Martello perforatore Bosch GBH 18V-22 PROFESSIONAL

The Bosch GBH 18V-22 PROFESSIONAL SDS Plus is a cordless perforator designed for drilling and light chiselling in masonry and concrete. Powered by an 18 V Lithium‑Ion battery system and supplied with two batteries, the tool combines impact energy and compact dimensions to support extended on-site work. With a maximum drilling diameter in concrete of 2.2 cm and an impact energy of 1.9 J, the perforator targets jobs that require reliable percussion performance while remaining easy to handle thanks to a 2.3 kg weight and a compact 102 mm width and 296 mm depth.

Advantages

The tool offers cordless mobility on an 18 V platform, enabling use where mains power is unavailable or inconvenient. Its SDS Plus chuck provides fast bit changes and secure retention. The specified impact energy of 1.9 J and a maximum no‑load speed of 1050 RPM deliver the percussive force and rotational control needed for drilling into concrete up to 22 mm in diameter. Lightweight construction and compact dimensions reduce operator fatigue and improve access in confined spaces. Two included batteries extend runtime and reduce interruptions for recharging.

Suitable for (tasks / use cases)

• Drilling holes in concrete and masonry for anchors and dowels
• Installing fixtures where moderate hammer‑drilling power is required
• Working in confined or elevated locations where a compact, lightweight tool is preferred
• Tradespeople needing portable percussion drilling on sites without immediate power supply

How to use

Fit an appropriate SDS Plus drill bit for the intended hole diameter and secure the battery before operation. Select the drilling or hammer‑drilling mode as required by the material, apply steady pressure, and start at low speed to position the bit. Increase speed and maintain consistent pressure during drilling, allowing the tool's percussive action to advance the hole. For chiselling tasks switch to the chisel position and orient the tool as needed. After use, switch off the tool, remove the battery for safe storage, and clean the chuck and ventilation slots to maintain performance.

Recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and dust extraction or a dust mask when drilling concrete. Match drill bit type and size to the task to avoid overloading the tool. For continuous heavy use, allow batteries to cool between charges and rotate batteries to maintain working time.
