For a year now I have the Makita BHP 453 Akkubohrschrauber.Ich'm caretaker of several properties. The device is perfectly balanced and is very good thanks to Softgrip inthe hand. It features a 18 volt motor of its power through a 2 speed metal planetary gear to the German Röhm Borfutter (13mm clamping diameter) transfers. With the approximately 40 Nm in first gear you are able to even attract large screws, or to drill large holes with a Dosensenker in wood. The built hammer mill allows holes in a brick wall or calcareous sandstone drilling. Since the Li - ion battery in 20min. is chock-full back can be permanently working with the two supplied batteries in the set. That's good for a lot of screws. He has fallen off the ladder and had times except for a few scratches nichs! Conclusion: You get a sophisticated, suitable for everyday use device with which work very well läßt.Der electric screwdriver may cost a little more at the beginning. But he is also a value and sets out on time paid for - no comparison to the lower priced units from hardware store or online. If it is necessary (nothing lasts forever ..), I will buy it again!
