Hamerboor Bosch GBH 18V-28 CF PROFESSIONAL

The Bosch GBH 18V-28 CF PROFESSIONAL is a battery-powered SDS Plus perforator designed for drilling and light chiselling in concrete and masonry. Equipped with a brushless motor and supplied with two 18 V batteries, it balances high impact performance with a compact, lightweight design. The tool delivers an impact energy of 3.3 J and an impact rate up to 4220 bpm, enabling efficient drilling to a maximum diameter of 28 mm in concrete while remaining portable for site work.

Advantages

The brushless motor increases efficiency and reduces maintenance compared with brushed alternatives, while the cordless design provides freedom of movement on job sites without power cords. With an 8 Ah battery capacity included in the kit, runtime is extended for longer continuous use. Small physical dimensions and a weight of 3.4 kg improve handling and reduce operator fatigue during extended tasks. The SDS Plus chuck ensures quick bit changes and secure bit retention for repetitive drilling and chiselling operations.

Suitable for

• Drilling holes in concrete and masonry for anchors and dowels
• Light demolition and chiselling work such as removing tiles or mortar
• On-site work where portability and battery operation are required
• Repetitive drilling tasks in construction and renovation projects

How to use

Select a suitable SDS Plus drill bit or chisel and insert it into the chuck until it locks. Set the operating mode according to the task (rotary hammer drilling or chiselling) and adjust speed if the tool provides variable control. Position the tool perpendicular to the work surface, apply steady pressure without forcing the tool, and allow the impact mechanism to do the work. For successive holes, withdraw periodically to clear debris; for chiselling, employ controlled strokes and secure the workpiece if necessary. Recharge or swap the included 18 V batteries as runtime decreases.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask when drilling or chiselling. Match drill bit type and size to the material, and follow manufacturer guidance for battery charging and storage to maintain performance and battery life.
