If we compare this drill with tools of similar power from other manufacturers, then the discrepancy between the weight and power of the tool immediately rushes.
With a large weight of the drill, its power is only 530 watts. Which is quite a bit. We would say that this is very low power for drilling in hard materials such as thick steel or concrete.
At the same time, her engine speed reaches a maximum of about 3000 rpm, but usually hard materials, the same steel, are drilled at low speeds so as not to spoil the drill. Therefore, how much such turnovers are needed is a big question.
The chuck of this model of the BISON electric drill is a standard key chuck for a maximum drill diameter of 13 mm.
If you look at the declared drilling characteristics of various materials by the manufacturer, then there is a clear overstatement. It will take a very long time to drill the same 13 mm thick steel with this drill, so it’s stupid to use this drill for this at all. Here a drilling machine is needed no less.
The drill has a reliable design on bearings, which makes the tool durable enough.
The ZUBR ZDU-530 ERM2 electric drill has a hammer drilling function, but again, due to the low power, it is not worth using drills larger than 6 mm in diameter for these purposes. The tool will heat up very quickly and you will need to make stops to cool the engine, which is very inconvenient.
Even for home use, this tool is not very convenient when working with hard materials and a lot of work.
However, if you need this drill exclusively for working with soft materials such as plastic, wood, thin metal or brick with foam blocks, then perhaps this is a well-reasoned choice. Then this drill may well become a good household helper in the toolbox.
The tool comes with an additional handle and a depth gauge.
They are very useful when drilling blind holes in walls. For convenient long-term work, the tool has a button for fixing the switch, and the start button itself, depending on the pressing force, regulates the engine speed.
Externally, the specified drill has a modern appearance. The case is made of gray plastic without obvious sharp corners. If we consider the popular various manufacturers (meaning the appearance), then this drill is very similar in color to the Interskol electric drill. But Interskol electric drills usually have rubberized grips on the handle, while the described model has a one-piece handle.
The control buttons of the ZUBR ZDU-530 ERM2 drill are made in bright red and are clearly visible on the case.
