  • 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.

    3

    For casual amateur use, 2 to 4 Joules are considered sufficient.

  • Power

    Power indicates the strength of the machine. Usually, the greater the Power of a machine, the easier it can penetrate a surface.

    2. Impact Energy is another characteristic that shows the "power" of the tool.

    900

    Machines ranging from 650 to 1500 watts will handle most household tasks. More watts make it easier to work on harder surfaces.

  • Socket

    SDS - SDS Plus (TE-C)

    SDS sockets have better performance in rotary hammer functions compared to others and are suitable for working on concrete or stone. They are also easy to change drill bits, which can be done with one hand. 2. SDS-Plus (TE-C) sockets have a base diameter of 10 mm and can accept drill bit diameters between 4-30 mm. These sockets are only compatible with corresponding SDS Plus drills.

  • 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.

    We bought it to drill walls. The machine broke immediately. Since then, we take it to the service center every now and then. The handle is not stable, it keeps turning. The cable is too short. Without gloves, it quickly hurts your hand.
    Attention. It doesn't have a safety lock inside. I was trying to make a hole in the corner of the room. The drill got stuck in a concrete beam. The tool turned upside down and injured my hand. Five stitches.
    Better stay away.
