For further details:
The Makita 8391 has for the screws 16 steps and in 1st gear (2) 2 torque levels. Generally you should only screw in first gear, because although this is available less line, but a higher torque; the second gear is then intended for Bohreinstellungen; one makes it different and can also Schrauberei in second gear by rattling, it can happen to one that the motor abraucht sometime.
For drilling and screwing anyway the Makita is functioning properly; also the "overspeed" is a wonderful, in order to protect the transmission. The keyless chuck holds likewise, and also a whole makes this cordless drill a well-crafted appearance.
Enclosed include some wood milling, with which one (thus straight and) can mill in spruce timber beams holes example effortlessly. the wood borers are great. Only slightly thicker drill (total in wood / stone / steel) are missing in the enclosed range (there are "only" drill to size 6 available).
The battery was charged by the way in no time; how long it has actually taken place, I have not stopped, but felt it was only a half hour; vll there were also 45 minutes.
The Makita developed an incredible power. I have lashed some screws at a desk with rack structure, which I have built which stood out a bit - mistaken !! Because what is happening !!
The case is very well made; a Systainer but I would have preferred. The essay for German outlets, incidentally, was already attached to the charger. Only the plastic thingy to cover the components and its attachment not particularly like it because it's just a matter of time before there times what breaks and accessories then flies around in suitcases. But so far everything is still OK (is a kind of transparent cover, which is pressed with pressure to the sides in a groove).
All in all a (visually) very nice tool that copes with all the work in the DIY and semi-professinellen field playing. The battery lasts a long time and can be quickly exchanged for the second; until it is empty, the other is charged for a long time again.
My conclusion: just buy it !!
