Bosch GBH 5-40 DCE rotary hammer 0611264000

Power and Performance in Tough Conditions

A tool with 1150 W power and 8.8 J impact energy is a proposal for those who need to drill holes up to 40 mm in diameter in concrete or perform precise chiseling work. Thanks to a motor equipped with the Constant Electronic system, the rotational speed remains constant even under heavy load, which translates to faster drilling progress and reduced material wear. The impact mechanism generates up to 3050 impacts per minute, enabling efficient material removal in hard substrates. It is worth noting that the device is designed for use with core bits up to 90 mm in diameter, making it a versatile tool for plumbing or electrical installation work.

Work Comfort and Operator Safety

Working with heavy equipment doesn't have to mean rapid hand fatigue. This model features the Vibration Control system, which reduces vibrations transmitted to the operator's hands – during drilling, this value is approximately 10 m/s², and during chiseling it drops to 7.5 m/s². This construction allows for longer work without the need for frequent breaks. An additional advantage is the SDS max chuck, which enables quick one-handed tool changes and a switch lock that facilitates prolonged chiseling without continuously holding the trigger. The cable with a ball joint attachment protects against accidental disconnection during sudden jerks.

Construction Durability and Application Range

Solid construction based on metal components and an optimized lubrication system ensure the longevity of the device even with intensive use on construction sites. The tool is intended for professional applications in concrete, stone, and masonry. The set includes an additional adjustable handle, a grease tube necessary for mechanism maintenance, and a sturdy transport case protecting the equipment during transport.

With adjustable rotational speed (165–330 RPM) and impact rate (1500–2980/min), the user can precisely match the working parameters to the specific material, avoiding drill bit damage or excessive dust. This is an ideal solution for installers needing reliable equipment for daily mounting and renovation tasks:

• Mounting hole drilling: performed with hammer drill bits up to 40 mm in diameter.
• Installation work: handling core bits allowing for holes up to 90 mm in diameter.
• Penetrating through partitions: effective drilling with core drill bits in the range of 45 to 55 mm.
• Precise chiseling: performed using appropriate flat and grooving chisels in concrete and stone.
