Demolition hammers are also known as jackhammers or breakers. They are essential tools in the construction and renovations industry. These power tools are designed to break through concrete, bricks and natural stones. They are commonly used in construction, remodeling and renovation projects. These robust machines generate high-impact force through a piston-driven mechanism, making them ideal for breaking concrete, masonry, and other solid materials. The most common are the 5kg hammer, a good example is the GSH 500. In the 11kg class we have GSH 11. These two have a SDS max bit holder. In the 16kg class we have GSH 16-28, with a 28mm internal hexagon bit holder. The most powerful of them all is GSH 27 VC which is a 30kg hammer. Let’s look at their features;
Power source;
Most demolition hammers are electric as they tackle smaller jobs. For heavy duty demolition works you will find the pneumatic or hydraulic demolition hammers more suitable due to the nature of work.
Impact energy;
The impact energy is a crucial factor in a demolition hammer’s performance. It determines how effectively the tool can break through tough materials. The higher the impact energy, the more powerful the tool.
Vibration control;
Low vibrations causes less fatigue to the operators, making working more comfortable. High vibration can be a major concern when using demolition hammers for extended periods.
Types of chisels used
Chisels come in different categories. There are SDS plus chisels used with small hammer drills, SDS max chisels which are used with the larger hammer drills or 5kg and 11kg demolition hammers. Then we have the hex shank chisels which are mostly used with the 16kg or the 30kg breakers. Some common chisel types include;
Pointed chisels;
These have a sharp pointed tip and are ideal for breaking through concrete, brick or stone. They are excellent for creating starting points or focusing force on a small area.
Flat chisels;
Flat chisels have a flat wide blade and are suitable for chipping away concrete, tile or plaster. They are effective at removing surface layers and providing a smooth finish.
Tile chisels;
Tile chisels have a wide, flat blade with a V-shaped notch. They are specifically designed for removing tiles and thin layers of mortar or grout.
Moil chisel;
Moil chisels have a rounded, conical shape and are useful for breaking up tough concrete or rock. They can penetrate deep into materials, making them versatile tools for demolition.
In conclusion, demolition hammers and chisels are indispensable tools in the construction and renovation industry, allowing for precise and efficient destruction of hard materials. Choosing the right tool and using it correctly is essential for safety and effectiveness. Whether you’re breaking through concrete or removing tiles, these tools are the powerhouse and precision instruments you need to get the job done right.
