Masonry Drill Bits: Will probably never need a masonry bit 3mm. Depending on the substrate is from 5 mm (for 6 mm dowels) sorting for my purposes sense.
Holzbohrer: rubbish - tips are not centered.
Metal Drill: cutting angle for colored and soft metal bearable unusable for steel.
The box like falling apart and the drill bit is not locked when flipping out him.
Conclusion: If I were BOSCH, I would not let my name from the Far Eastern Billigst_Zulieferer top Print.
