Bosch GBH 3-28 DFR Rotary Hammer Drill 800 W 3.1 J SDS Plus Black/Blue

The Bosch GBH 3-28 DFR Rotary Hammer Drill is a corded electric power tool designed for masonry, concrete, wood, and steel work. It uses an SDS Plus chuck system to hold compatible bits securely during standard site tasks. The motor draws 800 W from the mains supply and delivers a maximum impact energy of 3.1 J. Operators can switch between standard drilling, hammer drilling, and light chiselling modes depending on the material. Running directly from an AC supply keeps the mechanical output consistent during extended jobs, with no battery to run flat.

Weighing 3.6 kg, the rotary hammer has a soft-grip surface and an adjustable auxiliary handle to keep it under control during use. Variable speed control lets the operator match the rotational pace to the material. A built-in reverse function allows users to back out jammed bits from deep or angled holes. The black and blue housing protects the internal mechanisms and conforms to standard site colour coding. No drill bits are included, but the tool comes with a dedicated carrying case for transport and storage.

• Maximum no-load speed of 900 RPM and a peak impact rate of 4,000 blows per minute.
• 28 mm maximum drilling diameter in concrete, with an optimum performance range of 12 to 18 mm.
• 30 mm maximum drilling capacity in wood and 13 mm in steel.
• Vibration emission levels of 11.8 m/s² for hammer drilling and 10 m/s² for chiselling.
• Overall dimensions of 355 mm wide, 233 mm high, and 85 mm deep for use in restricted spaces.
