Bosch GBH 12-52 D Professional SDS Max Rotary Hammer 1700 watt 19 joule

The Bosch GBH 12-52 D Professional SDS Max Rotary Hammer 1700 W 19 J is a mains-powered rotary hammer for professional construction, renovation and installation work. Its rated input power is 1,700 W for drilling and chiselling concrete, masonry and other hard materials. Maximum impact energy reaches 19 J, supporting demanding material removal and large-bore drilling. The stated maximum drilling diameter in concrete is 150 mm, including work with core cutters. Corded operation avoids battery runtime limits but requires access to a mains supply.

At 11.5 kg, the rotary hammer has a substantial form suited to controlled, two-handed operation. Its SDS Max chuck accepts compatible heavy-duty drill bits and chisels. Adjustable speed allows the operating rate to be matched more closely to the material and accessory. A 600 mm body length is relevant when assessing clearance, transport and working space. The supplied carrying case provides dedicated storage between jobs.

• Up to 2,150 impacts per minute for drilling and chiselling in hard materials.
• Maximum no-load speed of 220 RPM.
• Overload clutch is fitted.
• Auxiliary handle is included for two-handed control.
• Depth gauge is included for setting repeat drilling depths.
