Cheap or expensive, what should be?

What has struck me here ....
... For my home workshop I do not need daily drills. But quite good because I drill not only normal steel but often even hard steels.
For the most important sizes 3mm and 6mm cobalt alloyed drill I have. Now I've been missing from and to other sizes and annoying. But a cassette with Cobalt drill about 40 mhhh ...
I can sharpen drill, I let myself be surprised by this Bosch-set.

Yes I would buy again, has convinced me!
For my applications, such as aluminum common steels and sometimes hardened steel highly recommended.

I am very happy, and it was cheaper than the hardware store. Collective order at Amazon goodness.

To recommend for the longevity of the drill.
Use -Schneidöl
-Without Boring too much pressure
-Speed ​​Adhere (small drill = fast, large = slow)

PS: Of course, the service life will not be as high as cobalt drills or high end drills. Can sharpen itself but you learn very quickly, so it was at least for me.

My Conclusion:
Cheap drills from the hardware store, Tedi, ect. = Scrap
Average mark given drills like this one = Top
Expensive Cobalt drill = better but very expensive
Hardened drill speed steel (M2), temperature treated with nitrite titanium coating = Of course, better drilled and tool steel without problems;)

Whoever complained not run the drill 100% Centric ....
... It is not so important! Many hand drills the drill chuck is worse than so some drills. For bur lengths like this not absolutely tragic. For me, that lays eggs on top to 0.4mm max. 0.7mm and make my drill expensive so it's probably my chuck.
