Review on Bit and drill set BOSCH X-Line 33 2.607.019.325, 33 pcs., green by Stanislaw Kosciukiew ᠌

I advise you to buy, it's not expensive, the functionality covers all home needs, I repeat home, if you work and you need a large number of excellent drills, look for another set. For concrete, the maximum diameter is 8mm, for metal 5mm, for wood 8mm, most likely you won’t have enough, but just right for home use ! )
