  • Item Excavator

  • Impact Energy

    The impact force shows how powerful the tool is. The more Joules, the stronger the hits.

    2. Specifically for demolition tools with frequent and heavy use, at least 20 Joules are recommended.

    6.1

    Tools with at least 5 Joules are recommended for heavy duty work and professional use.

  • Socket

    SDS Max (TE-Y)

    SDS sockets have better performance in rotary hammer functions compared to others and are suitable for working on concrete or stone. They also allow for easy change of drill bits, which can be done with one hand. 2. SDS-Max (TE-Y) sockets have a base diameter of 18 mm and can accept drill bits with diameters between 13-40 mm. These sockets are only compatible with corresponding SDS Max drill bits.

  • Speed Setting

    1

    Ability to control the rotation speed, either through the trigger or via a speed selector.

  • Maximum Number of Impacts

    The number of strikes that the machine can deliver in one minute. Generally, the higher the number, the easier the work on harder surfaces.

    2.

    Note that the Impact Energy is also important for performance, indicating the force of each strike.

  • Volt

    The higher the tool's voltage, the more powerful it becomes and performs tasks more easily, however, higher voltage usually means an increase in weight.

    2. Impact energy is another characteristic that shows the "strength" of the tool.

    18

    Tools that are 18 volts and above are considered high power and their strength is sufficient even for professional work.
