Perforator Bosch GBH 18V-22 PROFESSIONAL

The Bosch GBH 18V-22 PROFESSIONAL SDS Plus cordless perforator is a compact, battery-powered rotary hammer designed for drilling and light chiselling in concrete, masonry and other common building materials. With an 18 V Lithium-Ion power source and two batteries included, it combines portability with sustained runtime. The tool delivers an idle speed up to 1050 RPM and impact energy of 1.9 J, allowing efficient drilling up to a maximum diameter of 22 mm in concrete while remaining lightweight at approximately 2.3 kg.

Advantages

The perforator offers a balance of power and mobility thanks to its 18 V battery platform and included spare battery for extended work periods. Its 1.9 J impact energy and SDS Plus chuck ensure reliable percussion performance and fast bit changes. A relatively high idle speed of 1050 RPM enables steady drilling progress, while the compact, lightweight construction reduces user fatigue during overhead or prolonged tasks. The cordless design eliminates the need for a power cable and simplifies work in confined or remote locations.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry up to 22 mm
• Installing electrical boxes, conduits and plumbing through walls
• Light chiselling and demolition of tiles, plaster or thin sections of masonry
• Interior renovation tasks where mobility and quick setup are required

Key specifications

• Power supply: 18 V Lithium-Ion battery
• Maximum drilling diameter in concrete: 22 mm
• Idle speed (no-load): 1050 RPM
• Impact energy: 1.9 J
• Chuck type: SDS Plus
• Weight: approximately 2.3 kg (tool only)
• Batteries included: 2 (for extended runtime)

How to use

Fit an appropriate SDS Plus drill bit or chisel and ensure the battery is fully charged before starting work. Select the correct mode for drilling or chiselling if the tool offers multiple modes, and set the bit into the chuck until it locks. Hold the tool with both hands, apply steady pressure and start at low speed to establish the hole, then increase speed as needed. Withdraw the bit periodically to clear dust from the hole. For chiselling, use controlled guided movements and allow the impact energy to perform the work rather than forcing the tool.

Usage recommendations

Use suitable personal protective equipment such as safety glasses, hearing protection and dust mask when drilling concrete or masonry. Choose SDS Plus bits rated for the material and diameter you need. Maintain batteries according to manufacturer instructions and keep spare charged batteries available for uninterrupted work. For larger diameter holes or continuous heavy-duty demolition, consider using a tool with higher impact energy or corded power.
