    This is equipment for amateur use and will not last long with regular use. Better to buy something better right away.
    What will you do? For regular drilling holes for cans, I recommend a more powerful machine, because any other machine will quickly give up the spirit.
    And here is info from another forum:
    "
    1. The diamond bit cuts the concrete - it is designed to work without impact - the diamond wears off when drilling.
    2. Vidia crown knocks a hole like a drill - the rotating movement is used to discharge the spoil.

    Due to the large diameters = large contact area between the drill bit and the wall, a high impact force is required to penetrate the drill bit into the hard material. I would suggest to consider buying a SDS MAX hammer drill with an impact force of 7J, I would like to emphasize not the company's one, for about 400 - 450 PLN. and lace.
    "
    I adhere to the principle that it is better to buy better equipment once, and with proper care and maintenance, you will have peace of mind for years. Some people buy cheap and just exchange.
    However, for such works it is rather SDS MAX and not PLUS ...
