Perforator Bosch GBH 18V-26 F Professional

The Bosch GBH 18V-26 F Professional is a cordless perforator engineered for drilling and light chiselling in concrete, masonry and other common construction materials. Designed for professional use, it combines a compact form factor with a rated speed of 890 RPM and an impact energy of 2.6 J to deliver efficient hole making up to 26 mm diameter in concrete. The tool is powered by an 18 V Lithium-Ion battery, which provides the mobility needed on site while keeping the overall weight to 3.6 kg and maintaining manageable dimensions for overhead and confined-space work.

Advantages

The GBH 18V-26 F Professional offers a balance of power and portability: its 2.6 J impact energy and 890 RPM rated speed enable consistent drilling performance in concrete and masonry. Cordless operation with an 18 V Lithium-Ion battery removes the need for a power cord, improving access to hard-to-reach areas and simplifying transport between job locations. The compact dimensions and 3.6 kg weight reduce user fatigue during prolonged use and make the tool suitable for overhead drilling. Durable construction and a professional-grade gearbox contribute to reliable operation under regular trade use.

Suitable for

• Drilling holes in concrete and masonry up to 26 mm diameter
• Light chiselling and anchor installation in construction sites
• Installation work in confined or elevated spaces where cordless tools are advantageous
• Trade professionals requiring a portable rotary hammer for daily tasks

How to use

Before operation, fit a compatible SDS‑plus bit and ensure the battery is fully charged. Select the appropriate mode for drilling or chiselling if the tool provides mode selection. Position the bit at the intended drilling point, hold the tool with both hands to stabilize it, then start at low speed to establish the hole before applying steady pressure. Allow the tool’s impact mechanism to work without excessive force; apply constant, controlled pressure and withdraw periodically to clear debris from the hole. After use, switch off the tool, remove the battery for storage or charging, and store the perforator in a dry, secure place.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, gloves) and select drill bits rated for concrete. For prolonged tasks, use a fully charged 18 V Lithium‑Ion battery and keep a spare charged battery available to maintain workflow. Regularly inspect the chuck and bits for wear and clean ventilation openings to ensure cooling and long tool life.
