An impulse hammer is a hammer equipped with a piezoelectric force sensor and enables the excitation of a structure under investigation. Different hard tips made of steel, various plastics and rubber of different hardness can be mounted on the force sensor, each of which excites different frequency spectra.
What is an impulse hammer and how does it work?
An impact hammer, also known as an impact drill, is a tool used to drill holes in various materials such as concrete, stone or masonry. In contrast to a normal drill, an impulse hammer also generates a percussive movement in addition to the rotating movement in order to penetrate the material more effectively.
An impulse hammer consists of an electric motor that generates a piston movement. The piston is connected to a hammer mechanism that produces a short, rapid back and forth movement. This movement is transferred to the drill and generates impacts as it rotates. The combined rotary and percussive movement of the drill bit enables it to penetrate the material more easily.
Depending on the model and setting, the impact force of an impact hammer can be adjusted to meet the requirements of the material to be drilled. Some impulse hammers also have a rotary stop function that allows the drill bit to be used as a chisel to remove or remove materials.
It is important to take the right safety precautions when working with an impact hammer, as its high power can lead to vibrations. We recommend wearing safety goggles, hearing protection and work gloves to prevent injuries.

What advantages does an impulse hammer offer compared to other tools?
An impulse hammer offers several advantages compared to other tools:
1. High impact: Impulse hammers generate a high impact force, which enables them to work effectively even on hard materials such as concrete or stone. You can drill deep holes or remove surfaces without having to apply a lot of force.
2. Fast work progress: Thanks to the high impact force and fast impact frequency, the impulse hammer enables rapid work progress. It can remove large quantities of material or drill holes in a short time, which increases the efficiency of the work.
3. Versatility: Impulse hammers are usually compatible with various attachments such as chisels or drill bits. As a result, they are versatile and can be used for various types of work, such as demolition work, stonework or tile removal.
4. Low stress for the user: Compared to other tools such as a normal hammer or a chisel and hammer combination, the impulse hammer is less stressful for the user. The impact force is generated by the motor, which means that the user has to exert less force. This reduces fatigue and allows you to work for longer periods without interruptions.
5. Precision: Impulse hammers often offer good control and precision at work. They are usually equipped with different settings for impact force and impact frequency, which can be adapted to the specific requirements of the task in question. This allows the user to tailor the tool exactly to their needs and achieve precise results.

How strong is the impact force of an impact hammer and how is it measured?
The impact force of an impulse hammer is measured in joules (J) or newton meters (Nm). It indicates how much energy per blow the hammer transfers to the workpiece.
The impact force depends on various factors, such as the power of the motor, the weight of the hammer and the speed of the impact mechanism. The higher the impact force, the more effectively the impulse hammer can process materials.
The exact impact force of an impact hammer can be determined using various measurements. One possibility is to directly measure the kinetic energy of the hammer when it strikes the workpiece. The speed of the hammer and its weight are taken into account. Another method is indirect measurement by determining the force transferred to the workpiece. Sensors or measuring devices are used to record the force of the hammer on impact.
It is important to note that impact force is not the only criterion for the effectiveness of an impact hammer. The impact frequency, the durability of the device and the type of workpiece also play a role. Therefore, when selecting an impact hammer, attention should not only be paid to the impact force, but also to other factors.
