The Bosch PBH 2500 RE rotary hammer is a power tool for drilling in masonry, concrete and stone. The device is equipped with an impact mechanism. When the percussion mechanism is switched off, the PBH 2500 RE can be used like a drill. However, if the rotation mechanism is switched off, the tool becomes an impact drill. The speed and impact force can be adjusted electronically to optimise the selected material. Bosch rotary hammers are genuine multifunctional tools: hammering, drilling and chiselling are combined in one device. Thanks to their pneumatic impact mechanism, they are not only in their element when drilling in masonry, but also when constructing and assembling solid timber structures such as carports or garden sheds.
