Fuel tank capacity
The volume of the fuel tank installed in the drill.
A larger tank allows you to work longer without refueling, but it significantly affects the weight of the tool. Given the peculiarities of the operation of motor drills, in fact it is easier to take breaks for refueling than to keep a large supply of fuel in the unit itself. Therefore, tank volumes are usually small, only in some high-power models this parameter exceeds 2 liters. At the same time, manufacturers take into account fuel consumption and select tanks in such a way that breaks do not have to be taken too often.
Weight
Nominal weight of the drill. Usually, the weight is indicated "dry", without fuel in the tank, and also without taking into account the auger or other working attachment. However, in some models, originally equipped with drills, the weight may be given for the tool with the nozzle installed.
According to this indicator, one can evaluate the general class of the tool: powerful engines inevitably turn out to be heavy, respectively, the heavier the motor drill, the more powerful it is, usually. A massive unit is more difficult to hold (and models weighing from 20 kg are initially made for two operators), but a large weight has its advantages — the tool gets more stable and less prone to vibrations.
