From a technical perspective, the motor power of small water drills is typically between 2-3kW. Taking a 2.9kW model as an example, it can support drilling diameters ranging from 20-150mm, and drilling depths from 0.5-3m depending on the model, meeting the shallow-hole operation needs of scenarios such as building decoration, pipe installation, and electrical wiring. Their weight is mostly controlled between 20-30kg, and with an adjustable auxiliary support, they can be easily operated by a single person, making them particularly suitable for indoor environments with limited space or high-altitude operations.
