BOSCH GBH 4-32 DFR Professional Rotary Hammer

The BOSCH GBH 4-32 DFR Professional Rotary Hammer is a mains-powered drill for concrete, masonry, stone, wood and metal. Its 900 W motor supports drilling and chiselling during renovation, installation and construction work. Maximum drilling diameter is 32 mm in wood, 13 mm in steel and 32 mm in concrete. These capacities cover general material drilling and larger concrete boring within the stated limits. Unlike a cordless drill, it requires access to an AC mains supply during operation.

At 4.7 kg, the rotary hammer's weight is a consideration for prolonged or overhead work. The SDS Plus holder accepts compatible drill and chisel accessories, while the supplied chuck adapter accommodates additional bit types. Adjustable speed provides control across different materials and accessory sizes. A soft-grip surface and vibration reduction are included to improve handling during extended work. The package also contains an auxiliary handle, depth gauge and carrying case for setup, depth control and transport.
