These do it all drill bits are pathetic. The best thing I got in my trade bag which you neglect to say is not for trade use lmfao, is the cases the drill bits came in. They hold cigars really well. Cannot drill 1.2 mm mild steel, bit totally destroyed from one now elongated hole. Cannot penetrate more than 5mm into a house brick, however drilled into the mortar pretty well. You're a fraud and deserve to go broke.
