Bontókalapács Makita HM0871C

The Demolition Hammer Makita HM0871C is a heavy-duty SDS‑MAX jackhammer designed for professional demolition and chiselling tasks. It is powered by an 1100 W motor that produces up to 8.1 J of impact energy and an impact rate of 2650 blows per minute. With compact external dimensions and a balanced form factor, this demolition hammer combines high performance with manageable handling for extended use on construction sites and renovation projects.

Advantages

The tool offers high durability and sustained demolition performance thanks to a robust motor and reinforced housing. Anti‑vibration technology reduces vibration transmission to the user, registering a vibration level of 8 m/s² during chiselling to increase comfort during prolonged operation. Variable speed and constant speed under load deliver consistent results across different materials, while soft start improves control at startup. One‑touch sliding chuck simplifies SDS‑MAX bit installation and removal. An LED lamp notifies when carbon brushes need replacement, and double insulation enhances electrical safety.

Suitable for

• Breaking concrete, masonry and reinforced structures
• Removing tiles, screed and flooring layers
• Preparing openings for plumbing and electrical installations
• Heavy chiselling and light demolition work on construction sites

How to use

Select an appropriate SDS‑MAX chisel for the task and ensure the bit is clean and undamaged before installation. Fit the bit using the one‑touch sliding chuck and confirm it is securely engaged. Use the variable speed control to match impact frequency to material hardness, and allow the soft start to stabilize operation. Maintain a steady stance and grip the tool with both hands, letting the hammer do the work rather than forcing it. Monitor the LED lamp for carbon brush replacement indication and switch off the tool before performing maintenance or changing bits.

Recommendations

For optimal performance and longevity, use appropriate personal protective equipment, including hearing protection, eye protection and dust mask. When breaking reinforced concrete or working for extended periods, schedule regular breaks to reduce operator fatigue and inspect the tool periodically for wear on the chuck, brushes and power cord. Store the demolition hammer dry and clean to prevent corrosion and preserve insulation properties.
