Bosch GBH 18V-34 CF Professional 500 RPM SDS Plus 4.9 kg Black, Blue

The Bosch GBH 18V-34 CF Professional is a cordless perforator designed for trade and on-site work where power and mobility are required. Equipped with a brushless motor and an SDS Plus chuck, this rotary hammer delivers impact drilling performance without the constraints of a power cord. It comes with two 5.5 Ah batteries to support extended operation and quick battery swaps, while a compact design and a total weight of 4.9 kg make it suitable for overhead and prolonged use. Maximum idle speed reaches 500 RPM and the tool can drill into wood up to 40 mm, providing a balance of rotary speed and impact energy for common construction tasks.

Advantages

The brushless motor increases efficiency and reduces maintenance compared with brushed designs, resulting in longer runtime per battery charge. SDS Plus chuck enables fast bit changes and secure retention for hammer drilling and chiselling. Supplied with two batteries, the tool supports uninterrupted work through battery rotation and minimizes downtime. Weighing 4.9 kg, the perforator is engineered for manageable handling in confined spaces and during overhead operations. The fast charging capability of the batteries shortens downtime between shifts.

How to use

Select the appropriate SDS Plus drill bit or chisel for the material and secure it in the chuck until it locks. Choose the required operating mode and speed according to the task; start drilling at low speed to establish the hole and then increase speed as needed. For hammer drilling in masonry or concrete, maintain steady pressure and allow the tool to perform the impact action rather than forcing it. When working in wood, ensure the bit is rated for timber and observe the 40 mm maximum recommended diameter. Swap batteries as needed to maintain continuous operation and follow the battery manufacturer’s instructions for charging and storage.

Recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and gloves. Allow the tool to cool during extended heavy use and inspect drill bits and chisels for wear before use. Store batteries in a dry, cool place and use the supplied charger to preserve battery life and performance.
