Bosch GBH 18V-26 D Professional 425 W 890 RPM SDS Plus

The Bosch GBH 18V-26 D Professional is an SDS Plus perforator designed for drilling and light chiselling in concrete and masonry. With a rated power equivalent of 425 W and a maximum drilling diameter in concrete of 26 mm, the tool combines compact dimensions and reduced weight of 2.6 kg to deliver practical handling on construction sites and during renovation work. Battery operation with Lithium‑Ion technology removes the need for mains cables while supporting continuous work cycles and flexible positioning.

Advantages

The perforator offers a balance of power and portability: a high impact performance for its class supports efficient hole drilling in concrete, while a top rotational speed up to 890 RPM speeds up drilling progress. Its compact, lightweight construction and ergonomic grip reduce operator fatigue during extended use. Cordless battery operation improves mobility and allows use in locations without easy access to power outlets. Durable construction and professional-grade components ensure stable performance under frequent use.

How to use

Select the appropriate SDS Plus drill bit and secure it in the chuck according to the manufacturer's instructions. Set the tool to the drilling or hammer-drilling mode depending on the material. When drilling into concrete, start at a low speed to position the bit, then increase to the required speed up to 890 RPM while applying steady pressure. Use short breaks when drilling multiple holes to avoid overheating the bit and battery. For chiselling tasks, switch to the chisel function and maintain control with both hands, keeping the perforator perpendicular to the work surface where possible.

Recommendations

Use compatible Bosch SDS Plus bits and a fully charged Lithium‑Ion battery for best performance. Wear appropriate personal protective equipment including safety goggles, hearing protection and dust mask when working with concrete and masonry. For consistent results, allow the battery to cool between heavy use cycles and store the tool and batteries in a dry, cool place.
