Drill set for all cases

Well what do you expect there are just drill as are all of the same appearance, but here I can tell they are well preserved. I've just drilled with the 8-and 10 and thus drilled about 40 holes in a thick steel beams and they are still going, what the reason was to me at all to buy new OHRER because I all already with 4 cheaper no-name drills had tried on the other hand, while 2 drill had consumed. So there is reason to hope that I still use these drill awhile.
