  • Power Supply

    Battery

    Indicates whether the tool operates on battery or directly from the mains. Battery-powered tools offer freedom of movement, while electric ones provide continuous power.
  • Number of Batteries 2

  • Speed Setting

    Ability to adjust the rotation speed according to the task (low speed for screwing, higher speed for drilling into larger walls, maximum speed for drilling into concrete)

  • Voltage

    It corresponds to the power of the tool. Higher voltage means more power and durability for heavy-duty tasks.

  • Battery Capacity

    The battery capacity. The higher the number, the longer the tool's operating time. An average continuous working time is 20-25 minutes per ah, but it always depends on the type of work we are doing.

  • Maximum Motor Speed

    The maximum rotational speed of the engine in revolutions per minute. For drilling tasks, a number of revolutions up to 1500rpm is perfectly satisfactory, as there is a risk of breaking the drill bit due to the increase in temperature above that level, while for screwing tasks higher speeds can be used, especially if the material is soft such as wood or plasterboard.

  • Chuck Diameter

    The maximum size of drill bit or tip you can use. The larger the chuck, the more accessories it fits.

  • Torque Setting

    The ability to adjust the torque of the tool's operation according to the task at hand. (Low torque for easy screwing/unscrewing, high torque for drilling into walls).

  • Impact

    The impact function provides high power to easily and quickly complete even the most demanding tasks.

Brushless
No

Brushless

The advantage that brushless motors have over brushed ones is that they do not have friction since there are no carbon brushes. Without carbon brushes, the motors are more efficient and have a longer lifespan as there is no wear (the carbon brushes in brushed motors wear out with use). They produce less noise, maintain constant torque at all speeds, do not overheat, and require no maintenance.

    Guys, Bosch has gone too far, it's ridiculous, very expensive as a company and with very weak products. Makita is currently by far the best with much better prices. If you want power and something that will last for many, many years, get Makita. DeWalt or Bosch are just a joke and will break down very soon, especially if used professionally!!!!
