And this impression was confirmed when drilling blind rivets (on my motorcycle saddlebags) yesterday. This worked perfectly with the 4-drill! The rotational speed of the battery drill on low speed, the drill planed rivets effortlessly in long chips from the hole, as if they were made of butter. That was fun.
I have no experience of how the drill during drilling of H-beams from behave Krupp Stahl. But this is currently not a typical scenario for me, and therefore for the time being irrelevant to me.
Conclusions in brief:
+ Extremely sharp drills
+ Storage box (aka "Box") from fairly sturdy plastic, with practical closure. If it is closed, it moves nothing.
+ All drill diameter increments that I'll ever need in a small box. Example: 8.5mm to rebuild a bicycle wheel to "Auto Valve" (10mm and to subsequently deburring the hole.)
+ Legible marking of individual drills
- So far, nothing found. Once I find something there to complain to the drills, I will add it here.
For my part, therefore, a clear recommendation.
