I bought this set because I wanted to drill a (own !!!) cylinder lock. And I had the direct comparison with another HSS Drill Set, which I had taken time as no-name product somewhere. What should I say big, starting with no-name, not yet come far after 5 minutes, then continued with Bosch, another 5 minutes later the lock was broken. And the drill looks as if he would even survive a few more missions. So as so often applies here: Dear times spend a euro more, which may be cheaper in the end. Especially as the set here at a very good price (I paid 10,95) is offered.
