Bosch GBH 18V-36 C Professional 500 RPM SDS Max 5.1 kg Black, Blue

The Bosch GBH 18V-36 C Professional is a cordless perforator designed for professional users who need high impact performance without a power cable. Equipped with a brushless motor, this rotary hammer delivers an idle speed up to 500 RPM and an impact rate of 2,900 bpm. The tool uses an SDS Max chuck for quick, tool-free bit changes and is capable of drilling up to 3.5 cm in concrete. Powered by an 18 V, 5.5 Ah battery and supplied with two batteries, the unit balances runtime and mobility while maintaining a pistol-grip design for improved handling. The tool's construction and weight of 5.1 kg support sustained heavy-duty applications on job sites.

Advantages

The brushless motor provides consistent performance and reduced maintenance compared with brushed variants. The SDS Max chuck simplifies bit changes and supports a wide range of demolition and drilling accessories compatible with SDS Max tooling. A high impact rate of 2,900 bpm combined with a maximum idle speed of 500 RPM enables efficient material removal in concrete and masonry. Dual 5.5 Ah batteries increase available runtime, reducing downtime for charging. The pistol-grip configuration and a 5.1 kg weight are intended to improve operator control during extended use.

• Drilling and chiselling in concrete and masonry up to 3.5 cm diameter
• Light demolition and removal of tiles, mortar or surface material
• Site work where cordless mobility and continuous runtime are required

How to use

Install a charged 18 V, 5.5 Ah battery and secure it in the battery compartment until it clicks. Select an appropriate SDS Max bit for the material and task, insert it into the chuck and engage until it locks. Choose the required operating mode and set the tool to the correct rotation and impact settings according to the material and bit diameter. During operation, hold the perforator with a firm two-handed grip using the pistol grip and any auxiliary handle provided, maintain steady pressure without forcing the tool, and allow the impact mechanism to do the work. Replace batteries as needed to maintain performance; follow manufacturer guidance for charging and battery care.

Recommendations

Use the GBH 18V-36 C Professional with SDS Max bits rated for the targeted material. Wear appropriate personal protective equipment, including eye, ear and respiratory protection, when drilling or chiselling concrete. Monitor battery charge levels and carry a spare battery to reduce interruptions on site. For prolonged use, take regular breaks to avoid operator fatigue and check the tool and bits for wear before each shift.
