Martelo perfurador Bosch GBH 18V-22 PROFESSIONAL

The Bosch GBH 18V-22 PROFESSIONAL SDS Plus perforator is a cordless rotary hammer designed for drilling and light chiselling in concrete, masonry and other construction materials. Operating from an 18 V battery, it delivers reliable performance with a maximum drilling diameter in concrete of 22 mm. Its compact dimensions and moderate weight make it suitable for confined workspaces and overhead use while providing the impact energy and speed required for routine professional tasks.

Advantages

The tool combines cordless mobility with a focused impact mechanism that produces 1.9 J of impact energy, enabling efficient chip removal and steady penetration in masonry and concrete. With a maximum no-load speed of 1,050 rpm it allows controlled drilling progress and cleaner holes. Its compact form (approximately 102 mm width and 296 mm depth) and a weight of 2.3 kg improve handling and reduce operator fatigue during extended use.

Suitable for

• Drilling holes in concrete and masonry up to 22 mm diameter
• Fixing work such as installing anchors, dowels and conduit
• Light chiselling and removing small sections of plaster or mortar
• Work in confined spaces and overhead applications

How to use

Choose an appropriate SDS Plus drill bit for the material and required hole diameter. Secure the battery and ensure it is charged according to the battery manufacturer's instructions. Select the drilling mode required (rotary hammer/drill or hammer-only if available) and position the bit on the marked drilling point. Start drilling at low speed to establish the hole, then increase speed as needed while maintaining steady pressure—avoid forcing the tool. For repetitive anchoring tasks, periodically withdraw the bit to clear dust and debris for more efficient progression. When chiselling or removing material, use the correct chisel accessory and work with controlled, even strokes.

Recommendations

To extend tool life and maintain performance, use recommended SDS Plus accessories, keep vents and moving parts free from dust, and follow battery care guidelines such as avoiding full deep discharges and storing batteries in a cool, dry place. Wear appropriate personal protective equipment: eye protection, hearing protection and dust mask when working with concrete or masonry.
