Bosch Professional GBH 8-45 D SDS Max Rotary Hammer

The Bosch Professional GBH 8-45 D SDS Max rotary hammer is a corded heavy-duty tool for drilling and material removal. Its 1,500 W motor delivers up to 12.5 J of impact energy, supporting repeated hammer drilling in dense masonry. The tool is specified for concrete, stone, brick and masonry work in professional construction and renovation settings. Maximum hammer-drilling capacity in concrete is 45 mm. A separate chiselling mode covers chasing, medium-duty demolition and other material-removal tasks.

The SDS Max chuck accepts compatible drilling and chiselling accessories through a common mounting system. This format is intended for SDS Max attachments rather than standard straight-shank drill bits. An auxiliary handle provides an additional holding point when drilling or chiselling. At 8.2 kg, the rotary hammer has a substantial form factor suited to supported, two-handed operation. The included carrying case provides dedicated storage and makes it easier to transport the tool between work locations.
