Perforator Bosch GBH 12-52 D Professional

The Bosch GBH 12-52 D Professional is a heavy-duty perforator designed for demanding drilling and chiselling tasks in concrete and masonry. Equipped with a 1700 W motor and an SDS Max chuck, this rotary hammer delivers robust impact performance and reliable bit retention for work at construction sites and in renovation projects. With an impact energy of 19 J and a maximum drilling capacity reaching up to 150 mm in concrete, it handles large-diameter drilling and tough demolition jobs while maintaining stable operation at up to 220 RPM.

Advantages

The tool combines high impact energy with a powerful motor to enable fast progress in hard materials without frequent overload. SDS Max compatibility ensures quick, secure bit changes and broad accessory availability. Despite its rugged construction, the perforator is designed for manageable handling: the weight and balanced dimensions support prolonged use with controlled vibration transfer. Durable build quality and consistent power delivery make it suitable for continuous professional operation.

How to use

Select an appropriate SDS Max drill bit or chisel for the material and required hole diameter. Secure the perforator on a stable surface and check that the bit is fully engaged in the chuck. Set the machine to the drilling or chiselling mode as needed and start at low speed to position the bit, then increase to working speed. Apply steady pressure without forcing the tool; allow the impact mechanism to perform the work. After completing the operation, turn off the tool and wait until the bit stops fully before removing it. Follow all safety guidelines including eye, ear and respiratory protection when working with dust and debris.

Usage recommendations

For optimal performance, use sharp, manufacturer-recommended SDS Max accessories, inspect carbon brushes and power cord regularly, and allow the motor to cool during prolonged heavy-duty use. When drilling large diameters or deep holes, remove debris frequently to maintain efficient impact action and prevent binding.
