Martillo perforador Bosch GBH 8-45 D Professional

The Bosch GBH 8-45 D Professional is a heavy-duty perforator designed for demanding drilling and chiselling tasks. Equipped with a 1,500 W motor and an impact energy of 12.5 J, it delivers high performance for professional construction work. The tool features an SDS Max chuck for fast bit changes, a rated speed of 305 RPM and can drill up to 45 mm in concrete. With robust components, overload clutch protection and a compact yet solid build, it is intended for continuous use on tough jobs.

Advantages

The perforator provides strong drilling and chiselling performance via its 1,500 W motor and 12.5 J single-impact energy. A soft-start reduces wandering when starting holes, while the automatic switch lock improves user comfort during prolonged chiselling. Durable construction and robust internal components increase service life, and the overload clutch helps protect both the operator and the machine. A variable speed control enables adjustment to suit different materials and applications.

Suitable for

• Drilling large-diameter holes in concrete and masonry (up to 45 mm)
• Chiselling and demolition work on reinforced concrete and stone
• Heavy-duty construction site applications requiring continuous operation
• Professional tradespeople needing reliable SDS Max performance

How to use

Select an SDS Max bit suitable for the material and secure it in the chuck. Set the required speed using the rotation regulator and, if starting a new hole, use the soft-start feature to ensure precise positioning. For prolonged chiselling, engage the automatic switch lock to maintain continuous operation without holding the trigger. Apply steady pressure without forcing the tool; allow the hammer action to perform the work. If resistance increases significantly, stop and check bit condition and settings. Use the overload clutch as intended — it will disengage to protect the tool and user under excessive load.

Recommendations

Use appropriate personal protective equipment (safety goggles, hearing protection, gloves) and secure the workpiece. Match drill bits to the intended material and inspect bits regularly. For extended heavy-duty use, allow the tool to cool periodically and follow Bosch maintenance guidelines to maximise service life.
