Demolition Hammer Dedra DED7850 1500W 5.5J

The Demolition Hammer Dedra DED7850 1500W 5.5J is a corded electric tool designed for medium-duty breaking and chiselling tasks in construction and renovation. It combines a 1500 W motor with a 5.5 J impact energy to deliver reliable percussive force for removing tiles, breaking concrete, chipping masonry and similar materials. The tool features a rotary hammer mechanism optimized for continuous impact performance and is suitable for workshop and on-site use where a powerful, mains-powered breaker is required.

Advantages

The tool's 1500 W motor ensures consistent power delivery during prolonged operation, while the 5.5 J impact energy balances breaking performance with manageable recoil. The ergonomic handle design and auxiliary grip provide improved control and reduced operator fatigue. The build includes durable components intended for repeated use on hard materials, and the corded power supply eliminates downtime associated with battery charging.

Suitable for

• Removing ceramic tiles and adhesive layers
• Chiselling and breaking concrete and reinforced concrete surfaces
• Demolition of masonry and plaster removal

How to use

Before use, inspect the work area and secure a stable standing position. Fit a suitable chisel or point bit into the tool's holder according to the manufacturer's guidance and ensure it is locked in place. Connect the demolition hammer to a properly grounded mains outlet and set the working mode if the tool provides selectable functions. Position the chisel on the work surface, start the tool, and apply steady pressure while allowing the hammer action to do the cutting or breaking. Do not force the tool; use controlled motion and let the impact energy remove material. Periodically stop to clear debris and check the bit condition.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection, gloves and dust mask. For extended tasks, take regular breaks to avoid overheating the tool and reduce user fatigue. Select chisel types suited to the material and task—flat chisels for surface removal and pointed bits for focused breaking. Ensure power supply and extension cables are rated for the tool's power and kept clear of the working area.
