain control and reduce fatigue.
