In general, a high-quality machine copes with its tasks with batteries, although 1.3 Ah is enough for me; I drilled a safe for them to install an alarm; I drilled metal doors for sensors; a brick for installing devices; I passed them a wall in a log house. With its pros: solidly assembled device good quality plastic well balanced comfortable rubberized handle branded case with practical metal latches metal gearbox . Cons: awkward lighting in the case there are no stampings for drills and bits (although many manufacturers have the same situation)
