For "real work" or even renovator / homeowners who sometimes just a few hundred screws in a wooden ceiling
must turn or have to make larger diameter screws in wood or even stone abolut unsuitable.
Once reasonably torque comes into play these soft steel set is simply overwhelmed.
If these things have to "work" properly, a bit for the three- or five times the price is clearly superior.
The holds namely at least 10 times as long (and that's really seeeehr underestimated)
But for all Bastelkeller fine workers, but which do from with little stress and at times just this or that
special bit need for releasing a handful of screws, I can recommend the Set
What I give here? Five stars for price / versatility and zero stars for the quality. The bottom line then makes three ....
