The screwdriver has reinzuprügeln also the necessary power to really big in Spax wooden beams without pre-drilling in first gear. In second gear, it drills even great and powerful. The one or the other action with a milling drill a hole in a wooden plate widen slightly he puts away easily, although you can hear the needs of the engine properly bring power. The machine is comfortable to hold and is not even under high load hot. The large cooling air grille to the engine ensures the heat produced can possibly equal out. I use the screwdriver Professional partly for hours and so far he has not let me down. To properly power reserves (temporally) to have, I recommend the Lithium Ion 4 Ah battery pack for Ryobi. This keeps the screwdriver at me about 7.30 bis 12 clock permanently by. During this time, approximately 300 holes drilled (aluminum sheet) and 350 screws were processed. Mind you on a single charge! Unless you much with the screwdriver Works recommend the purchase of a second battery to change. Thus the void battery can be charged without time pressure and you can continue working with the reserve battery.
My conclusion: Even for professionals (eg on trade fairs, industry etc) a worthwhile purchase. The screwdriver must not hide from the competition!
